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.

Ex-financial adviser gets 4 years in federal prison for defrauding Tim Duncan

SAN ANTONIO (AP) An ex-financial adviser to retired San Antonio Spurs player Tim Duncan has been sentenced to four years in federal prison for defrauding the former NBA star of millions of dollars.

Federal prosecutors say 49-year-old Charles Banks of Atlanta was sentenced during a court hearing Wednesday in San Antonio.

A judge also ordered Banks to pay $7.5 million in restitution.

Banks had pleaded guilty in April to one count of wire fraud.

Investigators say Banks manipulated Duncan -who retired last year after five NBA championships with the Spurs – into guaranteeing payment of a $6 million debt related to a merchandising business.

Prosecutors say Banks failed to disclose commissions and loans he received in the deal.

Banks is set to report to federal prison as early as Aug. 28.

EL SEGUNDO, Calif. (AP) — The Los Angeles Lakers have exercised their $1.3 million contract option on guard David Nwaba for the upcoming season.

The Lakers announced the move Wednesday.

Nwaba earned a job with the Lakers after they called him up from their D-League affiliate on Feb. 28. The rookie averaged 6.0 points and 3.2 rebounds per game while impressing Luke Walton’s coaching staff with his hustle and defensive play.

The Lakers signed him to a new contract with a multi-year component just three weeks after his NBA debut.

Nwaba is a local product, attending University High School in West Los Angeles and Santa Monica College before finishing his college career at Cal Poly.

HAYWARD, Calif. (AP) — Two-time NBA MVP Stephen Curry is set to test his golf game against the pros.

The Web.com Tour said Wednesday that Curry, coming off his second NBA championship with the Golden State Warriors, will play in the Ellie Mae Classic at TPC Stonebrae on Aug. 3-6.

It’ll be the first PGA Tour-sanctioned event for Curry, who has competed in various celebrity events and pro-ams. The top 25 on Web.com Tour’s regular-season money list will earn PGA Tour cards.

Curry will maintain his amateur status, competing on an unrestricted sponsor exemption in the event that benefits the Warriors Community Foundation.

Hall of Fame receiver Jerry Rice played in the event in 2011 and 2012. He missed the cut in 2011 with rounds of 83 and 76 and withdrew in 2012 after playing 27 holes in 23 over.

Also Wednesday, Nissan’s upscale Infiniti brand announced that Curry would be its new global brand ambassador. The point guard will be featured in ads for the Q50 sports sedan beginning this summer.

Report: Clippers never committed to offer Chris Paul five-year max contract

The Clippers projected to be able to offer Chris Paul a five-year, $201 million contract that would have culminated with a $46 million salary in his final season.

Did they offer that much before sending him to the Rockets?

Just as one side is trying to pin all the Clippers’ problems on Doc Rivers and Austin Rivers, the Clippers surely want to spin Paul’s exit to another way – that they shrewdly chose when to part ways rather than that they lost the best player in franchise history due to nepotism.

David Aldridge of NBA.com:

Ramona Shelburne of ESPN:

If Paul really wanted that five-year max, he could have pushed harder for it by bringing counter offers to the Clippers in July rather than engineering his way to Houston before free agency even began.

Would the Clippers have eventually relented and offered the five-year max? We can never know for certain.

But it’s pretty clear why the Clippers would want this version out there. Accurate or not, it makes them seem far more on top of things and is less likely to taint them with free agents they covet in 2018.
