TR,
I've gained a whole 20 lbs over my playing weight in college, 30 over my fighting weight in the service. I can buy the weight gain if it came over an extended period.
I don't think anyone has a problem with your not being willing to "convict" Bonds or others on the evidence that is out there. Unfortunately, you seem to be taking it to an extreme and denying even the possibility that Bonds and others have used steroids. That may not be how you think, but that is how you come across.
Martina has managed to look very similar other than the obvious signs of age. She still looks like she is taking testosterone supplements. Compare Chrissie in her prime and Martina in her prime and tell me that there's no way that Martina took steroids.
Remember, I played competitive tennis.
I will say that as far as the Angels go I will categorically state that Scott Shields and Ramon Ortiz do not take steroids.
You know Barkely can say that as often as he wants but he was still a role model for a lot of kids. Being a role model is a result of being a professional athlete and not something that can be shrugged off.
