Being a basketball guy, it amazes me the amount of statistical categories the NBA produces for teams and players. Of course they provide analysis for points per game, rebounds per game and such. Now, more in-depth analysis includes points per 48 minutes, efficiency (which is a crazy formula), true shooting percentage, and points allowed per 100 possessions. My guess is that since the teams themselves breakdown all of this data, the NBA wants to solidify the link between the league and its fans. Honestly, the fans have no real reason to use these stats, but I guess its keeps them engaged with the game and makes them feel important.
