Exactly.
It's got nothing to do with talent, rather he has it or not, he simply isn't going to be able to stay healthy.
Sean Lee has proven he can play and if they decided to cut him tomorrow I wouldn't be upset about that either because it's obvious the poor guy simply isn't ever going to be able to stay healthy.
That's the unlucky part of pro sports sometimes. It doesn't matter how talented, how hard you work, what you dreamed or wanted to do...there are simply going to be guys whose bodies just aren't going to do what they want them to do.
It happens.
