Here is my thing, did Bonds use Steriods, probally, did a whole lot of other players, just as likely as bonds, did a lot of pitchers, most likely, they had the most to gain. The thing is baseball knew and ignored it, they made the bed now they must sleep in it.
So if they all players (or even most) did steriods then it was a level playing field. The things is if you wanted to argue fairness. Ruth had an advantage of it being only white players. Arron had a advantage of playing in Atlanta (AKA the Launching pad), Bonds may have had an advantage with steroids, but also did this is probally the hardest park to hit a home run currently , and one of the hardest parks ever.
