yeah, and what happened with Gwynn was natural? no, it was a bad knee, lots of food, and genetics. I'm 26, and my body shape has changed dramatically since I was 18. I'm sure most here agree that bodies change. What's crazy is that people seem to think McGwire and Bonds were products of steroids. McGwire was the alltime homer leader at USC, and Bonds was looking like a Hall of Famer when he first signed with the Giants. His homer binge of late is also a product of him not trying as hard in the field, which has resulted in none of the injuries that plagued him in his 30s.
