He said he was burnt out in February his first couple seasons because he was always trying to dunk on everybody and be physical and over power his opponents. So, after seeing game 7, it looks to me like he needs to learn when to turn it on and off.
For a man his size who can jump like he can, he should be working on becoming a better paint defender. He really messed up on defense during a fast break as he was the last man back, stepped in front, then stepped back to guard the perimeter player as Jason Terry went straight to the basket.
