It’s only been two weeks since Mark McGwire’s teary-eyed interview with Bob Costas, but the slugger’s steroid use already feels like old news. If 70 dingers didn’t hint that Big Mac was taking more than just his Flintstone vitamins, all you had to do was take a look at the increase in his hat size — the man’s head blew up like a sorority sister with a boyfriend.But now that our suspicions have been confirmed, a juiced up Mcgwire raises some interesting questions. What, exacly, was he taking? Did he stop using after he left baseball? And is it possible that the greatest slugger of our generation was a full blown addict?
