I wondered if that was the case with guys like Mantle. Sometimes I wonder if more muscle mass = more injuries.
There are plenty of skinny guys in the HoF.
Yet we never hear want some of these guys like Brett, Gwynn, Henderson, and so many others did in the off season. They fear could be it denies much science in modern sports. We live in an age where more athletes are more brittle.
It is a mystery and no credible answers. It's not even worth trying to explain so don't bother.
