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.

Spurs to give Tim Duncan, Manu Ginobili Friday night off in Denver

The Spurs are 12-3 and comfortably in second place in the West, they have the best defense in the NBA allowing just 93.8 points per 100 possessions, and they have a top-10 offense to go with it.

So, time to start making sure guys are rested.

That is the first night of a back-to-back, with former Spurs’ assistant coach Mike Budenholzer and his Atlanta Hawks coming to San Antonio on Saturday. Popovich is saving his two veterans for that game.

Duncan and Ginobili have looked like they found the fountain of youth this season. Duncan is taking on less of the offense but has been very efficient in those moments. Ginobili has the impact he did a few years back in his bench role.

What Gregg Popovich cares about is them playing like that come the postseason. So they will rest on Friday.

Ray Allen is retired-ish, but he’ll always be running through screens – in our mind and in this video.

Celtics draft pick Marcus Thornton gets beer dumped on head during Australian game (video)

The Celtics drafted Marcus Thornton with No. 45 pick in the 2015 NBA draft. That essentially entitled him to the required tender – a one-year contract offer, surely unguaranteed at the minimum.

Thornton rejected that, which is almost always a mistake.

Rejecting the tender is a favor to the drafting team, which gets to keep the player’s exclusive rights for a year. If Thornton tries to join the NBA now, he’s stuck negotiating with only the Celtics.

By accepting the tender, the player typically gets one of two outcomes. He either plays on that contract and draws an NBA salary or he gets waived. But even getting waived is better than rejecting the tender, because at least the player becomes a free agent and can negotiate with any team.

Players who reject the tender go to another league and play for less money. In Thornton’s case, that mean Australia.

How’s that going?

(Almost) never reject the required tender as a second-round pick.

Byron Scott says they just have to get Kobe Bryant better looks

Kobe Bryant is averaging 15.2 points a game at age 37. It’s just taking him 16.4 shots per game to get there. After his 1-of-14 shooting performance against the Warriors the other night — with too much isolation and too many plays run just for him — there has been a lot of talk about his shot. With reason, this is his shot chart so far this season.

So what do the Lakers’ do? Get Kobe to shoot less and get the ball in the hands of the young stars they supposed to be developing more? Nah.

They just need to get Kobe better looks, Scott told the Los Angeles Times.

“I know his mentality is that he can still play in this league,” Scott said. “And we feel the same way….

“Obviously he’s struggling right now with his shot, and I think everybody can see that,” Scott said. “So it’s trying to get him in better position to be able to have an opportunity to knock those shots down on a consistent basis. That’s No. 1.

“I don’t know if it’s his legs. I don’t think so. Again, our conversations are pretty blunt. … He tells me when he is tired and he tells me when he’s not tired. And the last few days, he said he feels great. So, I don’t think it’s a matter of him being tired or his legs being tired. I think it’s a matter of his timing being a little off.”

Yes, how could it be his legs? It’s not like he’s a 37-year-old with more than 55,000 NBA minutes played, and coming off an Achilles rupture and major knee surgery.

Honestly, I hope the Lakers and Kobe find a balance soon, because they have become just hard to watch. And I don’t want Kobe to go out this way.
