Not sure I'm following you here...
He isn't an elite shooter, the stats you provide bear that out. His percentages were better inside the 3 point line than out, though. Neither were elite... But he is sneaky good off the dribble, mid range, etc...
He did average double figures in the B10 as a frosh. He also averaged 2.4 assists a game, had a 2:1 assist/TO ratio, was 80% from the line...
He's a good overall player. He isn't nearly as good an outside shooter as Purdue fans claim he is. And he's horrid defensively.
He's better than Creel, overall, I'm sure. But its not a stretch to think Creel could be a better spot up shooter, and a better defender. Won't matter, like you said, he won't play. But if he's a solid outside shooter, and is any sort of adequate defender, at 6'5, he could help in practices.
My Troll had its intended effect though...
