I'm concerned but not necessarily due to all the spills. He's built like a linebacker and I think he can adapt. But I do think he's the type of player that gets by on lightning speed and athleticism. Once he loses a step, his production will fall off quickly.
It brings to mind Roy Jones, Jr. Lightning reflexes and one of the most dominant fighters I've ever seen. But boxing is a game of inches and split seconds, just like bball. As soon as he lost half a step it was over.
