has anyone stopped to think that with the advances in training and nutrition that joe frazier today may be able to carry 10-15 pounds of muscle that he didnt back in the 70's. call me crazy.

Frazier's book Box Like The Pros gets his ideas on how people should train. He's not very much in favor of weightlifting, believing that pushups are a better alternative. I think he says something about bench press being the only practical form of weightlifting which makes it odd that he did so badly with the bench.
Whatever the case, he was very strong and had the force of a bull.
