For those of us interested in how steroids have shaped the game, this BP writer has a lot of thoughts, but doesn’t draw any conclusions except for the obvious one: There are too many variables and too much we don’t know (like, who actually has taken steroids and when) to feel comfortably right getting too definite.
Most salient point, that even now there are plenty of performance enhancing drugs that won’t be detected by any drug screen.
Those who have followed the issue closely won’t find a lot new here, but it is a reasonable survey of what’s in play and what’s at stake.
