Sounds like he's had a good opportunity and is a positive person. As long as he's not overly critical of BYU, I think BYU fans shouldn't be hard on the guy.
With that said, I'm not sure he's ever lived up to expectations based on all the hype that seems to surround him. It almost seems like the doubters may have been right...that his size is really a problem for him, which has led to significant durability issues.
