He'll never be as good as Tony Allen, or Evan Turner in my opinion. Very average injury prone player!!
The injuries concern me a lot, too.
This newest ankle injury hopefully isn't as severe as the one he suffered his rookie year that hobbled him for basically the whole season.
The guy is a warrior, but it's perhaps this quality. which is his greatest strength, that could also be his greatest weakness, making him far more susceptible to injury.
I like the guy a lot, but I'd trade him for Okafor in a heartbeat.
