David Pinto goes to the place I think all discussion about PEDs has to go, but in a comment far down the page Keith Levenberg takes it one step further. Well worth reading down the page if you have set ideas about drugs and the games.
I was going to link to Deadspin’s sober speculation of the contents of the redacted information in the Grimsley affadavit (about him, not by him), but the link from the affidavit to Albert Pujols’ trainer, Chris Mihfield, is too tenuous. Anyone who has hung around with professional athletes in the last 20 some odd years (and probably longer) knows that all follow the supplements, vitamins, and enhancement products to some extent. Mihfield recommending a guy to Grimsley who had bennies is a far cry from a smoking gun pointing at Pujols.
But then I think we need a lot less hysteria.
