Exactly. These can be interesting discussions, but we will never know for sure how many homers Ted Williams would have hit, or know how Babe Ruth would would fare if playing baseball today.
Babe Ruth spent the first six years of his career as a pitcher. SIX YEARS! And you think YOU made a big mid career change? Of course Babe Ruth changed the landscape around 1920, so you are trying to compare Pablo Picasso to Rembrandt.
The young people think this wimpy baseball they play today is the same as the old days. You can’t even run into the catcher.
Bob Gibson and Don Drysdale would dominate these guys under the old rules. It’s the new rules that have wussified baseball, and I think the modern players do well with them.
I have nothing against Pujols. But Willie Mays was as good as it gets.
