I have Hunter as POB's short/mid-term ceiling. It'd be an improvement at the backup 5.
So, if Miles is indeed able to play, I'd do Scal+Pruitt for Hunter. Not Powe, unless we're signing Marcus Haislip.
If Hunter could learn how to fight for the position in the post, especially on the defensive end, he'd be a much better player. If I believed that was possible, I'd trade Scal/Pruitt/Powe for him. But I don't.
