Starting last season, the Los Angeles Lakers began testing out a new way to better track the health and performance of their players. To do so, they culled data from multiple devices and methods and fed it into a formula that charted the players in green, yellow or red zones. As you'd expect, green is good, yellow is caution and red is bad.
More information about how the Lakers gather information is available in our story that details the Lakers' efforts toward injury prevention, but one of the key elements is SportVU -- six military-grade cameras that capture the movements of the basketball, all 10 players on the court and the three referees 25 frames per second throughout a game.
