It's a marketing thing. Baseball clings to the past like no other sport. Any top 25 list always heavily leans to players pre-1980 and often features black and white film where players are sped up awkwardly. If you put Ohtani on the 1927 Yankees, he'd outhit Gehrig and Ruth. If you brought 1927 Gehrig and Ruth to the 2024 Dodgers, they wouldn't make the All Star team and maybe not even get a starting spot on the Dodgers. The players now are better than they've ever been. Send Houck back to the Dodgers of the early 60's and he's neck and neck with with Koufax.
