A lot of the injuries seem to be stuff he only missed a few games for. Some guys can play through them, some have the sense to get it taken care of so it doesn't linger.
Reyes injury was clearly a fluke this time. If he had strained his hamstring or something, then it might be more valid to say that the injuries are correlated (imo). Regardless I'd happily take an elite guy who plays all out and misses 20 or 30 games a year as opposed to someone who never gives full effort and stays healthy.
