Pretty cool you went to school and played ball with Thome.

I am sure you were on some good teams. So then you understand it is very likely Jim was going to get alot bigger and stronger based on how tall he was, the physical size of his family, and his body structure (tall, athletic frame, and big shoulders). It doesn't always work that way but that is a factor when scouts evaluate players. Does he have the potential to get bigger. Some males can grow into their early 20's and muscles can continue to grow until your late 20's. You then can maintain your strength a few years before you start to lose strength even with training. Your body just doesn't naturally produce or grow muscles at the same rate it did when it was younger.
I am not questioning Bonds, McGwire, or any of the others caught as they are cheats and guilty. They deserve nothing, let alone the Hall of Fame. I think that players want as few people to know as possible. They want others to think they are natural and this strength gain is from hard work. Don't talk about it around players. I think that is one reason why you are hear more from informants, dealers, trainers, doctors, Balco, etc than you hear players talk. Yes some players probably talk to each other about what they take or how to take it or where to get it but those are the id!ots and jerks. I think it is very unlikely that all in the locker room know what a few on their team have done. They would know even less about other teams and their players. They may suspect but have no proof. If you call someone out with no proof you can't just give your opinion.
You are certainly entitled to your opinion. I just don't see how that makes clean players guilty. They have made the correct choices. They had the ability to play professional baseball where many others didn't. The overwhelming majority of H.S. and college players don't have this ability. Clean players have done nothing wrong. Your ex teamate Thome is not a liar or a jerk. He has character. He has earned his reputation as one of the good guys in baseball as Girardi did and so did hundreds of other clean players in any given season.
