Here’s another 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 evaluate how ACC teams are performing on the road versus how well they play in the cozy confines of their home gyms. Finally, we will forecast how the final league 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 5.

Current Standings

The ACC has a top tier of four teams in efficiency margin with Virginia still comfortably leading the way. It will be interesting to see how the ACC’s upcoming schedule shakes things up. The Cavaliers start a pivotal three-day stretch with Saturday’s home game with Duke, followed by a quick turnaround trip to Chapel Hill to take on red-hot North Carolina team on Monday night. Louisville is also staring at a difficult two-game slate over the next seven days — the Cardinals visit Florida State on Saturday before taking on Duke at home on Tuesday evening. Syracuse has been the most fortunate squad in the first half of ACC play this season. At 7-3, Jim Boeheim’s team is already four games above .500 despite barely outscoring its opponents. Looking at the bottom of the conference, Wake Forest has been the league’s worst performing team by a wide margin, but the Demon Deacons have managed to post a similar record to the five schools directly above them. That’s because Wake Forest has gone 2-1 in ACC games that were decided by four points or fewer. In their other seven outings, the Deacs have been beaten by double-figures.

Advanced Statistic of the Week: Home Sweet Home in the ACC

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 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 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.

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.

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. We are at the halfway point of conference play, so we now have more data points to look at – numbers which reveal some interesting trends. This week we will look at home versus away results for each team in the league so far this year. 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 1.

Current Standings

Despite suffering some recent injuries to its backcourt, Louisville looks like the ACC’s best squad at the halfway point in conference action. The Cardinals’ efficiency numbers are certainly boosted by the 55-point shellacking that they put on Pittsburgh, but remember that North Carolina and Duke also put together dominant one-game performances against NC State and Georgia Tech, respectively – and they have played softer league schedules to date. Further down the standings we see some teams with records that do not correspond with their per possession performance. For instance, Virginia Tech may be 5-5 in the ACC standings but its overall play from an efficiency standpoint has only been slightly better than that of Boston College (against comparable schedules). Keep on eye on Clemson – the 3-6 Tigers have now won two in a row and four of their losses have come by five points or fewer or in overtime. North Carolina may have faced the league’s easiest slate so far, but that’s about to change. The Tar Heels have only faced two ACC foes with winning records so far, but their last eight contests will feature six such squads.

This is the second part of a review of home court trends in the ACC. In Part I that published yesterday, we looked at overall home court winning percentage in ACC conference games over the last 15 years. Today we will look at the outcomes when ACC teams play each other twice in the regular season. In the days before major conference expansion, every league team played the others twice each year, a convention that ended when the ACC reached 11 members in 2005. The conference has since played an unbalanced schedule that features several home-and-home scenarios but mostly consists of one-time match-ups. 

As the above graph shows, we reviewed 312 double-meetings between ACC teams over the last 10 years. We broke the data into four discernible outcomes — sweeps by better and worse teams (as determined by KenPom‘s final rankings), and splits where home or away teams won both games. The data shows that there were 188 sweeps and 124 splits over the 10-year sample. The better team won both games 53.5 percent of the time; teams splitting games by defending their home floors occurred 32.7 percent of the time; while sweeps from the worse team and splits with the road teams winning made up the remaining 21.8 percent — on average, about twice per season.

Through the first two weeks of conference play, ACC teams are an impressive 21-7 (.750) at home, flying in the face of a national trend. Over the past 15 years, there has been a slight but noticeable drop in home court advantage in college basketball. From 2002-09, teams won their conference home games at a rate of about 62 percent. It dropped to nearly 61 percent for the next four seasons from 2010-13, and then declined a bit further to approximately 60 percent over the last three campaigns. How has it looked in the ACC over the same span? This is the first of a two-part examination of home court advantage in the ACC.

As you can see above, the ACC at just over 63 percent ranks in the middle of the pack of the six power leagues over the last 15 seasons at defending home turf. Interestingly enough, home court advantage in the major conferences has not been as volatile as the nation overall. Read the rest of this entry »

Here is the latest edition of our weekly look at the current ACC standings and team performances, focusing on which teams are playing better or worse than their records indicate. Each week we also delve into some advanced metrics to find a few interesting teams or player stats and trends. This week we examine home court advantage within the league. Finally, we will forecast how the final standings may look and what that means for ACC schools’ postseason aspirations.

Current StandingsDespite Monday night’s defeat at Louisville, North Carolina is still the ACC’s best team in both the standings and in points per possession (PPP) margin. Interestingly, even though much has been made of Duke’s struggles (the Blue Devils are currently in eighth place), it has outperformed every team but one above them in the standings. It appears that Mike Krzyzewski’s team’s inability to win the close ones is the real issue that must be fixed — Duke has lost all three of its contests that were decided by five points or fewer. Conversely, Clemson and Pittsburgh have each benefited by winning all three of their five-point or fewer margin games. Looking further down the standings, we see that N.C. State and Georgia Tech have basically performed at a level equal to Florida State and better than Virginia Tech, but they trail both of those teams in the current standings by at least two games. Heading into the back nine of conference play, future opponents should consider themselves warned — the Wolfpack and Yellow Jackets may barely rank above the likes of Wake Forest and Boston College in the standings, but they are both significantly better than the leagues’ worst two teams.

N.C. State is 15-4 overall and 4-2 in the ACC and has as much potential of any team in the conference this season. Led by powerful big men and electric wing players, the Wolfpack got their signature win when they knocked off Duke in the RBC Center a couple of weeks ago. Unfortunately, Mark Gottfried‘s crew has also picked up two very telling losses that speak to the existence of home court advantage in the ACC more than the Wolfpack’s inconsistent play.

NC State currently has a 1-3 record on the road with two of those losses coming in their last three games. Losses at Maryland and Wake Forest look bad by themselves but when looking at them next to their lone road win — a five-point win at Boston College — the trend becomes upsetting. By this time of the season they have shed the “young team” moniker and their big-minute freshmen have actually been the bright spots for this team away from home. In their three ACC away games, the Wolfpack are shooting 43 percent from the field, down from their outstanding 51 percent total for the season. This is where the issue has been as Gottfried’s team is holding opponents relatively in check on defense with a negligible difference between home and away (41 percent on the road, 40 percent overall). Typically, teams that rely on their defense and scoring inside do well on the road (see Florida State last year), while teams that rely on shooting the ball well from the perimeter inevitably falter in hostile situations.

Conference play has started and it is a glorious thing. While non-conference play has its charms (who doesn’t love to see heavyweights go at it?), conference play has a special allure. Games are exciting when there is history, and that’s what conferences offer: a history of rivalries and past meetings that add a little bit of spice to each new meeting. And while old wounds may ache, it’s the new ones that sting: The best part of conference play is the home-and-away series; to better understand  the meaning of Duke and Ohio State’s close scrapes this past week, we need to understand home cooking.

Home Cooking, the Way Mom Used To Do...

“Home cooking.” When we talk basketball, we understand that this phrase is a euphemism for home-court advantage, a catch-all for the widely-discussed yet still mysterious phenomenon. Teams win more when they play on their home court. This is a fact. It’s the “why” that’s much more complicated, and there are many explanations. The “home cooking” euphemism itself is a partial explanation, metonymy for all the comforts of home: sleeping better in your own bed, being able to stick to your own routine, and, of course, literally getting to eat a home-cooked meal. Taken altogether, the psychological benefits of these things (coupled with the converse disadvantage of opponents lacking these things) is supposed to account for the edge that comes with playing at home. Of course, savvier or maybe just more cynical people hear “home cooking” and their minds turn to matters more sinister than mom’s meatloaf. “Home cooking” to these folks means referee bias in favor of the home team. The innocent and idealistic amongst us shudder at the thought, but the harsh reality is that referee bias is real.

Kyle Anderson and David Pierce in a 2009 article published in The Journal of Sports Sciences outline a series of systematic referee biases in men’s college basketball. In addition to being more likely to call fouls on the team with the lead and on the team with the fewest fouls, referees really do call more fouls on the visiting team. Also, oddly enough, these effects are more pronounced when the game is on national television. But, of course, home court advantage is bigger than just getting a few fouls going in favor of the home team, isn’t it?
