Excepting the fact that currently they are an Illegal (in most cases) substance, why? Science is science. Weather its puting 50 lbs. on Barry Bonds, or Making Nascar vehicles 2 seconds faster per lap, the choice to excel is in the hands of the individual athlete.
For instance. Suppose then, steroids are banned by the league. Then A really cagey player decides toward the end of the season, when he is run down and tired to have his body chemistry checked, and is found to be testosterone deficient. The only cure for that, is, testosterone injections. (or simpler) If the Athlete had Aids same treatment....Would his Job be denied, because of the prescribed medical treatment?
I really don't think it should matter.Not morally, not for the (ha ha ) "purity" of the Sport, as long as the league is willing to allow radically altered ball fields, and manipulate the height of the pitchers mound for a desired outcome, an athlete should be able to, should he so desire, push himself BEYOND his genetic limitations, if that is indeed his desire...(I am not advocating full blown WWF style obvious Abuse....I mean look at HHH, the guy is 275, and shredded to the bone, ALL THE TIME....that is just not humanly possible....)....I am talking about Baseball as it currently exists....Frown on it perhaps, keep it under control, but really, why should it matter?
