Yet it's when he gets to the free throw line that Simpson's problems begin. He shoots his foul shots so flat that they barely get above rim height, and that poor technique extends to his jumpshot, which basically does not exist. Since he's not a threat to post up or do much off the dribble, this is a problem. Defensively, Simpson's "activity" (I hate that cliché, but it's apt here) has its uses, as he's able to cause turnovers and win the ball with his rebounding and disruption of the passing lanes. (He can also get up for some blocks from time time, although he probably helps too much.) Yet his physical disadvantages hinder him on this end, too, where he can be both overmatched in the post and beaten off the dribble on the perimeter. His energy can only mask so much.
If he was a better shooter, or just a bit bigger, Simpson would have been drafted. As it is, he'll now have to ply his trade the hard way.
