Beware the Polls: Overperforming Teams Regress in NCAA Tournament

Posted by Will Ezekowitz on March 14th, 2017

Preseason rankings may seem irrelevant when it comes to college basketball, but history has shown that their predictive value are surprisingly important. For example, as we have shown in this space before, the preseason poll is in fact just as predictive of a run to the Final Four as the current AP Poll. The reasoning behind this phenomenon is that the preseason polls take into account all of the changes that the mathematical models have more difficulty accounting for (i.e. coaching changes, big recruiting classes, injuries, etc.). The conventional wisdom entering the season is actually fairly sophisticated and smart.

Given this intuition, let’s examine the teams that defied that wisdom throughout the season and went from unranked in the preseason to ranked in the final AP poll before the NCAA Tournament. Had the preseason polls gotten something wrong? Or did these over-performing teams regress back to their expectations in the postseason? Using the last 10 years of data that includes seed win expectation data from fivethirtyeight.com, I investigated. Of the 97 teams who qualified for analysis, 32 (33%) of those teams outperformed their win expectations in the NCAA Tournament while 65 (67%) underperformed. As a whole, a group that was expected to win 138.8 games over the 10-year sample won just 107. A statistical T-test found this difference statistically significant. In fact, only one team — Kemba Walker’s 2011 National Championship team, Connecticut — even made the Final Four.

Previewing the 2017 Big East Tournament

Posted by Justin Kundrat on March 8th, 2017

Here we are again: four straight days of Big East basketball in the world’s most famous arena, Madison Square Garden. The conference is likely to follow up last season’s five-bid NCAA Tournament mark with seven teams this year, all of which will be vying for better seeding this week in New York. The other three teams are looking at a frenzied series of as many as four straight games, their only avenue to the Dance in what would be a surprising run to the Big East Championship.

Here’s a printable version of the bracket: 2017 Big East Tournament Bracket

And the Winner is: Villanova

The obvious but boring pick. Even amid a slew of injuries and an undersized but shockingly effective lineup, the Wildcats have again found their way to the top of the Big East totem pole. Few teams have been able to slow down an offense churning out 1.23 points per possession — as a matter of fact, games at Butler (0.99) and at St. John’s (0.99) were Villanova’s only two instances under 1.0 PPP. Sophomore star Jalen Brunson is arguably the most underrated point guard in the country, embracing an old-school style of play that lulls defenders to sleep before blowing by them. Every rotation player with the exception of one is a capable three-point shooter, and the incessant ball screen switching on the defensive end has remained effective because entry passes are such a persistent headache. There are some chinks in the armor, however, as Butler has demonstrated. Crowding the paint on drives and staying down on ball fakes can slow the offense, occasionally causing this team to lose its mojo.

Big East Bubble Watch: Volume II

Posted by Justin Kundrat on March 2nd, 2017

A positive resulting from the recent struggles of Creighton and Xavier is the opportunity it has afforded the conference’s bubble teams. At the beginning of the season, five was a fair benchmark for possible NCAA Tournament bids coming out of the Big East this season. Now, with just one regular season game remaining for each team, as many as seven teams could hear their names called on Selection Sunday. At the expense of quality seeding has come quantity, which might prove to be a boon given the unpredictable nature of March Madness. Here is where those seven teams stand as we head into of the final weekend of the regular season. RPI and strength of schedule (SOS) figures are from RPIForecast.com.

Locks

  • Villanova: 27-3 (14-3); RPI: 1; SOS: 24
  • Butler: 23-6 (12-5); RPI: 10; SOS: 11
  • Creighton: 23-7 (10-7); RPI: 24; SOS: 44

Analysis: These three teams have made things pretty easy for themselves — even losing out would not be enough to destroy their NCAA Tournament hopes. Villanova is a virtual lock for a #1 seed, probably in the East Region; Butler has climbed its way up to the #3 seed line; and Creighton should find itself in the #5 to #6 range. With the right match-ups, all three are Sweet Sixteen contenders.

Should Be In

Xavier Has Lost Six Games in a Row and is Reeling as March Arrives (USA Today Images)

  • Xavier: 18-12 (8-9); RPI: 35; SOS: 7

Analysis: The Musketeers’ awful slide has continued with the once 18-6 team having now lost six games in a row. A home loss to Marquette does not help matters but it alone is not yet enough to knock the Musketeers to the fringe. Xavier has gone 0-6 vs. the RPI top 25 this season, but it has avoided any bad losses and still boasts a total of eight top 100 wins. The concern for Chris Mack‘s team at this point isn’t so much its seeding but just how poorly it might perform in the NCAA Tournament. The Musketeers’ last six games have been a disaster on the defensive end.

2016-17 RTC Top 25: Week 15

Posted by Walker Carey on February 27th, 2017

The penultimate week of the college basketball regular season is in the books, and it was a week marked by a few top teams suffering surprising defeats. First, #2 Villanova saw its seven-game win streak end Wednesday when #12 Butler went into Philadelphia and used an 18-0 second half run to catapult itself to a 74-66 victory. An even more stunning upset took place Saturday when previously undefeated #3 Gonzaga saw an early 16-point home lead disappear in being vanquished by a plucky BYU squad, 79-71. Not only did this loss end Gonzaga’s bid at a perfect regular season, but it also began conversations regarding if the Bulldogs are actually worthy of a number one seed in the upcoming NCAA Tournament. This season has been defined by the unexpected, so it is only reasonable to assume that more craziness will occur during the final week. Hopefully we will also see some of it carry over into the postseason. This week’s Quick N’ Dirty after the jump.

Big East Bubble Watch: Volume I

Posted by Justin Kundrat on February 23rd, 2017

Selection Sunday is fast approaching and remaining schedules provide dwindling opportunities to make the cut line for the NCAA Tournament. Given how wide open the Big East has been this season (thanks in large part to a number of injuries affecting Xavier and Creighton), there is an unusually large number of conference teams still with a fighting chance. Here is where those teams stand as we head into one of the final weekends of the regular season. RPI and strength of schedule (SOS) figures are from RPIForecast.com.

Locks

Villanova and Butler are Two of the Big East’s Mortal Locks (USA Today Images)

  • Villanova: 26-3 (13-3); RPI: 2; SOS: 29
  • Butler: 22-6 (11-5); RPI: 11; SOS: 12
  • Creighton: 22-6 (11-7); RPI: 26; SOS: 48

Analysis: These three teams have made things pretty easy for themselves — even losing out would not be enough to diminish their NCAA Tournament hopes. Villanova is a near-lock for a #1 seed even after last night’s home loss to Butler, while the Bulldogs and Bluejays should find themselves on the #4 or #5 seed lines.

Should Be In

  • Xavier: 18-10 (8-7); RPI: 22; SOS: 8

Analysis: Even accounting for the season-ending injury to Edmond Sumner, Xavier shouldn’t have needed to worry about which tournament it would take part in at the end of the regular season. But an ankle injury to leading scorer Trevon Bluiett has changed that perspective. Bluiett was back in action on Wednesday night, but the Musketeers regardless dropped their fourth consecutive game in ugly fashion at Seton Hall, and their upcoming schedule isn’t favorable. Still, three more losses would put Chris Mack‘s team at 18-13 with an RPI of ~38, which likely means squarely in the field. On the plus side, Xavier has been getting much better contributions from its post players, especially RaShid Gaston, which was a major concern earlier this season.

2016-17 RTC Top 25: Week Eight

Posted by Walker Carey on January 9th, 2017

The second week of conference play has wrapped up and with it has come a new team in the #1 spot. Baylor has taken the reins as the top team in the RTC25 after wins over Iowa State and Oklahoma State moved the Bears to an unblemished 15-0 on the season. Scott Drew’s squad moved up with some help from #15 Butler, which ended #2 Villanova‘s reign with a 66-58 upset victory over the Wildcats on Wednesday night. Things will not get any easier for Baylor this week, however, as the Bears will arguably face their toughest test of the season in traveling to Morgantown to take on #8 West Virginia. There is consistently quite a bit of turnover in the RTC25 during conference play, so be sure to keep an eye on the poll each week as the college basketball season remains fluid. This week’s Quick N’ Dirty Analysis of the RTC25 is after the jump.

Big East Power Rankings: New Year’s Edition

Posted by Justin Kundrat on January 4th, 2017

With conference play just getting under way, it feels like an appropriate time to re-establish a hierarchy within the Big East. Let’s take a look at the first Big East Power Rankings of 2017.

#1 Villanova. Forget all the Josh Hart talk for a minute — let’s instead pay tribute to Jalen Brunson, who tallied a career-high 27 points last weekend in Villanova’s biggest test to date at Creighton. With a short seven-man rotation and spotty scoring contributions from a number of those players, the Wildcats had seemed to be over-relying on Hart for their production. But Brunson’s tremendous feel for tempo and timing might be the most under-appreciated facet of the team’s elite offense. A major reason why Villanova won the game was because it successfully slowed the pace down the stretch and reduced the quick outlet passes that Creighton uses to generate high percentage shots.

#2 Creighton. It was terrible timing for the Bluejays to log their worst three-point shooting performance of the season against Villanova. Creighton came into the game connecting on a blistering 45 percent of its perimeter shots on the year, but only managed a paltry 6-of-24 outing on Saturday. Off night aside, freshman center Justin Patton continues to build on his stellar play in the non-conference season. The seven-footer notched 18 points on 9-of-12 shooting and gives the Bluejays a consistent scoring threat in the post to complement their numerous outside shooters.

#3 Xavier. Without the steadying hands of point guard Myles Davis, the Musketeers have experienced a roller coaster of a season. Evaluating Xavier without his presence in the lineup doesn’t do Chris Mack’s team justice. Trevon Bluiett and JP Macura can score in bunches and Edmond Sumner has steadily grown into a sure-handed ball-handler, but the Musketeers need Davis. Per HoopLens, no player on Xavier’s roster last year had a bigger offensive impact.

His 38 percent shooting from deep undoubtedly spaced the floor, but his more important contributions were in ball movement and facilitation — Xavier’s assist rate is currently the lowest it has been in four seasons.

2016-17 RTC Top 25: Week Five

Posted by Walker Carey on December 19th, 2016

As we approach the end of the non-conference portion of the regular season, three RTC25 teams over the weekend earned noteworthy resume-enhancing wins over three other RTC25 teams. First, #14 Purdue used great interior play from sophomore forward Caleb Swanigan to overcome a 14-point halftime deficit in an 86-81 victory over #22 Notre Dame. In the follow-up game at the Crossroads Classic, #13 Butler used a dynamic performance from junior Kelan Martin to beat #14 Indiana by five points. In Saturday’s – and likely the season’s – best game, #6 Kentucky rode freshman guard Malik Monk’s insane 47-point game to a hard fought 103-100 triumph over #8 North Carolina. Conference play is just around the corner, but there is still a little time for some teams to notch a few more non-conference wins that will matter on Selection Sunday. This week’s Quick N’ Dirty Analysis of the RTC25 is after the jump.

2016-17 RTC Top 25: Week Four

Posted by Walker Carey on December 12th, 2016

Another week of college basketball is in the books, and with it came three previously-unbeaten squads suffering their first setbacks of the season. First, #16 Butler experienced its first loss last Wednesday when it traveled to Terre Haute to take on a feisty Indiana State squad that emerged victorious with an impressive one-point win. The Bulldogs, however, bounced back on Saturday with a nice home victory over a solid Cincinnati team. #20 Saint Mary’s was the next unbeaten to fall, as the Gaels were thoroughly outplayed in Thursday’s home loss to a pesky UT-Arlington team that already has a win over Texas. Much like Butler, the Gaels bounced back with a home victory over UC Irvine on Sunday. #22 Notre Dame was the final unbeaten of the week to fall, as Mike Brey’s squad gave #1 Villanova all it could handle before bowing out with a 74-66 defeat. There are now only seven unbeatens (#1 Villanova, #4 UCLA, #5 Baylor, #7 Gonzaga, #11 Creighton, #18 South Carolina, and #24 USC) remaining one month into the season, so keep an eye on each of these squads as we move into the holiday season and approach conference play. This week’s Quick N’ Dirty Analysis of the RTC25 is after the jump.

Tyler Lewis is Hitting His Stride in Running Butler’s Offense

Posted by Mike Knapp on December 1st, 2016

It is hard to tell from just looking at the 5’11”, 157-pound senior, but once upon a time Butler point guard Tyler Lewis was a McDonald’s All-American. Despite limited size, his creativity as a passer and fearlessness in attacking the basket caught the attention of multiple high-major schools, including his ultimate destination, North Carolina State. With playing time fluctuating over two seasons in Raleigh, Lewis decided to transfer to Butler, where a promising start to his junior season gave way to decreased importance after the new year. Lewis entered his final season in college basketball as the only significant holdover in Butler’s backcourt. He has not disappointed.

The Bulldogs are off to an impressive 7-0 start this season and their senior facilitator is a major reason why. The veteran floor general is only averaging a pedestrian eight points per game, but he has been one of the more efficient guards in college basketball through the first couple weeks of the season. Lewis’ offensive rating of 133.3 is the second highest on the Butler roster and is good enough for 83rd nationally. He is also shooting a blistering 77.3 percent from two-point range (24th), and is 5-of-11 on three-point attempts so far this season. Furthermore, his effective field goal percentage of 74.2 percent ranks among the top 20 in the sport.
