Wow, some of you guys are overrating Lavine by an insane margin. His athleticism will keep him in the league, but he's a shooting guard who can't shoot or finish through contact. He came off the bench and averaged single digits for a mediocre UCLA team. Not that he can't improve, but as of now I don''t see much to get worked up over.
As someone who watched every UK game last year, I'd say a lot of that is shot selection. The UK offense was horrid for months so the coaches sort of let him chuck it out of desperation at times. His mechanics are smooth and when he gets a good look he can knock it down. With some proper spacing and improved shot selection I wouldn't be surprised if he's around 40%.
