Remember how Isaac Bruce used to be considered the extreme of injury-prone, until he stopped getting unlucky? These guys get hit hundreds of times per year, and all it takes is one bad one and they're injured. Sure, a fair amount is attributable to certain, controllable things (running style, for starters), but I have a hard time looking at the fact that Morris has been injured each of the last 2 years and saying that he's a waste of a roster space because he can't stay on the field. There are huge guys on the other side of the field being paid millions of dollars to hit our guys as hard as they can- injuries are going to happen, and our guys don't suck just because they get hurt.
