I've been saying since January that he needs to go pro.
1. He has arthritis.
2. He will not get as much playing time next season, and will definitely not be a top three option.
3. The draft, hypothetically, should be stronger after next season.
4. He is not going to grow three inches, which is his biggest hindrance.
He hit 44.6 percent of his uncontested jump shots this season. His shot release is not getting any quicker, his defensive awareness is not going to get any better and he will not be asked to take the ball off of the dribble any if he stays. Staying a year does nothing other than adding a year of wear and tear on his joints. He will go late second to undrafted, either way.
