I don’t think you have to ignore PEDs. I think you have to look at it under the context of:
1. PEDs have been part of baseball since the inception and continue to be a part of the game. They are part of the fabric of the game whether we like it or not. Read any book about baseball from the 20s-70s and PED use was rampant.
2. In his specific era, MLB looked the other way, almost encouraged the use, and almost all players were using PEDs (whether that be needle use or other products). Even if they weren’t using a banned substance, they were using some type of PED.
3. Players who admitted to usage (or even were very strongly assumed to be users) have never even come close to what he was able to do in every facet of the game.
What he did showed the absolute pinnacle of baseball ability/achievement. He was the most entertaining player to watch while he was at his peak. The fact that he dwarfed all other players, who were using, in every part of the game (defense, base running, contact ability, swing decision, power) showed his greatness. He was almost 2x better than the league average player over his career and for a span of 4 years was 2.5X better than the league average player. He was the greatest player ever and we will never see anything like it again.
