Former missile tracking technology revolutionizing NBA stats

4 Comments

People who dismiss the NBA’s statistical revolution as a bunch of nerds in front of computers with Google-like algorithm don’t get the real picture.

The reality is that a stats-loving coach who incorporates them into formulating his game plans is about to win an NBA title in Miami. The reality is pretty much every team has an advanced stats guy in house.

And those stats are going to the next level now thanks to former missile tracking technology that can literally track a player’s every move on the court. Teams are already paying for the next level of advanced statistics and the early results have wowed statheads at places like the SLOAN conference at MIT.

There’s a great story on the technology at fastcodedesign.com (go read the entire thing).

Now, SportVU systems hang from the catwalks of 10 NBA arenas, tiny webcams that silently track each player as they shoot, pass, and run across the court, recording each and every move 25 times a second. SportVU can tell you not just Kevin Durant’s shooting average, but his shooting average after dribbling one vs. two times, or his shooting average with a defender three feet away vs. five feet away. SportVU can actually consider both factors at once, plus take into account who passed him the ball, how many minutes he’d been on the court, and how many miles he’d run that game already.

A perfect example of this principle is in how SportVU can track assists. Traditionally, the NBA will award a player with the assist if they pass the ball to a player who immediately scores a field goal. It’s a human calculation, a judgment call based more on feel than science (much like a foul). Aside from clear issues of accurate counts, think about everything that generalized “assists” stat misses: What if the best passer in the world is on a team of people who can’t shoot? They’re making the correct play but getting no credit because they’re surrounded by mediocrity. But put this playmaker on a good team, and that team might excel.

SportVU can track these potential assists, and even track the person who passes it to the person who makes the assist. Now scale this level of assessment to every single skill in basketball, and our view of players could change as we know it.

The next level of challenge for coaches is to turn this data into something the players can assimilate. It’s one thing to tell a player “Kobe Bryant shoots X percent less if you force him to go left for two dribbles into a pull-up jumper” and another for a player to really grasp it and apply it in a game.

Heat coach Erik Spoelstra (among others) tries to put these tips in video packages — don’t tell the player, show the player. Most of us are visual learners, if we see it we process it faster.

But the revolution is here to stay, and with companies like SportVU there is only going to be more and more data out there to mine for an edge. And teams will pay and do just about anything to get an edge.

Kevin Durant gets into Twitter debate with reporter over White House comments

3 Comments

Kevin Durant became the latest Warrior — joining Stephen Curry, Andre Iguodala, and Shaun Livingston, that we know of — to say he would not visit President Donald Trump’s White House as NBA champion. Which is all kind of moot because it’s unlikely the White House invites them and outspoken Trump critic/Warriors coach Steve Kerr and his players any way. (The White House’s biggest concern should be that Kerr accepts the invitation and uses that platform to challenge the president’s policies and style in front of him.)

Durant’s comments led to plenty of talk on sports talk radio and around the sports world online about whether a player or team should decline an invitation from the president. It’s not a new debate, Tom Brady denied that politics is why he didn’t visit Barack Obama’s White House (although I’m not sure many believed him), but KD’s on a big stage now so it became a talking point.

Former ESPN reporter Britt McHenry questioned a player not visiting the White House, and Durant responded, leading to a little Twitter back-and-forth.

Durant had previously Tweeted in response “by doing the opposite, I am inspiring more people” but that Tweet was deleted.

There is no one correct way to protest a person/policy/action, McHenry may see things differently, but Durant has chosen to stay away. That’s valid — traditionally these “champions to the White House” things are tedious photo ops with a few bad jokes thrown in. Having a hoops fan/player in Obama in the White House made the NBA visits more entertaining the past eight years, there was some trash talk, but still, they are largely just a public relations moment. If KD doesn’t want to play the PR game with Trump, that’s a legitimate response.

This has all been a tempest in a teapot. Until/unless the White House actually invites the Warriors to come, it’s all kind of moot.

Dwight Howard on Hornets’ coach Clifford: “It’s a great feeling when somebody believes in you”

Dwight Howard‘s game is much better than his reputation among fans.

He’s not the Defensive Player of the Year/All-NBA/MVP candidate level player he was back in Orlando, but Howard is still one of the best rebounders in the game, he’s strong defensively, and he’s an efficient scorer inside. He’s a quality center, if he plays within himself and is used well. His perception as a guy who does not take the game seriously and held back Houston and Atlanta in recent years has validity (he plays better in pick-and-roll than on the move, but wants the ball in the post), but the idea he is trash is flat-out wrong. He’s still good.

Howard wants to change his reputation, rewrite the final chapters of his career, and told Adrian Wojnarowski of ESPN that Steve Clifford’s Charlotte Hornets are the place that is going to happen.

“The other places I was, the coaches didn’t really know who I am,” Howard told ESPN. “I think that they had perception of me and ran with it. Cliff knows my game. He knows all the things that I can do. I’m very determined to get back to the top. It’s a great feeling when somebody believes in you. They aren’t just saying it; they believe it. It really just pushed me to the limit in workouts: running, training, everything. I want to do more.

“In Orlando, I was getting 13-15 shots a game. Last season, in Atlanta, it was six shot attempts. It looks like I’m not involved in the game. And if I miss a shot, it sticks out because I am not getting very many of them. But I think it’s all opportunity, the system. I haven’t had a system where I can be who I am since I was in Orlando.”

Howard averaged 8.3 field goal attempts per game in Atlanta, which is about five a game below his peak. Last season 75 percent of Howard’s shots came within three feet of the rim — is is not there to space the floor, however, he can still move fairly well off the roll and is a good passer for a big.

Last season, 28 percent of Howard’s possessions came on post ups, and he averaged a pedestrian 0.84 points per possession on those. On the 21 percent of shots he got on a cut, he averaged a very good 1.36 PPP. When he got the ball back as a roll man (again on the move), it was 1.18 PPP. The challenge long has been Howard is better on the move but doesn’t feel involved unless he gets post touches, and if he doesn’t feel involved and engaged he’s not the same player.

Maybe Clifford can make this all work with some older plays where Howard feels comfortable.

Charlotte, with Howard in the paint and on the boards, should get back to being a top 10 NBA defensive team, not the middle of the pack as they were last season. Clifford is better than that as a coach, and Howard is an upgrade in the paint (on both ends). Charlotte should be a playoff team again in the East.

But it all will come back to Howard. Fair or not. And Wojnarowski is right, this is Howard’s last best chance to write the ending he wants to his career.

Mavericks sign Jeff Withey to one-year contract

Jeff Withey‘s ex-fiancée accused him of domestic violence, but he was not charged.

That frees him to continue his basketball career, which he’ll do in Dallas.

Shams Charania of Yahoo Sports:

The Mavericks could use another center, even if they re-sign Nerlens Noel. Salah Mejri is the only other true center, though Dirk Nowitzki will now play the position.

Withey is a good rim protector. Just don’t ask him to do anything away from the basket.

Dallas annually brings excess players to training camp and has them compete for regular-season roster spots. Whether or not his salary is guaranteed, Withey will likely fall into that competition.
