This time it is from the NBA:
The league on Thursday announced plans to install sophisticated tracking cameras, known as the SportVu system, in every arena for the coming season, creating an unprecedented treasure trove of data about virtually every wrinkle of the game. SportVu, developed by Stats LLC, records data points for all 10 players, the three referees and the ball, every 30th of a second, measuring speed, distance, player separation and ball possession. Every step, every dribble, every pass, every shot, every rebound — really, every movement — will be recorded, coded and categorized. … The N.B.A. is the first major professional sports league in the United States to fully adopt the SportVu system. It will have other implications for the league, far beyond the playbook and the box score. Not everyone might welcome the change. General managers will surely exploit the more sophisticated statistics when negotiating contracts with player agents. Not all assists, points and rebounds are created equal — and teams will soon be able to demonstrate that vividly. Referees are also tracked by SportVu, which means the league will have yet another tool to analyze every call, non-call and missed call as it ranks its officials. Those rankings help determine which referees are chosen for playoff assignments and the finals.
There is yet further information here. One prediction is simply that players will pass the ball more, even when it does not result in an assist. Team defense will improve too. Furthermore some injuries may be partially forecastable and thus preventable. If applied at the college level, the efficiency of the draft will improve and this will help restore competitive parity. Truly injured or otherwise disadvantaged players may lose some insurance value, since it may be clear earlier on they are not going to recover or improve.
