Neither would move much, Foreman's dream, but McCall likely had the greatest chin in boxing history. Maybe human history, like a giant Neanderthal. Foreman would batter him & win, but McCall would never go down.
Mc Call need to be at his best to defeat George. Mc Call at Bruno fight will lose. both have iron chin so the fights will end in decision.
Best for best i'd pick McCall. Foreman becoming crazy over-rated round here in his second career IMO.
McCall could barely beat a 45 y/o husk of Larry Holmes. . Holmes nearly won the fight with just his jab. Foreman of 88-92 would bash MaCall from pillar to post and might even stop him if Bull is brave enough to engage..
If George Foreman is in shape, this could turn out to be a good fight, remember Oliver McCall did defeat Larry Holmes in a very good contest to retain his title. I think that Oliver has a good chance to win this one on points, but if it was against a prime 1973 George Foreman, Foreman by a knockout. That Foreman did not give anyone a chance to set up, he smothered everyone with his wild haymakers.
