‘Hot Hand’ may exist after all, and data shows players like J.R. Smith believe in it

21 Comments

BOSTON — It doesn’t take an MIT graduate student to tell you that J.R. Smith is among the many players in the league who believe in the “Hot Hand” theory, which is essentially the notion that if you’ve made a few shots in a row, you’re shooting the next one — regardless of the quality of that shot — because of a belief that you’re now in some kind of zone.

Historical research has shown that this type of streak shooting simply doesn’t exist — think of it like a coin flip or a roulette wheel, where what happened on the previous toss or spin has no bearing on the outcome of the very next turn.

But new research presented at the MIT Sloan Sports Analytics Conference shows that the Hot Hand does indeed exist, and that there is a statistical likelihood of a player hitting his next shot after making a few in a row — once you adjust for things like difficulty, range, and the proximity of the nearest defender that hasn’t been possible to quantify until now.

The SportVU tracking cameras that have been installed in all 29 NBA arenas log all of this data, so when you put this information into a complex mathematical equation, what you get is a small statistical bump (a little more than one percent) in the likelihood of a player making his next shot after he’s hit three or four straight.

The most important factor here seems to be the “heat check,” where a player will launch increasingly difficult shots that have a very small percentage of going in once one of these shooting streaks has started. It could be a pull-up three in transition, or a wild turn-around jumper over a long defender, but these types of shots not only end a player’s current run of hot shooting, they’re also detrimental to his team’s overall success on a given possession.

The conclusion of the study found that players believe in the Hot Hand and act accordingly: When they believe they’re hot, they take shots from further away, defenders cover them more closely, they are more likely to take their team’s next shot, and they take shots that are more difficult than normal. The aforementioned J.R. Smith, for example, was found to take his team’s next shot more than 50 percent of the time when he’s made four of his last five.

Statistically, it was shown that players make a higher percentage of shots after hitting a few consecutively when adjusting for these factors. Teams could theoretically use this data to educate players by informing them that yes, when you feel like you’re hot, there’s something real associated with that — just don’t go forcing a horrendous shot the very next time you touch the ball because of it.

Lakers hire Kardashian trainer Gunnar Peterson

LOS ANGELES (AP) A celebrity trainer known for getting the Kardashian clan into shape is going to work for the Los Angeles Lakers.

Gunnar Peterson is the Lakers’ new director of strength and endurance training, the team announced Wednesday.

Peterson has been a favorite trainer among entertainers and athletes for many years while running a well-regarded private gym in Beverly Hills. His client list has included Sylvester Stallone, Halle Berry, Ben Affleck, Jennifer Lopez, Sofia Vergara and Pete Sampras, along with most of the Kardashian family.

Peterson will develop a strength and conditioning program for the Lakers, general manager Rob Pelinka says.

The 16-time NBA champion franchise has replaced several key members of its internal staff since Magic Johnson and Pelinka assumed control of basketball operations earlier this year.

Report: Bucks interested in Cavaliers GM David Griffin

The Magic hired Jeff Weltman, and the Hawks are reportedly close to hiring Travis Schlenk.

In other words, Cavaliers general manager David Griffin – who’s still without a contract for next season – lost his leverage with other teams.

But to the rescue are the Bucks, who will not necessarily promote assistant general manager Justin Zanik to replace Orland-bound general manager John Hammond.

Joe Vardon of Cleveland.com:

Multiple sources told cleveland.com that the Bucks, who lost general manager John Hammond to the Orlando Magic this week, have interest in Griffin, 47.

Griffin and Cavs owner Dan Gilbert have spoken about continuing their partnership in recent days, sources said, though no agreement was reached.

I still think Griffin stays in Cleveland. He helped assemble a championship contender, and he has LeBron Jamesendorsement. Plus, the Cavaliers can afford him.

But whomever gets the Milwaukee job will inherit a roster stocked with promising young talent like Giannis Antetokounmpo, Khris Middleton, Jabari Parker, Malcolm Brogdon and Thon Maker. The Bucks wouldn’t be a bad fallback option for Griffin – if he can’t use them to get a deal with the Cavs.

Cavaliers coach Tyronn Lue: Celtics’ sets harder to defend than Warriors’

With the Cavaliers up 3-1 on the Celtics in the Eastern Conference finals, most basketball observers are focused on Cavs-Warriors III in the NBA Finals.

But Cleveland coach Tyronn Lue is more concerned with Boston, which scored surprisingly well in Games 3 and 4 after losing Isaiah Thomas to injury.

Lue, via Dave McMenamin of ESPN:

“I don’t even think about them,” Lue said of the Warriors to a small group of traveling Cleveland beat writers following the Cavs’ Game 4 win on Tuesday. “We’re just focused on Boston. The stuff they’re running, it’s harder to defend than Golden State’s [offense] for me, as far as the actions and all the running around and all the guys who are making all the plays, so it’s a totally different thing.”

Wait, the Isaiah Thomas-less 53-win Celtics are harder to defend than the Kevin Durant-supercharged 67-win Warriors? Come again, Coach?

“Like, they hit the post, Golden State runs splits and all that stuff, but these guys are running all kinds of s—,” Lue said of Boston coach Brad Stevens’ schemes. “I’ll be like, ‘F—.’ They’re running all kinds of s—, man. And Brad’s got them moving and cutting and playing with pace, and everybody is a threat. It’s tough, you know, it’s tough.”

I think Lue means in a very specific way – getting his players into proper position. And in that regard he might be right.

I also think the Warriors will take this in the broadest, most offensive way possible. That’s just the nature of this rivalry.

Without Thomas, Stevens has been forced to diversify Boston’s offense. The Cavaliers, who prepared for a very different scheme, were caught off guard and are adjusting on the fly.

That’s a real challenge. But framing it as the central issue sells Golden State short.

Even if it’s harder for Lue to get his players into proper position against the Celtics, the Warriors’ surplus talent – including Stephen Curry, Kevin Durant, Klay Thompson and Draymond Green – more than makes up for it. And it’s not as if Golden State runs a basic scheme.

So why did Lue say this?

He didn’t think the travelling Cleveland beat writers would publish his candid remarks? He didn’t convey his thoughts clearly? He naively didn’t consider how this would motivate the Warriors? All are plausible.

Another theory: Lue is trying to plant a seed that acting Golden State coach Mike Brown, whose known (fairly or not) for his simplistic offensive schemes, is holding back the Warriors. If Steve Kerr doesn’t return, resentment of Brown is one of the few things that could tear apart a dominant Golden State team.

Richard Jefferson: LeBron James was sick during Cavaliers-Celtics Game 3

LeBron James was inexplicably bad in the Cavaliers’ Game 3 loss to the Celtics on Sunday.

Except maybe it was explicable.

I know he won’t talk about it, so I’ll give my big guy a shout. Deron Williams missed shootaround this morning, because he had like a little bug, just really lethargic, had no energy. And I think that’s what Bron had. And sometimes these little bugs can go around.

When Deron didn’t show up to shootaround, it kind of started clicking in his head. Because for him it was more of like, “I don’t know why I was so lethargic, why I had no energy, I had nothing.” And so, these little things happen. There was no panic.

Look, he was lethargic. They hit a bunch of tough shots. If Marcus Smart doesn’t go 7-for-10 from 3, then we’re not even talking about it.

I don’t know whether LeBron was truly sick or Jefferson is just trying to help a teammate’s reputation. It can be both.

LeBron was better in Game 4, but not quite right.

If he’s dealing with a minor illness, that could clear up by Game 5 tomorrow. It should especially clear up by the Finals, which begin June 1. That’d be great news for the Cavs, who have no chance against the Warriors if LeBron isn’t at full strength.

The uncertainty of why LeBron hit a slump now of all times loomed over Cleveland’s playoff future. But Jefferson provided reason for the Cavaliers to breathe easy.
