Yeah this really shows what he's all about. After the series came out in 1994 he could have conceivable argued that he wasn't aware that Al Stump made all that shit up about Ty Cobb. OK, mistakes happen. But then he came out with an addendum on the series called "The 10th Inning" in 2010, and after 15+ years of being called out for his faggotry, he still wouldn't correct the record on Cobb, so that shows the only thing that matters is the agenda.
He also single-handedly convinced a generation of people that the Negro Leagues were on par with the Major Leagues, rather than just an exhibition league with a few legitimate stars in it. That's not a knock on Satchel Paige, Oscar Charleston, Josh Gibson, Turkey Stearnes and maybe a few others, but the majority of Negro League players weren't major league quality. But if you listen to Ken Burns tell it, he rewrites history to make liberals feel good.
So I would imagine all of his "documentaries" suffer from the same corny narrative crafting.
