I think he turns it around. He needs to ball out on D and rebounding and post up smaller guards. His confidence is for poop right now.
He's a good utility player, but he's trying to do too much. Against UMass his perimeter defense suffered when he started focusing on getting steals - going for the homerun play and giving up a bunch of points to players who were hot from outside.
[EDIT: Nope. Rewatched the game, and none of their made threes were because McConnell gambled on steals.]
He takes care of the ball, he gets rebounds, he scraps... but his offense is pretty bad, and has been for a while before this season. He needs to stop trying to do everything, and focus on hitting 5 footers and layups. Maybe seeing the ball go through the hoop can get some confidence back, and he can be consistent out to 10-15 feet again.
Not expecting a ton from him this year.
