I have though of that and WHILE I AGREE it EXITS and that it is the reason for INCREASED HR output that DOES NOT explain BB hitting 74 in ONE year and NEVER even 50 any other. The dilution of pitching has been existent for years. Also see my previous post concerning INJURIES preventing something from happening.
I really don't KNOW if BB or MM were/are on steroids or if all MLB players are, I believe it to be a factor but NOT one that will answer my question.
