The Babe did not stop pitching because there was no DH. He just didn't want to pitch any more.
Also, he never faced hard-throwing relievers, modern scouting, and - wait for it - black or latino players.
He would be great today. But Ohtani does not have "privileges."
He is without question the best player in the last 100 years. If you disagree, tell me who is/was better.
