Inside the ACC Numbers: Volume V

Posted by Brad Jenkins (@bradjenk) on February 15th, 2018

Here is the latest edition of our weekly view at the current ACC standings with a focus on which teams are playing better or worse than their conference records may indicate. We will also delve into some advanced metrics to share a few interesting notes on teams, statistics, and trends around the conference. This week we compare home versus road performance by each ACC school and showcase some extreme team offensive and defensive differences based on game location. Finally, we will forecast how the final ACC standings may look given current efficiency margins and what that may mean for teams’ ultimate postseason aspirations.

Note: All numbers are current for games played through Tuesday, February 13.

Current Standings

Louisville has clearly benefited from playing the softest ACC schedule to date, but the Cardinals’ remaining slate of games — three road trips plus home dates with North Carolina and Virginia — will be very challenging. David Padgett‘s team may need to win at least two of those five to solidify its inclusion in the NCAA Tournament. On the other hand, NC State has faced a brutal ACC schedule to this point but will have a much easier road down the stretch with only one remaining contest against a team with a winning ACC record.

Here is the latest edition of our weekly view at the current ACC standings with a focus on which teams are playing better or worse than their conference records may indicate. We will also delve into some advanced metrics to share a few interesting notes on teams, statistics and trends around the conference. This week we compare the importance of three-point shooting and free throw shooting to determine which has the most influence on winning games in the league this year. Finally, we will forecast how the final ACC standings may look given current efficiency margins, and what that may mean for teams’ ultimate postseason aspirations.

Note: All numbers are current for games played through Monday, February 5.

Current Standings

It’s interesting to consider the impact that conference schedule strength is having on the standings. Duke has clearly benefited from two games each against the worst teams in the league, Wake Forest and Pittsburgh. Aside from those four games, the Blue Devils are 3-3 in ACC play with a points per possession margin (PPM) of just 0.04. Among the five six-win teams in the conference, NC State and Florida State have faced a tougher slate than the others. After Saturday’s rematch against North Carolina, the Wolfpack will have played six games against the leagues best four teams, using the KenPom ratings. The upside of that, of course, is that Kevin Keatts’ growing squad will be no worse than .500 in the standings at that juncture, with a much easier road down the stretch. That bodes well for NC State to finish the season above both their norm in the standings as well as in PPM.

Here is the latest edition of our weekly view at the current ACC standings with a focus on which teams are playing better or worse than their conference records may indicate. We will also delve into some advanced metrics to share a few interesting notes on teams, statistics and trends around the conference. This week we consider which particular game statistics have the most influence on winning in the league this year. Finally, we will forecast how the final ACC standings may look given current efficiency margins, and what that may mean for teams’ ultimate postseason aspirations.

Note: All numbers are current for games played through Tuesday, January 30.

Current Standings

Virginia’s big win at Cameron Indoor Stadium on Saturday solidified the Cavaliers’ stranglehold at the top of the ACC standings. Tony Bennett‘s team now owns the league’s sixth-best offense to go along with the nation’s best defense  — the Cavaliers’ ACC defensive points per possession is an impressive 0.12 points better than next-place Louisville. Incredibly, that gap of 0.12 points is larger than the one between the Cardinals and 10th place Wake Forest. The numbers also reveal that Clemson’s record is quite a bit better than its point per possession margin (PPM) indicates. The main reason for this is that Brad Brownell‘s squad suddenly figured out how to win close games. After years of struggling to finish in the clutch, the Tigers are an impressive 4-1 this season in ACC contests decided by five points or fewer (or in overtime).

Inside the ACC Numbers: Volume II

Here is the latest edition of our weekly view at the current ACC standings with a focus on which teams are playing better or worse than their conference records may indicate. We will also delve into some advanced metrics to share a few interesting notes on teams, statistics and trends around the conference. This week we will look at the upcoming heavyweight match-up between Duke‘s potent offense and Virginia‘s stingy defensive unit. Finally, we will forecast how the final ACC standings may look given current efficiency margins, and what that may mean for teams’ ultimate postseason aspirations.

Note: All numbers are current for games played through Tuesday, January 23.

Current Standings

Virginia continues to steamroll through the ACC in dominant fashion. Since its one-point win over Boston College in their conference opener, the Cavaliers have pummeled seven straight ACC opponents by an average score of 66-49. The always effective pack-line defense reached a new level of excellence on Tuesday night when Virginia held Clemson to a meager 0.58 points per possession in a suffocating 61-36 win. At this point in the conference schedule, one extreme result can have a huge impact on the points per possession margin (PPM) rankings. For example, if we remove Notre Dame’s 88-58 blowout of N.C. State from the data set, the Irish (-.03) and Wolfpack (-.04) would have almost identical PPM during league play. The huge margin of victory in that single game is really the only thing that prevents almost perfect alignment between the current ACC standings and the PPM rankings.

Inside the ACC Numbers: Volume I

Posted by Brad Jenkins (@bradjenk) on January 18th, 2018

With approximately one-third of conference play now in the books, it’s time to take a look inside the ACC numbers. This is the first edition of our weekly view at the current ACC standings with a focus on which teams are playing better or worse than their conference records may initially indicate. We will also delve into some advanced metrics to share a few interesting notes on teams, statistics and trends around the conference. Finally, we will forecast how the final ACC standings may look given current efficiency margins, and what that may mean for teams’ ultimate postseason aspirations.

Note: All numbers are current for games played through Tuesday, January 16.

Current Standings

Boasting a large lead in points per possession margin (PPM) to go along with an undefeated record, Virginia clearly looks like the ACC’s top squad to date. And what is it with Josh Pastner? For the second consecutive year, Georgia Tech is off to a surprisingly good start in league play after a woeful non-conference performance. It isn’t odd to see some striking differences in win-loss records versus PPM performances this early in conference play, but that is not the case so far this year — the current PPM numbers match up pretty well with existing ACC standings.

Advanced Stat of the Week: 3FG% Defense

One of the things we like to look at early in league play is to identify which teams have experienced both good and bad fortune with their opponents’ performance. A useful metric for this is opponents’ three-point field goal percentage. Although defenses have some role to play in limiting wide-open looks, it is the offense that for the most part controls accuracy from deep. So when a team’s opponents are hitting threes at an extremely high or low rate over a small sample size, we can expect a regression to the mean to occur down the line. With this in mind, expect Virginia Tech’s defense to look better once its opponents cool down from three-point land, much like Duke’s defense has correspondingly improved lately. In their first three ACC contests (two losses), the Blue Devils were blitzed from deep to the tune of a combined 48.6 percent. But during its current three-game winning streak, Duke’s opponents have made just 32.9 percent from long-range. Likewise, expect Virginia’s vaunted defense to look a bit more vulnerable once the other side sinks a few more threes against them.

As a whole, the ACC is attempting more three-pointers than ever (37.1% 3FG rate in ACC play), but making fewer of them than a year ago. After a record-setting accuracy rate of 37.2 percent in 2017, the league is sinking 35.4 percent of its deep tries this conference season. That number is almost identical to the NCAA average of 35.1 percent nationally, so we should expect the ACC’s success rate from deep to remain pretty close to its current pace while individual team defensive three-point percentage normalizes.

Future Forecast

The above table shows predicted order of finish with final regular season records based on KenPom’s current win probabilities for each team. Also included are a few comparative rankings that are mentioned frequently when evaluating NCAA Tournament potential, as well as projections from two bracketology experts — ESPN‘s Joe Lunardi and CBS Sports‘ Jerry Palm. Note that while they project the field as if it was to be named tomorrow, we make our projections based on the final KenPom projected records.

It’s clear that the ACC is not as strong at the top as it was a year ago when the league offered six schools that were seeded #5 or higher. Interestingly, the ACC looks particularly strong in the RPI and normally that results in being awarded seeds that appear higher than deserved — using computer power ratings and opinion poll rankings. But with the Selection Committee’s stated desire to modernize its criteria for selection and seeding, will high RPI metrics still drive its decision-making? If the RPI’s influence is in fact lessened this year, it could hurt the NCAA’s chances for the bulging middle of the ACC — the five schools projected with either eight or nine wins.

Inside the ACC Numbers: Volume VIII – Final Edition

Posted by Brad Jenkins (@bradjenk) on March 7th, 2017

Here is the final edition of our weekly review of the current ACC standings and team performances where we focus on which teams are playing better or worse than their records indicate. Each week we delve into advanced metrics to reveal a few interesting teams, player statistics and trends. With the regular season now complete, we will look at which ACC teams performed better in the second half of league play and how that may impact the upcoming ACC Tournament. Finally, we forecast how the final ACC standings may look given current efficiency margins and what that means for each team’s postseason aspirations.

Note: All data is current for games played through Saturday, March 4.

Current Standings

North Carolina finished with an impressive two-game lead in the standings to edge out Louisville with the league’s top efficiency margin. Since the Cardinals finished as the #4 seed for this week’s ACC Tournament in Brooklyn, the two best teams in the conference landed on the same side of the bracket. The Tar Heels finish with the league’s top offense for the first time since 2009 — incidentally the last time North Carolina won the National Championship. This year, Roy Williams’ club used an outstanding offensive rebounding rate (42.5%) to overcome a modest shooting year — the Heels finished 10th in the league in effective field goal percentage (51.7%). Virginia reclaimed its status as the ACC’s best defensive squad, as Tony Bennett‘s teams have now finished as one of the ACC’s two best defenses in each of the last six seasons. Virginia’s pack line defense led the league in forcing turnovers (20.1%) and finished third in opponents’ effective field goal percentage (48.5%). Read the rest of this entry »

Inside the ACC Numbers: Volume VII

Posted by Brad Jenkins (@bradjenk) on March 3rd, 2017

Here is the latest edition of our weekly review of the current ACC standings and team performances where we focus on which teams are playing better or worse than their records indicate. Each week we delve into advanced metrics to reveal a few interesting teams, player statistics and trends. This week we will look at the how ACC teams have performed in the nail-biter games — conference games decided by one or two possessions. Finally, we forecast how the final ACC standings may look given current efficiency margins, and what that means for each team’s postseason aspirations.

Note: All data is current for games played through Wednesday, March 1.

Current Standings

Hats off to North Carolina for clinching at least a share of the ACC regular season title for the second straight season and for the eighth time in Roy Williams’ 14-year tenure at the school. The Tar Heels took advantage of a scheduling imbalance in their favor this year, with only three road games coming versus the top nine schools in the ACC standings. Despite being generally regarded as the ACC’s sixth best team in both the efficiency metrics and the national polls, Notre Dame sits alone in second place in the standings. With the Irish traveling to Louisville this weekend, though, the odds are against Mike Brey’s squad in catching the Heels. If all the home favorites win their games this weekend, Virginia Tech could rise all the way to the #5 seed in next week’s ACC Tournament, even with a likely negative points per possession margin. See below for how Buzz Williams’ guys have made this a legitimate possibility.

Here is the latest edition of our weekly review of the current ACC standings and team performances where we focus on which teams are playing better or worse than their records indicate. Each week we delve into advanced metrics to reveal a few interesting teams, player statistics and trends. This week we will look at the most extreme example of home court advantage in the ACC. Finally, we forecast how the final ACC standings may look given current efficiency margins, and what that means for each teams’ postseason aspirations.

Note: All data is current for games played through Wednesday, February 22.

Current Standings

Thanks to Wednesday’s home win over Louisville, North Carolina has now taken the lead in efficiency margin to go along with its two-game cushion in the standings. Efficiency margins confirm that the Tar Heels and the Cardinals are the two best teams in the league, so we should not be surprised if they meet again in the ACC Tournament championship game. If neither squad loses until March 11, one of the NCAA’s #1 seeds would probably be on the line that Saturday night. The standings match up well with efficiency at this point, with two notable exceptions – Virginia has played quite a bit better than its record indicates, while Virginia Tech appears to be very fortunate to be 8-7 in league play. Perhaps the hottest team in the league right now is Miami, as the Hurricanes have posted seven victories in their last nine outings.

Here is the latest edition of our weekly review of the current ACC standings and team performances where we focus on which teams are playing better or worse than their records indicate. Each week we delve into advanced metrics to reveal a few interesting teams, player statistics, and trends. This week we will compare how ACC teams defend the three-point line. Finally, we forecast how the final ACC standings may look given current efficiency margins, and what that means for teams’ postseason aspirations.

Note: All data is current for games played through Wednesday, February 15.

Current Standings

ACC teams continue to be bunched close together at the top of the standings as well as in efficiency margins — the schools that have played easier conference schedules look better in points per possession. Things are about to even out with respect to schedule difficulty, however, among the league’s top six squads. Here’s what each of those schools has remaining against one another:

  • North Carolina (4 games) – Virginia, Louisville, @ Virginia, Duke
  • Louisville (2) – @ North Carolina, Notre Dame
  • Duke (2) – Florida State, @ North Carolina
  • Virginia (2) – @ North Carolina, North Carolina
  • Florida State (1) – @ Duke
  • Notre Dame (1) – @ Louisville

North Carolina clearly has the toughest remaining slate, but at least three of those four difficult contests will come in the Smith Center where the Tar Heels have yet to taste defeat this season. Florida State and Notre Dame have the easiest closing batch of games, with just one each against the rest of the top tier. According to KenPom, North Carolina’s conference schedule has been about four points per game easier than those faced by the Seminoles and Irish. That gap is about to shrink considerably, and by year end we would expect ACC strength of schedule to essentially even out among the top six contenders. Read the rest of this entry »

Inside the ACC Numbers: Volume IV

Posted by Brad Jenkins (@bradjenk) on February 10th, 2017

Here is the latest edition of our weekly review of the current ACC standings and team performances where we focus on which teams are playing better or worse than their records indicate. Each week we delve into advanced metrics to reveal a few interesting teams, player statistics and trends. This week we will compare some ACC player usage rates with offensive efficiency, seeing where some teams might benefit from a shift in possessions. Finally, we forecast how the final ACC standings may look given current efficiency margins, and what that means for teams’ postseason aspirations.

Note: All data is current for games played through Wednesday, February 8.

Current Standings

Syracuse‘s rise up the league standings is the story of the week. Jim Boeheim‘s club has now won five straight games by 10 points or fewer. The Orange’s close game effectiveness is why their record outshines a relatively low efficiency margin. For similar reasons, North Carolina continues to top the league standings despite trailing Louisville and Virginia in per possession performance. Florida State‘s efficiency margin now lines up nicely with its record after blasting its last three opponents by an average of 30 points per game.
