First off, anything you get from a second round pick is a bonus.
Secondly, I don't think looking at statistics is the best way to gauge all players. As Western Kentucky fans have pointed out here before, basketball was one of two sports Jeremy played in college (track being the other), and so he didn't have the option of putting on weight or devoting all his time to basketball. Also, Western Kentucky needed him to play at the 5, even though he seems more like a 3/4 (offensively, the played outside-in, which also didn't help his numbers).
What we do know is the guy is an elite athlete. Whether he figures out the other stuff (is he a hard worker? Can he gain weight? Does he have or can he develop BBall IQ and skills?, etc.), we don't know yet.
