It's hard for me to wrap my brain around what Ruth was doing in 1920/21. It's hard to argue he put up the greatest statistical season ever, but for me.. the seasons that made a more lasting impact on me are the ones I witnessed.. like;
Foster in '77 - 52 HRs
Guidry in '78 - 1.74 ERA, 25-3 win/loss
Brett '80 when he hit .390
Hershiser in '88 with 59 scoreless innings
at the time, watching Big Mac and Sosa in the HR chase in '98 was the greatest baseball event I had witnessed..
