My perspective: Stiemsma looks like he has more potential than Perkins simply because he can hit the outside shot. (though Doc had to get him to say it to himself in front of the whole team in practice that "My name is Greg Stiemsma, I'm a shooter" to get him to believe it himself) However, he's a rookie; IOW he's untrained. Time will tell if he is motivated to work, take constructive criticism, keep his confidence level up, and improve.
