Wow. Tyler Cowen:
In other words, this “technology” has been legal since 1979, yet only recently has it started to come into its own. (Some teams still haven’t figured out how to use it properly.) And what a simple technology it is: it involves only placing your feet on a different spot on the floor and then moving your arms and legs in a coordinated (one hopes) motion. The incentives of money, fame, and sex to get this right have been high from the beginning, and there are plenty of different players and teams in the NBA, not to mention college or even high school ball, to figure it out. There is plenty of objective data in basketball, most of all when it comes to scoring.
