Orlando's Stan Van Gundy shouts during an NBA playoff basketball game in Indianapolis

Stan Van Gundy questions integrity of advanced statistical data at MIT Sloan Sports Analytics Conference

30 Comments

BOSTON — Stan Van Gundy appeared as part of the basketball analytics panel at the MIT Sloan Sports Analytics Conference on Friday, and while he isn’t opposed to coaches integrating advanced statistical data into their day-to-day operations, he was concerned about the particulars of how the data is acquired, and who, exactly, is responsible for sorting it all out.

Van Gundy posed legitimate questions that would theoretically need to be addressed before the basketball purists at the NBA level take the data as gospel, and making sure that whoever is identifying certain play types and quantifying them knows basketball, and is doing that job to the specifications of a particular head coach.

“I don’t trust most of it,” Van Gundy said, beginning an exquisite rant on the topic. “I read some of the stuff that people write on ESPN.com, you know, I’ll read stats on pick and roll defense and stuff that came off Synergy or somewhere else — I don’t know who the hell is recording that information!”

“I read a thing in the playoffs last year that said that New York isolated like 17 percent of the time,” he continued. “I’m watching their games, they isolate half of the time, at least. So I don’t know who’s recording that. If there’s a pick and roll, and they throw it back to Carmelo and he holds the ball and isolates for eight seconds, that’s a pick and roll play, not an isolation? And a lot of pick and roll stuff … you know, I read a thing today from ESPN the Magazine on Paul George being the best pick and roll defender in the league on the ball handler. Look, a lot of pick and rolls … there’s pick and rolls designed to score, and there’s pick and rolls you run to get into something else. If you’re recording it and you’re treating those two things the same, then you don’t know what you’re doing.”

Van Gundy really does like the additional available data — he just needs to be able to trust that whoever is compiling it has the same standards basketball-wise that he does. Ironically enough, I overheard a statistician type at one of the panel discussions explaining to a colleague that of course he watches games — but only to enhance his data set.

“I mean, I do watch the games,” this person said, “to to try to pick up on some things that maybe my numbers aren’t catching.”

This is obviously completely backwards, and as far as Van Gundy is concerned, there’s simply no substitution for the eye test.

“To me, I think that a lot of the analytic stuff can be very useful, but if you’re using that in place of sitting down and watching film yourself and seeing what’s going on, you’re making a big mistake,” Van Gundy said. “And I don’t want to offend anybody, but I think one of the problems with analytics — I think it’s good; I used it, I love looking at it — but one of the problems is, there are a lot of people in a lot of organizations who don’t know the game, who all they know is analytics and as a result, that’s what they rely on. And they will use that to supersede what guys like us see with our eyes. And I think that’s a major mistake. There’s no substitute for watching film over and over and over again, and the only numbers I trust are the ones that my people believe.”

Van Gundy isn’t alone in his hesitance, and it will take some time before everyone trusts the way that the bulk of the data is quantified and labeled for mass consumption.

The Cleveland Cavaliers have signed forward Derrick Williams to a second 10-day contract.

The NBA champions have been impressed with Williams, a former No. 2 overall pick, and it’s likely they will sign him for the remainder of the season when his current contract expires. The Cavs announced Wednesday they signed Williams again. He has averaged 9.8 points and 3.0 rebounds in 22 minutes for the Cavs, who have been bringing him off their bench with their second unit.

Before signing as a free agent with Cleveland on Feb. 9, Williams played for Miami this season before being released.

The Cavs returned from the All-Star break Wednesday and will practice before hosting the New York Knicks on Thursday, just a few hours after the trade deadline.

Hornets’ Miles Plumlee out at least two weeks with leg injury

The Hornets are essentially two different teams with and without Cody Zeller.

They’re 22-17 when he plays and 2-15 when he doesn’t. They play at a 62-win pace with him on the floor and a 29-win pace when he sits.

So, with Zeller banged up, Charlotte traded for Miles Plumee. But Plumlee hasn’t provided much, just 3.2 points and 3.8 rebounds in 13.4 minutes per game in five contests.

And now he’ll add even less.

Hornets release:

The Charlotte Hornets announced today that center Miles Plumlee underwent a Magnetic Resonance Image (MRI), which revealed a second-degree calf strain in his right leg. Plumlee will be out for Charlotte’s game tomorrow at Detroit and will be re-evaluated in two weeks.

The Hornets incurred significant long-term costs ($37.5 million over the next three years) to use Plumlee as a short-term bandage. Without him providing even that, this situation looks bleak.

Depending on Zeller’s health, this could turn Charlotte — 2.5 games and three teams out of playoff position — into sellers before the trade deadline. At minimum, it makes the Hornets less likely to buy.

Report: Bulls pushing to trade for 76ers’ Jahlil Okafor

The Bulls reportedly reached out to the 76ers about Jahlil Okafor a few weeks ago.

After unfulfilled intrigue and maybe a trade that fell through, Okafor remains in Philadelphia. And Chicago apparently still wants him.

Adrian Wojnarowski of Yahoo Sports:

As constituted, the Bulls already have a few interior bigs: Robin Lopez, Taj Gibson and Cristiano Felicio. But one or more could go in an Okafor trade or another deal.

Okafor would make the Chicago younger, confusing its direction with Jimmy Butler and Dwyane Wade already in place.

Perhaps, the Bulls are pushing for a trade only because they’re offering so little. Okafor’s low-post game offers intrigue. At the right price, he’d be worth adding, no matter the fit and direction presented.

Maybe the 76ers don’t go for a lowball offer, but that’d be worth trying considering their center logjam with Joel Embiid, Nerlens Noel and Jahlil Okafor. Otherwise, Chicago ought to tread carefully when pursuing Okafor.

Report: 76ers trading Ersan Ilyasova to Hawks for Tiago Splitter, picks

The 76ers have played like a 64-win team when Joel Embiid and Ersan Ilyasova share the court and a 20-win team otherwise, using data from nbawowy!.

That’s helpful for Philadelphia, which is learning what type of player — a stretch four — works best with its franchise player.

But the Hawks can use more than just a lesson in the idea of Ersan Ilyasova. They can use actual Ersan Ilyasova.

And Atlanta will get him.

Adrian Wojnarowski of Yahoo Sports:

Jake Fischer of Sports Illustrated:

Atlanta stills sound intent on keeping Paul Millsap, so Ilyasova will likely back him up. Ilyasova should work particularly well with Dwight Howard, whose interior play was a key factor in ushering in this stretch-four era by covering for the lighter power forward next to him.

In the last 21 months, Ilyasova has been traded five times: from the Bucks to the Pistons to the Magic to the Thunder to the 76ers and now to the Hawks. They can probably count on the veteran to settle in quickly as they try to improve their position in the middle of the Eastern Conference playoff race. Atlanta is fifth, closer to third than sixth.

Both Ilyasova and Splitter have expiring contracts. The advantage of Splitter, who has missed the Hawks’ last 90 games, is that his full compensation counts toward the floor apparently without Philadelphia actually having to play all of his salary.

Plus, those picks could help the 76ers in a season where they can win something meaningful — like the Hawks have decided this season is for them.
