Just as skilled at this stage as Grant was last year, and definitely bigger.
I agree with your comments but the NBA is going to question whether he can make the transition to forward and be successful at that position in the league. He probably needs to improve his shooting range and ball handling skills to make it in the NBA.
There is also a huge age difference between these players. Christmas is 23 years old while Jerami was only 19 last season. The NBA could look at how much Grant's game improved last year and envision him making a lot more development over the next few years. It is harder to have those expectations about one of the oldest players in college.
