NBA referees are biased

Leave a comment

Yes, NBA referees favor stars and swallow their whistles late in games.

That has been the conventional wisdom from fans for years, with the NBA of course denying that. But that is the beauty of the MIT Sloan Sports Analytics Conference — those “geeks” that fans deride for their fancy stats (“You can’t measure heart, man!”) can turn their attention and math skills on to issues like the refs.

And prove the fans were right. Kevin Arnovitz (and Henry Abbott) from TrueHoop is there (with fantastic coverage of the entire fascinating event) and breaks it down:

The study compared how likely officials were to call loose ball fouls on stars compared to non-star NBA players they were contesting in loose ball foul situations. The results were found over a three-year study in which 1.5 million plays were examined in 3,500 plus games. “Star” criteria was based on players’ MVP votes. The results: 42 percent of loose balls fouls called on stars in “regular” situation compared to 57 percent of the time on non-stars in plays. The numbers show a much more dramatic shift, favoring the star players when they are in “foul” trouble with only 28 percent of foul calls being called on them, a huge drop from the earlier 42 percent.

The other study involving the NBA involved a look at subjective calls (offensive fouls, traveling, double dribble, etc.) being made compared to non-subjective calls (kick ball, 24-second violation, etc.) over the course of the game. The tendency to want to let the players decide the game in close as well as late game situations showed itself once again in the form of omission bias, with the rate of calls falling dramatically from the first half to the second half. Another even sharper drop in subjective calls was apparent in overtime games with the subjective or “judgment” calls. The non-subjective call rates remained very level over those time spans.

Hey fans — the math guys are not just good at proving that the refs have issues. Those advanced stats you deride, they are right most of the time, too. Just a little something to think about.

Rockets were draining threes in the first half against Warriors in Game 6

The Rockets were feeling it the first half in Game 6.

Playing with an energy the Warriors lacked at least in the first quarter), Houston defended well, pushed the ball in transition, and then they just drained three after three after three.

Eric Gordon started 4-of-4 from three and the team was 11-of-22 in the first half, which made up for the 11 turnovers and had them up 17 at one point and ahead by 10 after the first half.

Warriors’ Andre Iguodala out for Game 6

Steve Kerr has been searching for a couple of games now for his fifth guy.

With Andre Iguodala out there is no Death/Hamptons 5 lineup and Kerr is looking for a fifth guy to partner with his four All-Stars. Kevon Looney is starting, Jordan Bell is showing potential but also makes some rookie plays, Nick Young has been bad enough that Kerr trusted Quin Cook more at the end of the last game (and Cook missed his looks).

Kerr is going to have to keep searching for a guy in Game 6 because Iguodala is out again.

The Warriors are not the team heading into Game 6 with the most significant injury woes, the Rockets are without Chris Paul. That and the fact the Warriors’ backs are against the wall is the reason they are heavy favorites in Game 6.

However, the Warriors have not been the same without Iguodala. He is a playmaker who can control the ball and settle things down, makes the right decision, get the player and ball movement the Warriors have strayed too much from back, plus is one of their best defenders on James Harden. Nobody else on the roster can do that.

And if Game 6 gets tight late, the Warriors are going to miss those skills. As they have in the last two games.

Marcus Smart on Game 7: ‘It’s not going to be pretty’

Game 7s are not pretty basketball. Everyone is tight, shots clank off the front of the rim, and players tend to think rather than just react, sucking the flow out of the game. It’s a game for grinders.

Marcus Smart is good with that, and he told Chris Forsberg of ESPN the team is preparing for this style.

“It’s not going to be pretty. You got to be able to get down and get dirty. You can’t go out and try to look pretty. You have to be ready for a dogfight. We got to be ready to come up with our nose bloodied. We got to be ready to come out with our mouth bloodied. We have to come out ready to fight.”

If Boston is going to win this game, they will do so with the physical, smart, and unrelenting defense that carried them all season. That’s their grit. Without Kevin Love (out with a concussion) the Celtics have one less scorer to worry about, but things do not necessarily get dramatically easier — LeBron James is going to get his buckets, but can the Celtics keep George Hill, Kyle Korver, J.R. Smith and the rest of the role players from helping out with big nights of their own.

Which one of these teams is better positioned to win a grinding, sloppy game? Who is willing to dive on the floor and give that little extra effort? A case can be made either way, but Sunday night will decide it.

Report: Warriors’ Patrick McCaw cleared, will be available for Game 6

We haven’t seen Golden State’s Patrick McCaw on an NBA court since March 31, when he was undercut by Sacramento’s Vince Carter and took an ugly, nasty spill.

McCaw is finally cleared by the team doctors and will be active on Saturday night for Game 6 against Houston, reports Shams Charania of The Vertical at Yahoo Sports.

The Golden State Warriors are planning to activate swingman Patrick McCaw for Game 6 of the Western Conference finals against the Houston Rockets on Saturday night, league sources told Yahoo Sports.

McCaw, on paper, would help the Warriors — he’s a 6’5″ switchable defender who can provide some offense in transition. That’s especially true if Andre Iguodala is out for Game 6 (his status is a game-time decision). McCaw played about 17 minutes a night for the Warriors during the regular season.

However, the idea of taking a second-year player who has not been on a court in six weeks and throwing him into Game 6 of the Western Conference Finals — a win-or-go-fishing game for Golden State — is risky, at best. Don’t expect him to get on the court unless this is a blowout.
