I understand it was pretty much a don't ask don't tell policy in MLB until the regulations were instated in 2002. Still, if they KNEW players were juicing and failed to act in the name of money, this could leave a serious black mark on all of Major League Baseball.
Also on a side note, I don't think pitchers take steroids. I remember reading somewhere that the risks far outweigh the reward for pitchers. It puts an enormous amount of strain on the arm I think, but maybe someone who knows more about this can fill in the details.
BTW does anyone know the link to that blog site that had pictures of Bonds, Sosa, and Giambi's heads and analyzed them for possible steroid use?
