Moore won't get any real playing time in the post unless he adds like 20-30 lbs of muscle. I don't see him getting much playing time in his first year or two so I don't think he'll affect Wilkes' position on the court. I don't see his commitment having any positive effect on Wilkes.
Yeah he is NOT a guy who is going to step in and immediately play a lot in the B1G. So I really don't see it having any effect on Wilkes at all.
