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.

Purdue’s Caleb Swanigan staying in 2017 NBA draft

Purdue’s Caleb Swanigan declared for the 2016 NBA draft, struggled at the combine, withdrew, got into great shape, had an All-American sophomore season, declared for the 2017 draft.

This time, he’s not turning back.

Swanigan:

Swanigan is a borderline first-round pick. He has a couple NBA-ready skills the good teams that typically pick late in the first round might covet, but thanks to trades, teams that didn’t win a playoff game this year hold most late first-round picks. They might pick someone with more upside than Swanigan.

Swanigan is a tenacious rebounder, particularly defensively. He has excellent fundamentals, size (6-foot-9 with a 7-foot-3 wingspan) and ability to read the ball, and he crashes through contact to hunt boards.

He’s also a quality post-up player who can finish with either hand and has the passing ability to make that play work.

But Swanigan is slow. NBA teams have become increasingly adept at running plodders like him off the court by dragging them into pick-and-rolls. Even when on the court, he hasn’t protected the rim at satisfactory levels.

Swanigan has overcome his athletic limitations as a rebounder. He hasn’t done so in other facets of defense.

He’s hardly a dinosaur offensively. He made 45% of his 3-pointers last season, and though I’m not confident that will translate to NBA 3-point range (give the small sample and his form), he should be at least a midrange threat.

Swanigan is also just 20, young for a sophomore. He can improve.

But it’s just hard to look past his defensive limitations.

Hawks hire Travis Schlenk as general manager

The Hawks picked Warriors assistant general manager Travis Schlenk as their next general manager. All that was left was negotiating terms.

That’s done.

Hawks:

The Atlanta Hawks today announced the hiring of Travis Schlenk as General Manager and Head of Basketball Operations. He will start leading Hawks basketball operations on June 1.

Schlenk worked his way up the latter and helped the Warriors become the envy of every other NBA team. He deserves this opportunity.

But the job won’t be easy.

The Hawks are stuck between two directions. On one side, they have veterans Paul Millsap (a 32-year-old pending unrestricted free agent whom the owner has basically promised a huge contract) and Dwight Howard (who sounds unhappy). On the other side, they have a youth movement featuring Dennis Schroder and Taurean Prince. Tim Hardaway Jr., who bridges the age groups, is about to enter a potentially tricky restricted free agency.

Keeping the core together offers the upside of a playoff-series victory or two annually, modest outcomes for the cost. But a fragile Atlanta fan base might not tolerate a rebuild.

Schlenk works for owner Tony Ressler, and Ressler sounds committed to maintaining the status quo by keeping Millsap. It’s now Schlenk’s job to execute that vision or convince his boss to approve a different direction.

Potential none-and-done first-rounder Hamidou Diallo returning to Kentucky

The more I’ve looked into the 2017 NBA draft, the less impressed I’ve become. There are a few bright spots in the first round relative to an average draft – No. 2, 5ish-10ish, 17ish-22ish – but I’m not convinced this is the generationally strong draft it has been touted as.

In the absence of prospects who offer secure promise, why not turn to upside? Hamidou Diallo offered plenty and was increasingly viewed as a first-rounder.

Yet, he’ll return to Kentucky for his freshman season.

Diallo:

A highly ranked recruit, Diallo began last school year at a prep school then enrolled at Kentucky for the spring semester. He practiced with the Wildcats, but never played.

Then, he went to the combine and posted excellent measurables: 6-foot-5, 6-foot-11 wingspan, 44.5-inch vertical and strong agility and sprint scores. Just 18, Diallo might have been the second-youngest player drafted this year (behind only Ike Anigbogu).

It wouldn’t have taken long – likely somewhere in the middle of the first round – for a team to bite on all that potential.

Instead, Diallo returns to Kentucky and must now show his ability to actually produce in basketball games. If he does, there’s no limit on how high he goes in the 2018 NBA draft. If he doesn’t, he’ll regret missing the opportunity to get drafted before his game got picked apart.

Report: Bulls expect Dwyane Wade to opt in

Dwyane Wade said he wants to see the Bulls’ plan for Jimmy Butler and the rest of the roster before deciding on a $23.8 million player option for next season.

K.C. Johnson of the Chicago Tribune:

I can tell you is most everyone associated with the Bulls believes Wade will pick up the option and remain in Chicago for a second season. More surprising things have happened in league history, though. So stay tuned.

This could be a tell that Wade will opt in. The Bulls could obviously be positioned to base their prediction on inside information into Wade’s thinking.

This could a tell the Bulls won’t trade Butler. If they know they’ll keep Butler, they can extrapolate what that’d mean for Wade.

Or the Bulls, like so many of us, just assume a 35-year-old Wade won’t turn down so much guaranteed money at this stage of his career.
