Your vision is stuck in today's sight. What did you expect from a guy that has been **** all over by his coach by sending to DL in a team full of mostly not so greater players compared to his level? He is a damn rookie and I saw what I needed from him earlier this season. If I were the Jazz FO man (since the HC won't do jack**** about it) I would give this guy to a physician and bulk him up, make him work with a bigman coach that is also big. Not like Ty who falls down when Kanter hits him. I think there is a gem in there. And it's worth working on.
Not so sure about Rudy bulking up. Getting stronger yes, but one of his greatest assets is his quickness, especially for a guy his size. Bulking up would take that away. Not every successful player is built like a brick-doo-doo house. Durant and Ray allan and Reggie come to mind.
