The Best boxer?

[Sophie Hart]

Who was the best boxer of the 70's - 90's???

mine is Muhammad Ali

[Zelley]

My view is ALI's best years were in the Sixties before the ROPE A DOPE years.
but selected as the best in the Sixties was Emile Griffith.

From 70-s to 90's I'd say Larry Holmes and George Foreman had accomplishments that would take some beating. (I think I'd pick Holmes over Big George).
