It cracks me up that some guys didn't vote for Bagwell because he might have done steroids. Guess what? Alomar played in the "steroid" era, Ripken, Nolan Ryan, Andre Dawson and others did too, but you voted them in. I heard a stat on Raines that he was on base more times than Tony Gwynn. Dave Parker is criminally underrated. If you let Rice, Cepeda, and Perez in, you should Parker in as well.
Over time, I think they'll get in. Good or bad, these guys had major influence on the history of the game. McGwire/Sosa DEFINED baseball for awhile and brought it back from the scrap heap. Bond's numbers were absolutely ridiculous, drugs or not. Plus, a personal pet peeve of mine is that only the good players get vilified, while crap players who used PEDs like Randy Velarde, Benito Santiago, etc. all skate.
Recent inductions to the HoF like Rice, Puckett etc. have really dumbed it down. I'm not saying they were not great players, but the Hall to me is for the very best, and they were not. Your point is correct, if they're in, why not Parker, etc..
