Someone always says that in a Meyers Leonard thread, but projects are supposed to develop. After 2 years, a 2-year project is part of the rotation. 2 years doesn't mean that after 2 years, only 2 more years and he may be only 2 years away (total 6).
He has not only not improved in any way, he has regressed. Early in his rookie year he could catch the Lillard alley oop pass and always make it. He had lost that courage by late in his rookie year. Since then his main priority has been to protect his contacts from getting knocked out. When he is within 5 feet of any potential collision, he turns his back to the action and often actually bends into the natal position and covers his head with an arm.
I have never seen such a coward in the NBA. If you watch a high school team, there will be one freshman substitute every decade who acts like that. But at this level it's amazing, especially from a guy that tall. He was known in college as being too emotional and close to crying, and has a mental problem. I feel sorry for him, but I also know that he needs about 6 years to become barely passable in the NBA.
