I think the best way to judge a player, by far, is to compare him to the players of his own era. It's not perfect, but it brings their achievements much closer together than just counting home runs, strikeouts, etc. There is no doubt, stats would have been impacted, and some missing players would have been very high on these lists, if not for segregation...which was a complete disgrace. There are plenty of other factors too, though, such as....how many career hits would Ty Cobb or George Sisler have if they had played on astroturf? What affect did expansion have on numbers...there were far fewer major league jobs available years ago. What if Ichiro had played his entire career here, how many hits, steals, runs, etc would he have? Exactly how fast did Walter Johnson throw? How many pitchers have moved up on these lists because they pitched after the invention of "Tommy John surgery?" How many hitters added home runs, hits, etc by playing a few extra years as a DH? What would the DH have done to the stats of the pitchers from prior eras? What if the mound hadn't been lowered? What if everyone had traveled by train? What if there were no teams in the Pacific Time Zone today, as there weren't in years past? What if the fielders of the 1920s had used the same gloves they use now? What if Ted Williams had played in Denver? What if Koufax had pitched 5 more years? There are lots of reasons why any player you want to name may have moved up or down on these lists, "if"....what we know for sure is, what they did, when they did it...the rest is up to the voter to interpret and choose. Personally, I think that's the best part of these things. If you think the guy who ate people alive for 5-10 years was better than the guy who was always good for 15-17 years...vote that way, and tell the world why....if not, vote the other way and speak up. Honestly...how do you or I know how Barry Bonds would have done against Cy Young, or vice versa?
