The fallout from Monday’s admission by Mark McGwire that he used steroids for a 10-year period, including the 1998 season when he hit a then-record 70 home runs for the St. Louis Cardinals, continues.

Jeff Gordon of stltoday.com writes that “why” McGwire juiced is the biggest question.

We didn’t expect Mark to rat out teammates like Canseco or go into gory detail about needles and buttocks and such. But we did expect some real insight into why he went veered onto the steroid/HGH/andro path.

Bob Wojnowsk of the Detroit News says the admission doesn’t change a tarnished legacy.

McGwire isn’t a confirmed liar, only a confirmed cheater and a confirmed opportunist. And to be honest, I don’t care if he truly is remorseful. … It doesn’t matter anymore, and it doesn’t change anything. I doubt any of the steroids guys are getting into the Hall of Fame.

Bill Madden of the New York Daily News writes that it’s too late for McGwire to earn induction into Cooperstown.

I do believe McGwire’s primary motivation for coming clean now was his desire to get back on the major league field with the Cardinals and teach hitting — which couldn’t happen until he addressed the issue — and not necessarily an attempt to improve his image with the Hall of Fame voters. He has to know that finally talking about the past can never eradicate the past. Rather, it has served to further illuminate it and remind everyone, the players and their union, the media and, yes, the commissioner of baseball, that we were all complicit in looking the other way as all these cheats tarnished the game forever.

Pens Ken Rosenthal of FOX Sports: Sorry, Mark McGwire is still living a lie, so the truth cannot set him free. … in an interview with Bob Costas on MLB Network, McGwire came off nearly as badly as he did in his infamous appearance before Congress in March 2005.
