The four players you mentioned were SUSPECTED of using, but never convicted or punished.
What about Manny Ramirez, who was suspended for PED use and still got 100+ votes in 2020? And, come 2022, will Alex Rodriguez, who was sat down for more than a season, be allowed on the ballot? More importantly, will he be elected to the Hall of Fame?
I'd say that PED users, convicted and otherwise, have been given a pass.
PED guys have an interesting situation though. For most of MLB’s “steroid era” they weren’t actually against the rule, the PA blocked it. The first time they made PEDs against the rules there was no testing and no punishment schedule, so not REALLY against the rules. I think McGuire and Sosa were out of the league by the time roids really and truly became against MLB rules with testing and punishment. Can you really ban guys from the Hall for doing something that wasn’t even against the rules? Not to mention that there is the “steroid era”, it is a part of baseball history, you can’t really tell the story of the game without it.
And no I don’t think A-Rod will get voted in. Too many people thought he was going to “rescue” the home run records from steroid cheat Bonds, only for A-Rod to get busted. There was a lot of sadness around the game that day.
