Kevin Johnson was the epitome of a role player his senior year. He was basically just a catch and shoot guy on offense (and not a very good one). He was an excellent defender though, with a high steal rate and only 2.5 fouls per 40 minutes. Cronin loved players like that, but I think we can (and need to) do better. We don't have Caupain, Clark, Evans, and Washington to score for us.
In my opinion, MAW's ceiling is Kevin Johnson with maybe a better shot and worse D. His scoring total is a little higher because he's playing a few more minutes. His shooting numbers are almost identical to Johnson's senior year. I don't see him becoming an offensive threat because he's so limited with his right hand. The only way I think he'll become more efficient is to shoot 37% from three like he did last year. If he's not more efficient, then I don't want him scoring more.
Mason is a better shooter right now, and he should improve his defense, foul rate, and turnover rate like almost all players do after their freshman year. Those things are more predictable than shooting. Ideally they are both role players, but I just don't think this team will be very good if MAW is getting 30+ minutes on the wing.
