I always thought he reminded me a little of Bo Outlaw, or maybe Tyrone Hill. I think they both may have been better defenders...but I really remember both of them later in their career, so I can see Powe continuing to improve to be a similar defender.
I really think he is going to make his career in the same way they did, by being a tough rebounder, and energy guy, and a guy who does most his damage offensively on garbage baskets, like putbacks, dishes from driving guards, and of course by drawing contact and getting to the line.
I know some people on here are convinced that he is going to be more of a low post presence offensively...but I just don't see it. His strength is in playing off others, and using his aggressiveness to finish, or draw contact inside. He can take advantage of single coverage, if teams are not paying a lot of attention to him, but I never see him being the type of big man who can continue to be fed in the post and score past double and triple teams.
