Which Foreman? Young or old? Young Foreman bombs him out in 4. Old Foreman probably in 8 or 9, the action going much like the Qawi fight.
Foreman would probably get a TKO in a few rounds like Max Baer did only less slopily. It would be fun while it lasted though.
Two Ton Tony fought in an era where he carried a pretty significant weight advantage over most of his opponents. I believe this is part of the reason why Galento was able to remain vertical for the vast majority of his career, given his style, but he did have a good set of whiskers to go along with it. This advantage is all but negated against Foreman, who gives up only a handful of pounds during their respective primes. Galento was a big hitter, but Foreman would be far too much. Foreman TKO in the middle rounds.
I dont give guys like Sam Peter today credit for being "superheavyweights" and I wont do the same for Gallento.
Galento can hit, I suppose like he did vs Louis, he could score a knockdown if he landed right, but that sure wont stop Foreman from getting up and hammering Galento into defeat. Any were from round 1-4 before the ref calls a stop.
