http://keepingscore.blogs.time.com/2013 ... n-the-nba/Barring any last-minute glitches, hoops fans will have access, starting on Friday, to such passing stats, and a whole new set of data delivering new layers of insight into basketball. On NBA.com’s expanded statistics page, fans will be able to see and sort info from STATS LLC’s SportVU Player Tracking system. In all 29 NBA arenas — there are 30 NBA teams, but remember, the Los Angeles Clippers and Lakers share the Staples Center — six cameras are installed in catwalks, tracking the movement of every player. A software program ingests all the data and spits out statistics like assist opportunities, the distance each player travels during a game (on Tuesday’s opening night, Blake Griffin ran 2.71 miles, tops among the six teams that played), and a player’s defensive impact (the Orlando Magic made just three of nine shots against Indiana’s 7’2″ center Roy Hibbert while Hibbert was defending the rim).
Rebounds also get a makeover. The total number of rebounds a player compiles often depends on factors outside his control. If the opposing team is shooting badly, for example, you can snatch more bricks off the boards. What’s more relevant: if a player is near the ball, at what rate does he go and grab it? “Rebound Chances” measures the number of times a player is within 3.5 feet of a rebound during a game: from there, SportVU calculates a player’s “rebound percentage,” based on the number of boards he actually grabs.
TIME got a sneak peak at the NBA’s Player Tracking site; it’s informative and easy to navigate. Other subcaterogies include a player’s performance when he drives to the basket, and how effective he is when he just catches the ball and shoots. In Miami’s first game, a 107-95 win over Chicago, Shane Battier, the king of finding himself open as Miami’s star players drive to the basket, shot four-for-four from three point range after catching, squaring, and firing away. A personal, if somewhat random, favorite: the data tells you how fast, on average, players were moving in a game. Congratulations to rookie Tony Snell and veteran Mike Dunleavy, both of the Chicago Bulls: you were the fastest players on Tuesday night, each moving an average of 4.9 miles per hour.
