You can be unlucky. I have been unlucky. I have injured my foot and haven't played for a year and a half. It isn't the bad luck that is the issue though. For such a big man once the injuries start it is hard for them to stop. Think of Yao Ming, Ralph Sampsom, Georgie Murison (sp?), Greg Oden etc, those big guys once they start getting hurt it tends to continue. I just think if I had a big man who is still seen to have a ton of potential, who is a really skillful and even dominating player when in the right physical and mentl state, and who has great trade value, I would see if I could trade him for someone who is less fragile in every way.
