Have to put more thought into he little guys but at;
feather ...Sandy Sadler (sorry Uncle Pep)
light...Joe Gans (Benny Leonard)
welter... Sugar Ray Robinson
middle...Sugar Ray Robinson
LtHvy...Gene Tunney (Evander Holyfield)
the only one I'd bet on consistantly is Robinson! I'll say theres atleast 6 in all the classes that could fight one another and they'd defeat one another also! Ray.
