During McGwire's interview with Bob Costas last night, he said the steriods helped him recover from injuries but didn't have anything to do with his performance because they didn't affect hand-eye coordination. Really? Then why are they called PERFORMANCE ENHANCING drugs? If McGwire believes his stats weren't padded, why did he call Roger Maris' widow yesterday to apologize? And was he crying during the interview because he thought he should have allowed his body to heal on its own? I doubt it.
If PED's increased his strength by just 10%, that turns a 350-foot flyball out into a 385-foot home run. Yes, Mark, it enhanced your performance and probably by more than 10%.
But, to me, the most maddening comment he made was the one where he played the victim. He actually said, "I wish I didn't play during the 'steriods era.'" Mark -- you're the reason it's called the steroids era! 
I think his admission is just as dishonest as his injections.
