I really think these two could really get into a chess match. I think Braddock could be really tough for Schmeling, since he was also a good counterpuncher.
I think the closest we have in real life is Schmeling vs Stribling fight, although Stribling was a bit different than Braddock of course
I don’t really see a different outcome. Apparently by this point Braddocks arthritis made it impossible for him to raise his hand above his head.
