Why are Jersey Numbers Above 50 so Rare in Basketball?
In basketball, the most common numbers are in the 40's and below, by an unbelievably enormous margin. I know that one of the reasons is that most teams rarely have more than 15 players, which is the maximum number of players a NBA team is allowed to have. But especially in today's time, where people "dare to be different" and where some fans would love to see a player cut his own path and not follow in someone else's shadow, a player still almost never chooses a number higher than 50.
The 2 most recent cases in the NBA that I can recall are Drew Gooden (#90 for the Spurs) and Ron Artest (#96 for the Rockets, a.k.a. the Queensbridge jersey) a couple of seasons ago. Just about everyone else in the league had a number that was below 50.
Aside from a small roster size, why are these higher jersey numbers so rarely chosen?
