Where I think Grant will eventually excel is as a stretch 4 offensively. He will - eventually - have a very good outside shot. He'll be a $$ pick and roll player. I don't think he'll ever be an elite defender because he's just not tall enough to guard great big men, but I do think he can be adequate.
He's someone who's always improving. At UT, he started out as a below average FT shooter, and improved every year. He also started to develop his outside shot, but he was basically the only inside presence we had, so most of his college career was spent on the block. He's going to have to play a totally different style, but we saw glimpses of it in college and this past summer.
