The NBA is hard. Chances are that you, the reader, aren't good enough to play in the league. Don't feel bad—neither am I. The extreme difficulty and selectivity of the NBA makes even getting looked at an achievement in itself.

Getting drafted and actually making it in the league are two different things, though. Practically every NBA player experiences the former, but it's the latter that poses the real challenge.
