This is all just speculation from my end, but consider this a form of prognostication. The only factors I'm using are my own suspicion and sharp increases/decreases in statistical production, either before or after 2003. Here's who I think could be on the list of 104 players that is sealed by the state of California, the same list that revealed Alex Rodriguez tested positive for steroids in 2003.
Anyone I'm forgetting? Add them in the comments section.
