I agree with everything you said. We have an abundance of solid wings. JC absolutely has the body for a 4 or 5. He also has the talent level to play there. After all, he jumps center for us. What he lacks is the mindset (IMHO). Perhaps it is the European mindset to emulate Dirk Nowitski. If TK can school him on post moves and he wraps his mind around the act that he should be guarding the paint, tracking down rebounds, posting up and shoot the occasional 3, we may have a beast. He he continues to think of himself as a glorified guard, we are wasting talent.
I went to one game (Sacred Heart I think) where TK got into foul trouble early and JC literally took over the game inside. That is his role again only IMO.
