Tyler can improve in each of these areas and he probably will. My point is that I just don't think he's ready for the pros right now. The good thing for him is that this is just my opinion, which amounts to nothing in his world. He'll make the choice that he believes in.
I think he could definitely benefit from another year. I completely agree with that but Booker could've also. Worked out well for him. Nobody thought he was going to leave after a single season. We know the NBA drafts on potential and the modern NBA loves players like Tyler. So, Id be really shocked if he were to come back.
