I want to be an Exum fan, but so far in his entire career, he just hasn't been very good. Unbelievably limited on offense and very low on confidence/assertiveness for a 5th pick. His defense has regressed while his offense actually has shown only small flashes of improvement, but I wouldn't play him either. I think it's fine to let him play a little and see where he's at that particular game, mentally. It's not good for his continuity but it's not like we're looking at a wiggins or kobe talent. I still think he'll be a good player, but let's not blame Quinn for what's happening now. He stinks. Mack's not that great either, but Mack is only a slightly negative influence in the game at this point. Exum has not played enough basketball in his life to be great at it, needs to develop in practice and in solitary work outs. He'll get adequate chances to prove whether he's good or bad, and right now he's just not good.
