Forecasting Washington’s Zone Defense

Posted by Adam Butler on January 18th, 2018

No team in college basketball has played more zone defense this season than Mike HopkinsWashington club. As a Pac-12 aficionado, you know that the Huskies’ new head coach was a long-time assistant (21 years) of Jim Boeheim at Syracuse. As a college basketball aficionado, you know all about Boeheim’s famous zone defense. Hopkins has brought the defensive scheme across the country, and as a result, the Huskies have been a pleasant surprise through the first half of the season. Considering its uniqueness and Washington’s early success in employing it, a forecasting evaluation of the zone for the rest of this season is worthwhile. Its basic tenet is engineered to dare opponents to shoot from long distance. At Syracuse, 44.8 percent of shot attempts against its zone come from beyond the arc, which is very high (11th nationally). Washington’s opponents, by way of comparison, are allowing 36.7 percent of the shots against them from distance, roughly equal to the national average. This gap is in part related to the Huskies’ faster offense, clocking in with the 71st-swiftest offensive possession average in the game (compared with Syracuse’s 325th-slowest). This increase in allowing long-range shooting comes as a big change from the former regime in Washington. Lorenzo Romar’s Huskies never allowed more than 30 percent of opponents’ shots to come from beyond the arc.

Since Washington has seemingly announced its defensive strategy for the foreseeable future, how might the zone project on its new coast? To date, the gamble has paid off, as the Huskies through five conference games have “held” Pac-12 opponents to a league-best 27.9 percent from three-point range. Pac-12 teams are making 35.8 percent of their three pointers this year, 12th-best nationally as a conference. To try to understand what this might mean for Hopkins’ team, assuming he plans to continue to dare teams to shoot threes, the league has historically been average from distance. A peek:

Peaking at the Margins: Washington’s Luck and Other Pac-12 Points

Posted by Adam Butler on January 10th, 2018

According to KenPom’s luck rating, Washington is the most Irish team in the country. Let’s now dissociate ourselves from preconceived notions of luck and consider both what the rating means (you can read about it here) and more relatable measures of success and expectations. To synopsize the luck statistic, this is a measure of a team’s success relative to expectations (as established by their efficiency ratings). At 12-4 overall, with an adjusted efficiency differential of just +5.44, the Huskies sit ahead of similarly efficient teams in terms of wins and losses (although most have between one to three more losses). Consequently, they rate 108th by KenPom, or slightly above average. What do other margins say about the rest of the Pac-12? As we’ve established, the Huskies are the luckiest team, but what else can 17 or so games tell us about the remaining and critical two-and-a-half months of Pac-12 Hoop?

To start the conversation, I examined scoring differential (total points for minus points against), the Synergy Sports points per possession margins and the aforementioned KenPom adjusted efficiency margins. The Pac-12 results:

Team W L Scoring difference PPP difference KP difference
Arizona 12 4 171 0.127 20.17
Arizona State 13 2 252 0.185 20.08
UCLA 12 4 130 0.100 13.91
USC 11 6 142 0.078 13.87
Utah 10 5 121 0.122 11.88
Oregon 11 5 179 0.125 10.66
Washington 12 4 55 0.050 5.34
Colorado 10 6 28 0.016 4.89
Oregon State 10 5 95 0.077 4.6
Stanford 8 8 -6 0.002 4.34
Washington State 8 7 1 0.043 0.51
California 7 9 -84 -0.088 -2.59

 

Some quick notes followed by a few takeaways: 1) scoring differential is a predictor of success and usually an indicator that you’re a really good team regardless of record, 2) The PPP difference column is based on Synergy data, which accounts raw points per possession information into its metric (i.e., it’s neither a prediction of possessions nor adjusted for strength of schedule, home/away or otherwise), 3) a reminder that the KenPom difference includes the aforementioned adjustments.

Washington on the Come Up?

Posted by RJ Abeytia on December 8th, 2017

Washington, a team left for dead by the pundit class before the season even started, showed plenty of bark and bite earlier this week in snagging the Pac-12’s best non-conference win of the season versus #2 Kansas in Kansas City — functionally speaking, the Jayhawks’ alternate home court. The question now becomes whether such a monumental win gives any indication that the Huskies’ level of play is sustainable? Three things stand out about Washington’s win: First, Mike Hopkins‘ club won the three-point battle. Second, the Huskies kept Kansas off the free throw line by defending cleanly and effectively. Finally, they got a 19-point, five three-pointer masterpiece of an offensive performance from Matisse Thybulle. So to what extent were these three pillars of victory outliers?

Per KenPom, Washington on the year is shooting 33.5 percent from behind the arc and its opponents are shooting 37.1 percent. The Huskies get 25.2 percent of their points from the three-point line, which rates 294th in the country, but logged 36.4 percent (27) of their points from distance on Wednesday night while holding Kansas to only 25 percent shooting beyond the arc. On the year, the Huskies send opponents to the line at a 34.2 percent FTA/FGA rate, but they allowed the Jayhawks just eight free throws against 62 field goal attempts in Kansas City. That’s converts to a stellar 13 percent FTA rate that would make Washington one of the cleanest defending teams in the country if they were to maintain that identity on a nightly basis. Thybulle’s 19 points were built on a great shooting night resulting in a 177.0 Offensive Rating for the game. Last year Thybulle carried a respectable 106.7 ORtg and is currently at 104.5 this season. Was his sharpshooting (five threes) against the Jayhawks an ascent back to his normal mean? Washington should probably hope so, as his body of work last year (41 percent on 131 attempts) suggests that’s the case.

Ten Questions to Consider: Hall of Fame Classic Tips Off Weekend Action

Posted by Matt Eisenberg on December 8th, 2017

The best way to start a weekend of college basketball is by having a quality triple-header on Friday night, and the Hall of Fame Classic in Los Angeles will deliver that to us.

Trae Young Headlines a Strong Group of Teams in Los Angeles Tonight

  1. Which will prevail — good offense or good defense? The Hall of Fame Classic begins this evening with a match-up between St. John’s and Arizona State. Arizona State is ranked among the top 20 nationally in offensive efficiency, three-point percentage, and two-point percentage, while St. John’s ranks among the top 20 in effective field-goal defense, turnover, block and steal rates. In their one loss, the Red Storm allowed Missouri to shoot 51 percent from distance and gave up 26 free throws.
  2. Can USC end its losing streak? The second game from the Staples Center tonight features a pair of interesting teams in Oklahoma and USC. After starting the season 4-0, USC has dropped its last two games. One area that has let the Trojans down is fairly simple — shooting the ball. In its first four games, USC shot 41 percent from beyond the arc; in losses to Texas A&M and SMU, USC shot just 27 percent from distance. If the Trojans fail to get a win tonight against Oklahoma, USC’s resume will be devoid of a quality non-conference win.
  3. How will TCU fare with the late tip-off time? Not only does TCU have to prepare for a talented and undefeated Nevada squad, but the tip-off time back home in Fort Worth will be midnight. While TCU has held three opponents to under 30 percent three-point shooting this season, the Horned Frogs tonight face Nevada’s Caleb Martin and Kendall Stephens, a pair of 6’7″ forwards who are each shooting better than 44 percent in high-volume three-point attempts.

ACC Weekend Preview: November 17-19

Posted by Mick McDonald on November 17th, 2017

While most of the big tests for ACC teams begin next week, there are still some intriguing match-ups on the schedule this weekend. Here are the key games that will act as your appetizers before the main course of Feast Week starting in earnest on Monday. (all ratings are via KenPom as of Thursday night):

Virginia Travels to Richmond for a Tough Intrastate Battle Today (USA Today Images)

  • Virginia at VCU (#89): Don’t forget about this Friday afternoon tip-off in Richmond. Expect the Siegel Center to be rocking. The raucous atmosphere mixed with VCU’s signature defense will be a nice test for a young Virginia team, especially point guard Ty Jerome. He holds a 23.5 percent turnover rate through two games and will need to be extra careful handling the ball against pressure. Isaiah Wilkins is one of the top defenders in the country, but he’ll need to be at his best to slow down VCU’s Justin Tillman. The 6’7” Tillman (20.5 PPG, 78.3% eFG) has been dominant in the Rams’ first two games of the season.

Deep Diving into the Pac-12 All-Freshmen Team

Posted by RJ Abeytia on March 7th, 2017

Earlier this season we arrived at a formula for evaluating the most efficient freshmen in the Pac-12. Essentially, we took net efficiency differential and factored in a player’s individual defense relative to his team. As of January 9 — the rough midpoint of the regular season — these were the five most efficient conference freshmen.

  1. T.J. Leaf, UCLA
  2. Lonzo Ball, UCLA
  3. Rawle Alkins, Arizona
  4. Markelle Fultz, Washington
  5. Lauri Markannen, Arizona

Arguably the most talented class of freshmen to ever enter the Pac-12, UCLA’s Lonzo Ball takes the cake. (AP)

Now that we’re at the end of the year, it is time to revisit this list and see how everyone grades out with a full body of work.  The key to this whole premise is the value put into player efficiency, as this list would look much different if you instead used statistical volumes or per game averages. KenPom, as a salient example, ranks Fultz as the best player in the Pac-12 based on a combination of ability and usage rate. However, I’m going to stray from the Great KP here and stick with the previous formula for a couple reasons. First, while usage rate is certainly something to consider, the other names on this list are similar enough in usage to merit a reasonable comparison. Second, KenPom uses the entire season to compile his numbers while we’re sticking solely with Pac-12 play (which is still a bit noisy thanks to unbalanced schedules). This serves to clean up the unwieldy variables of non-conference scheduling and make for a fairer analysis. Here is how our quintet now ranks using the key criteria cross-referenced with defensive efficiency relative to team defensive performance. Read the rest of this entry »

Pac-12 Power Rankings: The Big Three and Everyone Else Edition

Posted by RJ Abeytia on March 1st, 2017

As we launch ourselves into March and the final weekend of Pac-12 play of the regular season, here are the final Power Rankings.

Thomas Welsh Wants Everyone to Recognize Where UCLA Stands (USA Today Images)

  1. UCLA– Nobody in the upper three did as much as the Bruins last weekend. Note that Arizona — which doesn’t really lose at the McKale Center, remember — was the first team in the past four games to post an offensive efficiency above the national average against UCLA’s improving defense.
  2. Oregon– The Ducks stood tough in the Bay Area last weekend thanks in large part to the second-best Pac-12 defense. Oregon plays aggressively (forcing a 20 percent turnover rate) yet cleanly with the second lowest FTA allowed rate in the conference.
  3. Arizona– Arizona, despite a tough home loss to the Bruins, continues to make its case as the most NCAA Tournament-ready team in the league. Why? First, the Wildcats play at the third-slowest pace in the Pac-12, and games always slow in postseason play. Secondly, Arizona does the best job in the conference in both getting to the foul line (37.4% FTA Rate) and making free throws when they get there (78%). Read the rest of this entry »

Pac-12 Power Rankings: Who Will Get the Fourth Bye?

Posted by RJ Abeytia on February 16th, 2017

With three weeks of league play left, both the the regular season title and the cherished final Pac-12 Tournament bye are still very much in play…

UCLA Basketball is Cool in LA Again (USA Today Images)

  1. Arizona– The Wildcats are experiencing their three talented freshmen (Lauri Markannen, Kobi Simmons and Rawle Alkins) running smack into the proverbial freshman wall. Despite that ongoing issue, they were still able to sweep the Bay Area schools without playing their best basketball. One of the biggest signs for optimism comes in the form of Chance Comanche, who has fortified Arizona’s post rotation by shooting 17-of-29 (59%) over the last two games.
  2. UCLA– How about a little love for Aaron Holiday? Upstaged by the arrival of superstar freshman Lonzo Ball, the sophomore guard has drastically improved upon what was a very good freshman campaign. He has already converted more three-pointers than all of last season (42) and has flipped his assist rate (24.4%) and turnover rates (21.5%) as well. He isn’t playing as much this season, but he is still a key cog in the Bruins’ devastating offensive machine.
  3. Oregon– The Ducks were about 15 minutes away from looking like the best team in the Pac-12. A furious comeback, however, orchestrated by UCLA’s Lonzo Ball proved that the conference is still up for grabs. As balanced as Oregon is across its rotation, the need for a closer is still an issue. Dillon Brooks has played that role very well for most of this season, but when he’s having an off game, the Ducks need another player to provide late-game production. Read the rest of this entry »

Weekly Pac-5: Unforced Errors

Posted by Adam Butler on February 3rd, 2017

The unforced error, most commonly quantified in tennis, is universally agreed upon as annoying. No matter your task, an error sustained but perhaps not earned, is peak frustration. As it translates to basketball, the non-steal turnover would seem to be among the most frustrating of unforced errors. This is the time of ball forfeiture that looks like an errant pass, a dribble off the foot, or an extra step and a travel. I imagine you cringed just reading that list.

Cal Outlasted Utah Last Night Partially Because of a Low 10 Turnovers (USA Today Images0

In this week’s Pac-5, we look at the Pac-12’s leaders in unforced errors. To quantify this, we’ll look at the percentage of a team’s turnovers that were not caused by theft. Here are the Pac-12’s team leaders in unforced errors:

  1. California, 64% of turnovers are non-steals – This is in fact a nationally bad number, ranking as the ninth-highest such ratio in college basketball. It might be particularly frustrating when you consider there are three seniors in Cal’s backcourt. There is, of course, also a freshman, Charlie Moore, who actually leads the Golden Bears in turnover rate. Furthermore, by volume, this must be wildly frustrating as the Bears play at the slowest tempo in the conference. That’s a lot of UFEs.
  2. Arizona, 60% – This one doesn’t hurt too bad when you consider the Wildcats commit a percentage of turnovers that is about at the national average.
  3. Washington, 58% – Considering that all these coughed-up opportunities could actually be Markelle Fultz jumpers? Also, Fultz owns the nation’s 28th-highest usage rate yet turns the ball over on just 14.9 percent of possessions.
  4. Oregon, 56% – Last season, Casey Benson had an outrageous handle at the point. This year he’s yielded those minutes to a Payton Pritchard, a freshman, who’s perhaps a greater scoring threat but something more of a turnover liability (as is Dillon Brooks, at 21%).
  5. Utah, 55% – We’re inching towards the national average (54%) so maybe this one isn’t as tough a pill to swallow as, for example, Cal? Too soon to mention those two teams in the same sentence?

NOT LISTED: Oregon State. The Beavers have the sixth highest turnover rate in the nation, which by itself is frustrating. They’re turning the ball over (stolen or otherwise) on nearly a quarter of their possessions.

Pac-12 Weekly Power Rankings: Vol. 3

Posted by Pac-12 Team on January 18th, 2017

The Pac-12 last season boasted the toughest road game in college basketball. During conference play, the league’s home teams won at a higher rate (71%) than any other conference in America. This season, Pac-12 home teams are winning at just a 59 percent rate. They say that conference titles are won on the road. How has your team fared in hostile territory?

Plenty to smile about for Dillon Brooks and Oregon lately. (Cole Elsasser/Emerald)

  1. Oregon (1) – The Ducks’ conference dominance continues. Since their dramatic, two-point victory over UCLA in the Pac-12 opener, Oregon has simply decimated their opponents. Oregon’s average margin of victory over the last four games is 26.5 points, a full 15 points higher than UCLA. Granted, the four teams the Ducks have played also have a combined 6-15 conference record, but at least they are taking care of business.
  2. UCLA (2) – How do we convince Thomas Welsh to get to the free throw line more often? That is the question that head coach Steve Alford should be asking himself. After shooting 75 percent from the charity stripe last season, the junior has yet to miss in his 24 attempts this year (leading to a subtle breakout season for the junior). Now if he could just average more than one freebie attempt every two games… Read the rest of this entry »
