People who keep saying Wally's ceiling is so high are in for serious disappointment. Maybe if he transfers and gets into a different system, he could get better. He just doesn't have the right mentality to ever be good in Frank Martin's system.
JHR, on the other hand, needs to get stronger, not use his hands as much on defense, and develop some post moves that don't involve charging the defender. All of these problems can be addressed with playing time and work in the offseason. I would be surprised if JHR isn't head and shoulders better than Wally next year.
