One thing Chaz has going for him is his success has never really hinged on his athleticism so injuries may not affect him as much as players who heavily rely on it. Another thought is that he keeps playing at a high level when he gets back. I'd understand the "his career is done" woes if he showed signs of decline when he gets the chance to play, but he hasn't, he continues to get better. Maybe he'll end up having a career filled with injuries, but without a crystal ball I'm going to just hope that this has been bad luck, which is strengthened by the fact that his 3 surgeries have all been on different parts of the body. It's not a single recurring injury which usually is what ends careers, it's 3 very different injuries.
Or he could be Martin Havlat and tear his groin climbing over the boards for a shift.
