I don't think that Nixon is horrible, he's just being asked to do too much at this level. If somehow, we had LW and THT on this team, Nixon would be a backup guard and defender. I think that he would do just fine in that role. Or even if Lewis would have upped his game, we would have a lineup of TH, Bolton, Lewis, THT, Solo...that's a bubble team at worst.
I agree with everything that's here. However, I still believe that if a guy's ceiling is backup guard and defender he's not worth burning two years of scholarship for one year of production.
