I thought he was supposed to be a good shooter (and looked decent earlier in the year) but his shots looked way off last night and he missed the front end of a big 1-and-1.
To me he just appears a little careless with the ball and not used to the level of competition. Based on his bloodline we know he has the talent so I just think it's a matter of time getting use to D1 ball and gaining experience like Jeremy said.
