Yeah, I would bet dollars to donuts that Todd Helton never used steroids.
As far as the HoF ballot, I'd vote for Bonds, Clemens, Helton, Ramirez, and Sheffield.
Kent, Rolen, Abreu, Wagner, Sosa, and Schilling are all borderline at best. Not to say they weren't good players, but just not what I would consider legendary status. A player that could strike fear into the hearts of their opponents whenever they stepped on the field.
Vizquel is a conundrum. He was a legend on defense, but his offense was weak by comparison. And almost no one gets into the HoF on defense alone.
