Foreman would have stopped either Jerry or Oscar somewhat early. (any era). But, to give Jerry and Oscar a tad of credit, you're pitting their 74 versions against George with both of them past prime? pvp? Big Foreman could jab and Jerry couldn't box a lick and he would try to mix and get caught early, maybe cut. This fight ain't going deep. Bonavena? 5'11 tree trunk? If you think George was awkward look at Oscar. Probably an end result similar to Chuvalo, beat to a ******* pulp.
