NBA to install high-tech data cameras in all 29 arenas

12 Comments

Last season 15 NBA teams had partnered with STATS LLC to put special motion-tracking cameras that record every move a player makes several times a second. It’s a flood of information but it can be useful — the information can tell you how well a player shoots after two dribbles vs. a catch-and-shoot, then it can overlay that with a shot chart to show if the player is strong on the right or left side of the court. It can measure a player’s speed, leaping ability, where a rebound from a missed elbow jumper tends to go, pretty much anything and everything.

And now that system is  going to be in every NBA arena.

The league itself is stepping up to foot the bill, reports Zach Lowe at Grantland.

The NBA and an outside tech consultant have reached an agreement to install fancy data-tracking cameras in all 29 league arenas before the start of next season, according to several sources familiar with the matter…

The cameras cost about $100,000 per year, and the expense is one reason 15 teams hadn’t yet subscribed. Some of those teams were waiting in hopes the NBA would foot the bill, and the league has apparently decided to do so sooner than many of those teams expected. Installing the cameras in all 30 arenas will expand the data to include every game played, providing teams with a more complete and reliable data set. It also raises the possibility of the league using statistical nuggets from the cameras during television broadcasts. A few teams have used in-game data at halftime to show players specific examples of things like rebounds they didn’t contest aggressively, or evidence they weren’t running as hard as usual.

This information is great — I am a proponent of teams, GMs and coaches gathering as much data as possible from every source (cameras, advanced stats, traditional scouts, their own eyes) to help them make better decisions.

The challenge is twofold: 1) How to find useful information in the flood of data? 2) How to pass that information along to players in a digestible form?

Just like “big data” in business or the flood of stats in baseball (and increasingly football, soccer and other sports) NBA teams need to figure out how to mine this information for things they can use to both teach players and win games. Toronto has taken an interesting approach to this, but we are early in the “what do we do with this info?” phase. Some teams are far more adept at this than others.

The bigger challenge is making it work for players. While a handful of players such as Shane Battier can digest a lot of information and transform it into useful knowledge, most players do not. First, you don’t want a player thinking too much on the court, you need to get them information in a time and way that they can incorporate it and make it more natural. Second, a lot of players (like most people in the general population) are visual learners — it’s far more effective to show them video clips of what they did right or wrong, or what you want them to do, than it is to just tell them. You need to make it second nature so that if a player sees an elbow jumper being taken he moves instinctively to where the rebound is most likely to go.

It’s a process, but pretty soon teams are going to have a lot of data at their disposal.

Teamwork: Spurs take ball length of court without one dribble, get and-1 (VIDEO)

This is about the most Spurs thing ever.

As San Antonio was trying to seal away its win over Memphis Thursday night, Kawhi Leonard made a steal on a lazy pass and from there it started — five passes push the ball up the court in a textbook fast break that ends with an and-1 bucket.

San Antonio got the win 97-90 behind 23 points and eight rebounds from LaMarcus Aldridge.

Watch Harrison Barnes nab a game-saving steal to put Mavericks past Clippers, 97-95

DALLAS (AP) Harrison Barnes thrived in a new position on Thursday night, and so did the Mavericks.

Barnes made the go-ahead basket, then stole the ball from Blake Griffin with 3.9 seconds left as Dallas beat the Los Angeles Clippers 97-95.

Mavericks coach Rick Carlisle started a big lineup, with Barnes moving from power forward to small forward.

“I have a little bit more energy from not banging with as many bigs,” Barnes said.

Barnes made a 14-foot jumper with 1:06 remaining for the game’s 11th lead change, making it 96-95. After he stripped Griffin, Wesley Matthews made a free throw with 0.9 seconds to play before J.J. Redick missed a 3-point attempt that would have won it at the buzzer. His shot bounced off the far side of the rim.

“We had a great shot on the last play,” Clippers coach Doc Rivers said. “That was great execution, and it was a 3, would have been a game-winner. Make, miss, we will live with that.”

Griffin scored 21 points, including nine in a row in the fourth quarter, but he missed his last three shots and turned the ball over four times in the game.

“I got to take care of the ball on the last play of the game,” Griffin said, “if you trust me with the last play of the game.”

Dallas expected Griffin to have the ball.

“I have to give credit to our coaching staff,” Barnes said. “They scouted that play well before the game. We knew it was coming to Blake. I just tried to play good defense, and I was in the right spot and the right time.”

The Clippers had their three-game winning streak snapped. Dallas, battling from behind for a playoff berth, had lost four of six.

“I don’t care about the race,” Rivers said. “I care about how we play.”

Seth Curry led Dallas with 23 points. Barnes finished with 21 and Dirk Nowitzki had 14.

The new lineup had Nerlens Noel starting at center and point guard Yogi Ferrell on the bench.

Curry started at point guard and had four assists.

“We’re going to give this a look,” Carlisle said. “It may be the rest of the year, it may not.”

Noel finished with 12 rebounds, two blocked shots and two steals, including one in the final minute.

DeAndre Jordan had 14 points and 18 rebounds for the Clippers. Chris Paul scored 15 points and Austin Rivers had 13.

The Mavericks led by as many as 12 points in the second quarter. But after trailing 44-32, Los Angeles finished the first half on a 22-4 run for a 54-48 halftime lead.

Paul had 13 points in the first half, and Jordan already had a double-double with 10 points and 12 rebounds. Nowitzki and Curry each had 10 points for the Mavericks.

Dallas started the third quarter with a 13-2 run to regain the lead at 61-56. The Mavericks took a 79-77 lead into the fourth quarter.

TIP-INS

Clippers: Redick’s four-point play in the second quarter was the 31st of his career. … The Clippers outrebounded Dallas 25-15 in the first half, but only 20-19 in the second.

Mavericks: Barnes has scored 20-plus points 35 times this season. He totaled 19 games of 20-plus in his first four NBA seasons with Golden State. … Dallas scored 21 points off 17 turnovers, nine in the second half. The Mavericks committed only nine turnovers for eight points.

THE LINEUP

Carlisle seemed pleased with the lineup change.

“We got to look at Curry at point with a really conventional team out there. We got a look at Noel with Dirk and Barnes. We got to see how things would shake out with Barnes at 3.”

THE MIGHTY FALL

Dallas’ J.J. Barea – listed at 6 feet, 185 pounds – was ejected with 5:29 to play in the third quarter after pushing the 6-10, 251-pound Griffin to the floor.

Crew chief Bill Spooner explained the call.

“The contact, in our judgment, was deemed unnecessary and excessive. The contact was to the shoulders and above to the throat. That is deemed as a flagrant penalty two.”

Marquese Chriss gets up for huge alley-oop off no-look pass vs. Nets (VIDEO)

Phoenix Suns rookie Marquese Chriss is an athletic big man. During Thursday night’s matchup against the Brooklyn Nets, Chriss got loose behind the defense for an alley-oop off a no-look pass from Tyler Ulis.

The play came about halfway through the first quarter. Ulis was out in transition, and four Nets players committed to the arc with nobody back to guard the rim.

That allowed Chriss to slip past everyone down the left side of the floor for the monster dunk.

Brooklyn beat Phoenix, 126-98. The win was the Nets’ first consecutive win of the season.

Watch DeMar DeRozan score 40 as Raptors beat Heat, 101-84 (VIDEO)

MIAMI (AP) DeMar DeRozan scored 40 points, marking the first time he’s had that many in consecutive games, and the Toronto Raptors pulled off their 19th double-digit comeback of the season to beat the Miami Heat 101-84 on Thursday night.

DeRozan shot 14 for 25 from the field and 12 for 13 from the line. He needed 38 shots to score 42 against Chicago on Tuesday.

Norman Powell scored 14 and Delon Wright added 13 for Toronto, which never led until midway through the third quarter. The Raptors allowed 33 points in the first quarter, then held Miami to 35 points over the next 27 minutes.

Playing with 13 stitches in his right hand, Hassan Whiteside scored 16 points and grabbed 14 rebounds for Miami. Rodney McGruder and Goran Dragic each had 13 points for the Heat, with Dragic shooting just 5 for 18.

He wasn’t the only Miami player to struggle. The Heat shot only 39 percent, 26 percent from 3-point range. The 84 points tied for Miami’s second-lowest total of the season, and was the first time the Heat failed to reach 90 at home.

The Raptors trailed by 15 points early and eventually led by as many as 17 – a 32-point turnaround. No one in the NBA has been better at pulling off big comebacks than the Raptors, who have come from behind six times since the All-Star break alone.

“It talks about toughness, heart,” Raptors coach Dwane Casey said. “Our give-a-crap level is pretty high, and it’s one of those things where when you count us out, we find a way. My thing is just find five men who are going to play hard.”

Neither team moved in the Eastern Conference playoff standings. Toronto (43-29) remained in the No. 4 spot, pulling within a half-game of No. 3 Washington. Miami (35-37) stayed No. 8, now just a game ahead of No. 9 Chicago and No. 10 Detroit.

TIP-INS

Raptors: DeRozan has two 20-plus-point halves against Miami this season. He had 22 in the second half on Nov. 4, and 24 in the first half of this one. … P.J. Tucker started for Serge Ibaka, who served his one-game suspension for fighting Chicago’s Robin Lopez on Tuesday. … Toronto outrebounded Miami 51-36.

Heat: Wayne Ellington played, one day after the birth of his son. Wayne Ellington III arrived Monday afternoon. … Miami’s three second-quarter field goals were a season-low for any quarter. The previous low was four, done four times. … McGruder reached double figures for only the second time in his last 14 games.

DEROZAN HISTORY

DeRozan became the second player in Toronto history to have a season where he scored 32 or more points at least 20 times. He was an 11-year-old when it last happened – Vince Carter had 28 of those games in 2000-01.

WAITERS UPDATE

Heat guard Dion Waiters missed his third game with a sprained left ankle, and remains in a walking boot. There’s still no timetable for his return, but the Heat said the swelling in his ankle continues to decrease.
