Does it? Nate Silver:
The comparison between Bagwell and Biggio may be especially instructive. The suspicion that Bagwell used steroids seems to be based on a sort of stereotyping. Bagwell hit for significantly more power than expected based on his minor-league statistics, and grew heavier and bulkier physically. Slugging first basemen who played in the 1990s are automatically suspected of steroid use by a certain contingent of voters, while speedy middle infielders like Biggio are not.
If one were actually to look at the list of players who have been suspended for performance-enhancing drugs, it might call some of these assumptions into question. Among these players are the utility infielder Neifi Perez, who hit 64 home runs in a 12-year career, the slap-hitting outfielder Jorge Piedra, and a substantial number of pitchers. The incidence of performance-enhancing drug use seems to be fairly randomly distributed between stars and benchwarmers, players at different positions and those with different skills.
Some writers seem to think they can profile steroid users, and some otherwise-deserving players seem likely to be denied a place in Cooperstown because of it.
