Offensive Variation and A Short Word about Defense

Posted by nvr1983 on March 19th, 2009

When Ben Allaire isn’t drumming up meaningless college basketball statistics, he’s writing about the Virginia Cavaliers over at Dear Old UVa.  RTC appreciates having Ben stop over this week to make some numerical sense of this year’s NCAA Tournament field.

What the analysis thus far has told you is how consistent a team is, without regard to how good they are.  In theory, a team could be consistently abysmal and do well in its Pythagorean consistency.  Granted, that team would be unlikely to make the big dance, but we wouldn’t have controlled for it.

Take a Pitt as an example.  We’ve seen that Pittsburgh is a maddeningly inconsistent team in terms of offensive efficiency.  As you probably have guessed, it’s a major function of their over-reliance on DeJuan Blair, but it’s a tad bit more subtle than that.  Pitt is first overall in the country at offensive rebounding, again as a function of Blair’s obscene board work.

This reliance on offensive rebounding makes them susceptible to foes; if Blair gets in foul trouble, they have trouble producing points.

Furthermore, they don’t shoot that many free throws relative to their field goal attempt (in an attempt to get more offensive rebounds?).  Free throws can be a consistent and efficient way to get the ball in the hoop.

Back to the main point: perhaps none of these reasons matter for Pitt to succeed.  Maybe Pitt is so outstanding, even their bad times are good times.

That’s why I’ve “devised” a measure of offensive consistency relative to the offensive efficiency.  Basically, I’ve just divided the standard deviation of offensive efficiency by its mean. Statistically, this is known as the coefficient of variation (CV).

The CV often used to assess how wide a distribution of numbers is.  It has an added wrinkle here in that teams are trying to minimize the top (low variation) and maximize the bottom (high offensive efficiency).  Thus, teams want this to be as low as possible.

Think about it like a dart board. The main goal is hit the bull’s-eye. Do you hit it once every ten shots, but otherwise are all over the place or are you consistently off by three inches? Really, you want to hit the bulls-eye often and when you miss, you want to be close to it.

Here are the top/bottom five teams seeded fifth or below in the coefficient of offensive variation:

Rank Top Performers Off CV Bottom Performers Off CV
1 Oklahoma (B12) [2] 0.0954 Illinois (B10) [5] 0.1533
2 North Carolina (ACC) [1] 0.0980 Pittsburgh (BE) [1] 0.1501
3 Duke (ACC) [2] 0.1059 Memphis (CUSA) [2] 0.1438
4 Syracuse (BE) [3] 0.1093 Michigan St. (B10) [2] 0.1418
5 Washington (P10) [4] 0.1119 Louisville (BE) [1] 0.1417

I guess this answers our conjecture about Pitt, but also raised a number of questions about Memphis and Louisville: two teams that many have winning it all.  Will they have enough firepower to last eight games? You have to wonder.

I assume that no one is surprised to see Illinois tops at the bottom considering they’re (1) in the Big 10 and (2) that debacle against Pitt.  Michigan St. has been pretty awful at times as well.

On the left side, we have OU. Jeff Capel has put together a great offensive group in Norman.  Jeff, if you’re reading this, Charlottesville is lovely this time of year.

UNC is no surprise at #2.  The secondary break is king, as is Ty Lawson (when he plays).

Duke is a surprising #3.  I think most people think of Duke as been rather sporadic on offense because they rely on the three so much.  Not so, they can hang with the top teams in the country on offense.

Lastly, I’d like to note that had we not included only the top five seeds, Siena would’ve been tops still.  Fran McCaffery’s crew is really solid on offense. Fran, if you’re reading this, Charlottesville is lovely this time of year.

A final word on filling out your bracket, I’d hoped to do something with defense before today. Alas, it was not to be.  I’ll still probably come up with something about it, but it won’t help you fill in your bracket.  Be cautious with teams that force a lot of turnovers.  From all the analysis that I’ve done, teams that force a lot of turnovers aren’t very efficient on D and are likely to get upset.

Sack Up, President Obama!!

Posted by rtmsf on March 18th, 2009

You probably heard this already, but President Obama released his stimulative bracket today.  What’s notable about this bracket is that he has a serious West Coast bias thing going, and he pretty much goes chalk (choosing four of the top five seeds to advance to the F4).  Here’s the Obama Bracket… surely you can do better than this farcical attempt at knowledgeable basketball (thank you for reading, Mr. FBI Man).

Behind the Lines: NCAA Tournament Day One

Posted by rtmsf on March 18th, 2009

btl-header

This edition of Behind the Lines is emanating from Las Vegas. The Obsessed With Sports crew will be enjoying the first weekend of the tournament from the sports betting capital of the world.

Thursday, March 19th

The 8 versus 9 games are very close, as they should be.

Butler (9) vs Louisiana State (8) -2.5

Behind The Line: Take a look at the over on this one–it’s at about 127. Butler has consistently been going over numbers in this area while LSU scores a lot more than other Horizon League teams.

Texas A&M (9) vs Brigham Young (8) -2

Behind The Line: Both teams have been very good as far as covering as of late. They are a combined 14-6 in their last 20 games. In this case, the spread might play a more minimal role.

Gonzaga is no stranger to being a double digit favorite.

Akron (13) vs Gonzaga (4) -12.5

Behind The Line: Gonzaga is 7-6 this season when they have been favored by double digits.

Connecticut is also familiar with large spreads.

Chattanooga (16) vs Connecticut (1) -20

Behind The Line: UConn is a misleading 3-7 when they are double digit favorites. I say this because a number of their non-conference games didn’t even have lines because they weer favored by so much. Also playing a large role is the competition in the Big East, against whom the Huskies were still favored by more than 10.

According to Bodog the longest shots to win the whole shebang are Binghamton, Morehead State, Morgan State, Radford, Robert Morris and Chattanooga at 1750:1, respectively.

More from Vegas as the week progresses!

East Region Game by Game Previews – 1st Round (pt. 1)

Posted by rtmsf on March 18th, 2009

EAST REGION PREVIEW (By Dave Zeitlin and Steve Moore)

Since there seem to be more than a few obvious picks in the East Region, RTC gives you the bonus coverage you’ve come to expect. Not only do we pick the first-round game – but we also pit a non-basketball alum from each school against each other in a no-holds-barred blog battle. Enjoy.

Thursday Games – Philadelphia, PA

(3) Villanova vs. (14) American (7:20 ET)

SM: Picking a 14 over a 3 is the cool bracket thing to do. Not here. The ‘Nova players could roll out of their dormitory beds, take the train into town and still dismantle the best the Patriot League has to offer. Outside of the 1-16 games, this may be the biggest lock of the first round.

DZ: Yes, an American win would definitely be one of the biggest shockers of the tournament, considering ‘Nova will virtually be playing at home and hasn’t lost to a team with a Pomeroy ranking less than 28 all season. That said, I don’t think the game will be a blowout. Standout Garrison Carr (17.8) leads a senior-laden American team that is on a 13-game winning streak and is returning to the Dance for a second straight year. ‘Nova by 12.

Alumni ThrowdownMaria Bello (Villanova) vs. Goldie Hawn (American): SM: No contest. The Cooler is a highly underrated film. Although, William H. Macy? Really?  DZ: What the hell is a Maria Bello? Maybe I need to see The Cooler. Also, Goldie Hawn scares me here. I think I’ll pass on this one.

(6) UCLA vs. (11) VCU (9:50 ET)

SM: Ever since Seth Davis said he’d “put on a VCU sweatshirt” while falling all over the Rams during Sunday’s selection show, VCU has been a trendy upset pick. Well, count me in. Larry Sanders not only has a great TV show under his belt, but his arms are long enough to give Rick Majerus a real hug. UCLA doesn’t want to be in Philly, and Eric Maynor makes sure the Bruins head home early.

DZ: Maynor might be the most well-known little-known player in this year’s Dance after his shot sent home Duke in ’07, but can we expect him to do it again with a different supporting cast? That’s a lot to ask, especially when the opponent is a UCLA team that will guard his shorts off. Darren Collison and the Bruins may not make their fourth straight trip to the final four, but they won’t be bounced in the first round. UCLA by 7.

Alumni ThrowdownJack Black (UCLA) vs. The Real Patch Adams (VCU): SM: Dr. Adams helps people on a daily basis, while Black is the brains behind one of the finest albums ever, Tenacious D’s self-titled effort. But because Dr. Adams’s story contributed to the downfall of Robin Williams, the nod goes to Mr. Black. DZ: I hope you realize you just picked a comedian who once said “Dude, if you get the nachos stuck together, that’s one nacho” over someone who brings limitless hope and joy to orphans around the world. That pretty much makes you a bad person … but yeah, I agree. The movie Patch Adams did not leave a lasting impression on me, but I consider Saving Silverman one of the most underrated comedies. Sorry, sick children – Black gets the nod.

Thursday Games – Greensboro, N.C

(7) Texas vs. (10) Minnesota (7:10 ET)

SM: I’m already on record as saying that Texas is overrated and overseeded, so I have to go with the Gophers in this battle of two tourney-tested coaches, Tubby Smith and Rick Barnes. Minnesota posted a long-forgotten win over Louisville back in the fall, and has endured plenty of battles in the underrated Big Ten. Plus, I enjoyed two sub-zero days on campus in Minneapolis back in 2004, and could not have met nicer people. The Mall of America was pretty cool, too.

DZ: While it’s hard to pick Barnes over Tubby, I think Texas will avoid the upset here. The Gophers have really cooled off after a great start, winning only four of their last 11 games. And the Longhorns, while also inconsistent, have two go-to players in guard A.J. Abrams (16.3 ppg) and forward Damion James (15.4 ppg). Eleven straight tourney appearances won’t hurt either. Texas by a bucket.

Alumni ThrowdownMatthew McConaughey (Texas) vs. Tony Dungy (Minnesota): SM: Both have stood on the sidelines at big football games, but only Dungy really belonged there. The all-around good guy Dungy wins this in a landslide. DZ: What a weird matchup. You can’t say anything bad about Dungy, but I don’t dislike McConaughey nearly as much as Stewie from Family Guy. And I respect the fact that he’s essentially played himself in all of his movies, even if it did seem a little odd in We Are Marshall. Either way, I’m going with McConaughey in a major upset.

(2) Duke vs. (15) Binghamton (9:40 ET)

SM: As much as I would like to pick my America East brethren here, I have to believe that Jon Scheyer will get away with enough traveling violations to help his Blue Devils edge the Bearcats. Seriously though, D.J. Rivera is a great player (even if not a great student), but he can’t beat the McDonald’s All-Americans Coach K brings deep off the bench. Blue Devils run away late for a 15-point win.

DZ: I would love, love, love to see Binghamton keep it close – if only for my oldest friend who’s making the trip to Greensboro to see his alma mater. But I don’t see it happening. Duke is bound for a deep run after a couple of early exits, and Coach K will pick apart an athletic but undisciplined Binghamton team making its first trip to the Dance. This one could get ugly … Duke by a bunch.

Alumni ThrowdownRichard Nixon (Duke) vs. Billy Baldwin (Binghamton): SM: Be honest, you expected BU’s most famous alum, Tony Kornheiser. But we throw curveballs here at RTC. Baldwin has had a less-than stellar film career, but I mean, even a Baldwin can beat Richard Nixon in this bracket. DZ: What is this? Neither of us were alive for the Nixon presidency and I can’t remember ever thinking about Billy Baldwin once. Umm … I’ll shake things up and go with Nixon, only because I liked Frank Langella in Frost/Nixon and because Baldwin is a Yankees fan. Wait, weren’t we supposed to be talking about basketball?

South Region Game by Game Previews – 1st Round

Posted by rtmsf on March 18th, 2009

North Carolina v. Radford (#1 v. #16)

This is probably the most interesting 1 v. 16 in the tournament. North Carolina will be heavily favored, and will probably win the game, but the Radford Highlanders are no slouch. They have four players that score in double digits, led by 7-foot-0 Artsiom Parakhouski, who is leading the team in scoring (16.3), rebounding (11.2). Matching Parakhouski with Tyler Hansbrough will be fun to watch. One analyst said the Tar Heels don’t even need to start Ty Lawson, but this is the NCAA Tournament, if he is ready to go, he will play.

The Tar Heels are more talented and deeper than Radford, so this wouldn’t be the game to hope for a monumental upset. Radford’s best win is against VMI in the Big South Conference Final, and they have been blown out by every team they have played in a major conference. I will still tune in, just to see Hansborough post up Parakhouski.

LSU v. Butler (#8 v. #9)

This game pits two teams that were under-seeded by the NCAA and as a result, will give the viewers a competitive, fast-paced game to watch. Both teams are in the middle of the tournament pack in terms of offensive and defensive efficiency but they both have great athletes and fun players to watch.

The key match-up will be on the wing where Butler’s Gordon Hayward and LSU’s Marcus Thornton will see a lot of each other. Both players can light it up offensively in a number of ways. Matt Howard and Chris Johnson should be a good one down low. Johnson has a significant height advantage, but Howard scores  a lot of points of hustle, and can be a crafty scorer in the post.

Illinois v. Western Kentucky (#5 v. #12)

Everyone’s trendy upset pick is looking even better with the news that the Illini senior point guard, and best defender, Chester Frazier, is a “long shot” to play according to coach Bruce Weber. But, the Hilltoppers are not the same team they were last year when they made it to the Sweet 16 before losing to UCLA; however, they are good.

Illinois has not played well away from home (4-6), and Portland is quite a trip from Champaign. The Illini have not shot well from the field, and they will need to get Mike Davis (11.6 pts/game, 53.2 FG%) involved early if they want to keep up. The Hilltoppers have four players between 6-foot-1 and 6-foot-5 who average double digits and they will run away with this one if the Illini aren’t careful.

Gonzaga v. Akron (#4 v. #13)

I don’t think this game will be as close as many people think. The ‘Zags are one of the hottest teams in the country having won 18 out of their last 20 games, and dismantled Saint Mary’s 83-58 in the WCC Final.

The ‘Zags are in the top 10 in both offensive and defensive efficiency, and Akron just does not have the firepower or the athleticism to keep up with Gonzaga for 40 minutes. Akron has the advantage in depth though. The Zips can go ten deep, and defend well. If they can wear down Jeremy Pargo, they have a chance.

Arizona State v. Temple (#6 v. #11)

Anyone who thinks these teams are both one-man shows is sadly mistaken. There is absolutely no doubt the Sun Devils’ James Harden and the Owls’ Dionte Christmas can take over a game offensively, the there will be another battle to keep an eye on down low.

ASU’s Jeff Pendergraph (14.5/8.4/66.5%) and Temple’s Lavoy Allen (10.9/8.9/57.9%) will be banging on the low blocks, and crashing the glass will be extremely important for both teams. The role players will be the deciding factor in this game, and if ASU point guard Derek Glasser minimizes mistakes, and finds Harden often, ASU has the advantage over the surprising Owls.

Syracuse v. Stephen F. Austin (#3 v. #14)

The Orange enter the tournament playing some of their best basketball of the season, and despite their fatiguing run through the Big East Tournament are a heavy favorite over the Lumberjacks. Jonny Flynn and Andy Rautins have been absolutely on fire, and there is no one on the Lumberjacks roster to match up with them.

The Lumberjacks are an interesting case. They are in the top 20 in defensive efficiency, but are 242nd in offensive efficiency. They beat Drake in December, but they also lost by 16 to Arkansas and 14 to Texas Tech, and neither one of those teams are as good as the ‘Cuse. The Lumberjacks will rotate in a lot of guys, and they only stand a chance if Syracuse isn’t fresh and comes out slow.

Clemson v. Michigan (#7 v. #10)

Both teams and their coaches come into the game with something to prove. The Tigers have to prove they are for real this year, and that they can make noise in the tournament, and the Wolverines need to prove their system works outside of the plodding Big Ten.

The game will feature two of the more athletic combo forwards in Clemson’s Trevor Booker and Michigan’s DeShawn Sims. It will be interesting to see if the two guard one another. But, the Wolverine offense goes as Manny Harris goes, but he is inconsistent as he has nine games with single-digit point totals. If Clemson’s KC Rivers can frustrate Harris, the Wolverines will have a tough time offensively.

Oklahoma v. Morgan State (#2 v. #15)

On paper, the Sooners have a clear advantage in every facet of the game, but the Bears have beaten both DePaul and Maryland, and played close games with Mississippi and St. Mary’s. The problem is, they don’t have anyone who can guard Blake Griffin, or Willie Warren.

Oklahoma has been struggling late and if ever there was a time to strike for Todd Bozeman’s club, now is the time. But they might not have enough weapons to keep up with the Sooners, and Griffin will get to have his way on the low blocks.

Pythagorean Consistency

Posted by rtmsf on March 17th, 2009

When Ben Allaire isn’t drumming up meaningless college basketball statistics, he’s writing about the Virginia Cavaliers over at Dear Old UVa.  RTC appreciates having Ben stop over this week to make some numerical sense of this year’s NCAA Tournament field.   

pythag-cartoon

A great man once said, “Our offense is like the Pythagorean theorem: There is no answer.”

Unfortunately, that man was Shaquille O’Neil and it’s funny because he couldn’t be wronger… er, more wrong

The Pythagorean theorem does have an answer and it’s going to help us examine which teams are most consistent on offense and defense together.  Last time, I gave you a scatterplot of all 65 teams’ consistency on offense and defense.  Using the Pythagorean theorem (or you might say Euclid distance), I’m calculating the distance between each point on the plot and the origin (0,0).  We’ll call this distance: Pythagorean Consistency (PC for short).

This will combine the two measures into one and tell us exactly how consistent a team is.  Now, remember as I said last time, this isn’t necessarily a measure of who’s best.  If you want that, kenpom.com has a myriad of ways of determining it.  It’s a measure of who performs according to expectation.

Let’s glance at the top and bottom ten list:

Note: Conference in parentheses; seed in brackets.  Data source: kenpom.com

I find this to be a fascinating list.

It’s Christmas in March

Posted by rtmsf on March 17th, 2009

Dave Zeitlin is an RTC contributor.

I’ve often said that the first Thursday of the NCAA tournament is like Christmas for me. So what better time to make a Christmas, err, a March Madness wish list? Here, in no particular order, is what I want as the best three weeks in sports begin:

xmas-tree-ornament-bball

  • To hug a stranger at a bar while cheering for a player I’ve never heard of at a school I don’t know anything about.
  • Anyone who roots against a big underdog for the sake of his bracket to be forced to watch exclusively LPGA tournaments through the rest of March.
  • Another George Mason to make the Final Four. I’m looking at you, Siena.
  • A 16 seed to finally win a game, and not just for the free Arby’s burger. (This promotion, though, is sort of funny, especially this quote: “Each year at this time, people crave that Cinderella story – the team that takes everyone by surprise. Our new Roastburgers offer an unexpected change from standard greasy burgers.”)
  • A brawl between Gary Williams’ sweat and John Calipari’s gel in Round 2 (speaking of greasy things)
  • A cat-fight between Fran McCaffery’s wife and Rick Pitino in Round 2 (sorry, I must have that mascot brawl on my mind).
  • A game that goes seven overtimes. Six is nothing.
  • A buzzer-beater that will make Bryce Drew say, “Now that was impressive.”
  • A moment so memorable, I’ll always remember where I was when I saw it. (Unless I’m with Jim Calhoun. Wait, why would that happen?)
  • Someone just as fun as Stephen Curry to become the new Mr. March.
  • Greg Paulus to become the new Miss March.
  • Fran Dunphy to win a game. He deserves it.
  • Bob Huggins to lose a game. He deserves it.
  • Jonny Flynn to keep doing his Energizer impression
  • To win my pool, though I’ll settle for keeping my bracket alive past the first day.
  • To watch my alma mater, Penn, try to win a game. What’s that? The Quakers aren’t in the tournament for the second straight year? And they had one of the worst seasons in recent history? Excuse me while I jump from the Palestra rafters.
  • Jay Bilas to stop hating on the little guy. How many mediocre schools from BCS conferences to do we need to see before we realize it’s the upsets that make this tourney tick?
  • Binghamton’s D.J. Rivera to get his revenge for the ultimate snub by torching the team everyone loves to hate. Speaking of which …
  • To find a new villain other than Duke. How about … let’s see … um …. Oh, hell, I’m sticking with Duke.
  • The announcers doing the Cornell game to abstain from saying things like “I thought Ivy League kids were smart” after a bad turnover. SAT jokes are a no-no, too.
  • Players to stop thanking God after wins. I’m OK if Mississippi State’s Jarvis Varnado repeats this gem though: “I’ve got to use my quickness to outquick the opposing opponent.”
  • Bob Knight to offer a formal apology for once saying, “All of us learn how to write in the second grade. Most of us go on to greater things.” Hey Coach, those words you’re stringing together for your new website with fellow jerk knowledgeable hoops personality Billy Packer. I’m not entirely sure but I think it’s called writing.
  • Gus Johnson to yell even louder.
  • Any commentator who says the expression “body of work” more than twice in one sentence to stop getting lessons in awful announcing from Suzyn Waldman.
  • Gonzaga not to ruin my bracket for the millionth straight year. Please? If I win my pool, I’ll split the money with you, Heytvelt. You can use that cash for your supply of – and moving on!
  • The dude who said, “I’m the weather man” to come back into my life.
  • To hear my stepdad explain the same last-second play he created years ago while lamenting, “No one ever does this.” (It’s March. Everyone’s a coach.)
  • A team with a great story to rally behind. Cleveland State and North Dakota State seem like good choices, but I’m open to suggestions.
  • To tune out anything that has to do with the economy, the wars, the demise of newspapers, octomoms and Dane Cook … and get sucked into a world of college hoops for three straight weeks, remembering so many great shots, players and moments that I have enough material to write another column gushing about March Madness 20 years from now.
  • And, of course, to cry during One Shining Moment. I mean, what?

So that’s my wish list. May Santa, I mean Greg Gumbel, come down the chimney and bring it to me.

Brackets, Parentheses, Braces: Why You Should Be Wary of Pitt

Posted by rtmsf on March 16th, 2009

When Ben Allaire isn’t drumming up meaningless college basketball statistics, he’s writing about the Virginia Cavaliers over at Dear Old UVa.  RTC appreciates having Ben stop over this week to make some numerical sense of this year’s NCAA Tournament field. 

At its heart, the NCAA Tournament is about consistency.  Just about all the teams (OK – maybe not Chattanooga) are qualified to make some sort of a deep run.  The key is avoiding that one downer of a game that knocks a team out.

So, how should we look at consistency?

Well, it turns out there’s numerous ways to define consistency. Ken Pomeroy takes it to mean how volatile a team’s winning margin is.  John Gasaway has dubbed it “The Winehouse Factor” after the roller-coaster-like life of Amy Winehouse. Joe Morgan uses it as an adjective to describe a baseball player’s fielding abilities, a team’s starting pitching, a hitter’s swing, the running the base paths, Jon Miller’s voice when dressed in drag, and the way his wife makes mashed potatoes.

Here’s the definition I’m proposing: when team X steps onto the court, can we expect what we’ve seen previously from team X, on average?  Is team X’s offense white hot one night then colder than Jell-o pudding pops on another?  Does the defense go through stretches where they stink, then miraculously are dominant?

I’ve taken all 2,126 performances from the 65 teams that have made the NCAA tournament from kenpom.com and plotted the standard deviation of the offensive efficiency versus the standard deviation of the defensive efficiency.
