Nonsense, the only accurate comparison is comparing your accomplishments versus your peers. (Jesse Owens' times in 1936 Olympics wouldn't make a high school team today, so his dominance over his peers doesn't count, huh.)
Also, Ruth didn't play against or with Black, Latin or Asian players, nor did he have to face specialists, like Closers and Middle Relievers.
He played against the best players available in the world at that time.
In those days, Pitchers went the entire 9 innings, so Ruth was facing the same old tired-armed Pitchers all season long.
Many would argue it was far harder back then. There were only 8 teams a league, so you were always playing against all-stars. There are so many teams now, half the pitchers today would barely have made the college team back then. Look at the eras of today's pitchers. Back then the mound was higher, and the strike zone enforced was armpits to knees. From 1970 to 2002 it was 1/2 to 1/3rd that size. The umps cherry picked HR pitches for the hitters to obnoxious levels.
Ruth was an out of shape lop who drank excessively and smoked and probably wouldn't even make a current Major League roster.
What are you smoking, he was 6'2" 198 solid rock for years, and regardless of his weight, his stats have no peers.
Ruth would have hit a lot more home runs if he'd only cut down on the smoking, the drinking and the sex, especially between the innings.
