You need only take a look at the bodies of todays players vs those of players in the past. I'm think of guys like Jimmie Foxx (his muscles had muscles) and Ted Kluszewski. People always said how buff guys like this were. But if you look at many of the average players today they are in much better shape. All six packs and such. I really feel that the amount of muscle on todays players can cause more injuries than those of the past. Some of the injuries today were unheard of in the past. Guys tearing muscle off of bone! As the above poster noted, too much muscle not enough stretching. But I think the too much muscle versus their frame outweighs any stretching they would do.
