I can't figure out what Winston is trying to say. Historically, some of the biggest names (at least on the defensive side) have admitted to using steroids. Recently, Shawne Merriman was suspended for use of PED. 52 Pro Bowlers have been accused of using PEDs.
I think it is almost expected in football. That does not make it right, but football is about strength, size, power and speed. Baseball is, at its core, a game built on eye-hand coordination and reaction. Being fast and powerful can't help you if you cannot hit a baseball, pitch or catch.
And, training regimens for baseball is now year round, with lifting and other strength-enhancing programs in place (as with basketball).
For the record. McGwire admitted to cheating - he did something that impacted the game being played. The ball he hit went further, and he hit the ball harder because of the PEDs. As it stands, Rose is accused of breaking a rule (betting on baseball), but not cheating in a game. (To date, I don't think anyone has found evidence that he managed games based upon the way he bet - that may be out there, but I don't think he is accused of that per se). There is a difference in my mind. For me, Rose belongs in the Hall of Fame because of his career as a player - his stats were not impacted his violation of a rule - McGwire's were.
PEDs and Football.
