Inspired by the Ali-Charles/Louis-Spinks thread. The 33 year old Muhammad Ali of the third Frazier fight v Jersey Joe Walcott of the first Louis bout. And the Joe Louis of the first Walcott fight v the Thrilla in Manilla Frazier.
I see wins for JJW on points and a stoppage win for Louis (championship rounds) over a game but marked up Smokin' Joe.
I see Ali outpointing Walcott narrowly. If it had been one year on (1976 for Ali and 1948 for Walcott) I'd have gone with Jersey Joe by close points verdict. I agree with you about Frazier and Louis.
