It's very possible (likely?) that the majority of guys who used steroids will never be fingered in the way players were in the Michell Report, BALCO investigation, books, and other media reports. That could change if a bunch of positive tests are unsealed or revealed ala ARod. That being said, it's still a little surprising that Sosa hasn't really come up in any of this given that he's right up there with Bonds, McGwire, and Clemens as inviting targets to out. But I still think he did 'em.
