Then he's got the odds in his favor. It's one thing if it's the same thing over and over. It's another thing if it's something different each time. The first case is chronic injury that won't heal, the second is bad luck. If it's just bad luck, that can certainly change.
He is just a kid that has the injury bug. He's had at least 5 different injuries that I can remember. It's unrealistic to expect to be a significant contributor going forward in my view. When he finally made it through a week of practice he got hurt in warm-ups...any contribution from him is a pleasant surprise for me.
