That part is understood and is not a problem. The question is what McGwire may have ALSO taken that he DIDN'T acknowledge. There ae plenty of yellow flags, if not red ones.
And like I say, I followed McGwire's St. Louis years very closely, and I cheered for him at the time. I WANT to believe, but even I have my doubts.
If there were no doubts about what he took, then I would say McGwire is absolutely a first-ballot HOFer. Definitely one of the top ten 1b of all-time, based on his numbers (along with Gehrig, Foxx, Greenberg, Sisler, McCovey, Murray).
Ernie Banks ended up playing a little more 1b than SS, but he made his mark at short, so I'll consider him among the top SS.
Likewise, Rod Carew and Jackie Robinson played a lot of 1b but rate higher at 2b, a position requiring less offense.
I think one of the problems Ron Santo has is that he was in the shadow of Billy Williams and Ernie Banks, and to a lesser extent, Fergie Jenkins. Dave Parker was in Stargell's shadow, Dawson was in Gary Carter's shadow, then Ryne Sandberg's. As for Murphy, I would have thought that he owned Atlanta, and would have been an early inductee. I guess I'm missing something there.
