Tyson wins, but I think big George hangs in there for a while and lands some decent shots. His cross armed defense, two fisted attack, and ability to tie people up and neutralize attacks would make it a night's work for Tyson.
Prime Tyson punishes an old Foreman heavily. Even in his ring dotage,though,George had an iron chin so he'd last the distance. Mind you,his face would look like it did after the Alex Stewart fight.
Mike was Fine if he was able to hit an Opponent, and the opponent could not hit back and dispute the inititive, George had under appreciated hand speed and a Predators instinct to finish wounded prey, His final Left hook as Norton was Falling was impressive, And when he Nailed ****ey he finished him with a Hook on the Turn, If he Nails you, you got Problems, its his Foot Speed and getting into firing position that makes me fear for his competitiveness here, If Little Bloated Qawi can Give George a bit of a Tussle Then Mike should be able to Beat George to the Punch and Stay on Top, If he Lands a bomb like he did on Botha then Mike can cut loose and have a sympathetic Ref intercede, It might look a bit like the Initial Bruno Encounter, Honest Mike will state that he could feel George's superhuman Strengh and that he was glad he didnt have to come up against a Young George..
That version of Foreman, had one of the most dominant jabs in the division. Along with that he would use his still lethal uppercuts to try and control Tyson. Foreman would encounter some hard times, but if he survives the first 4 rounds, Tyson would start getting doubts about himself. Foreman would then slowly chop Down Tyson and stop him in 10 rounds....
Foreman's man handling would be the deciding factor, he'd control Tyson on the inside and unleash deadly short shots that would dismantle him.
If Tyson fights his usual come-forward style, he could end up like Moorer. It's far from a sure thing but the pre-Douglas Tyson should win over George of the second coming.
There's a reason why this fight never happened. Old Foreman would win! Tyson would be right in range and Foreman would just bludgeon him. Foreman damages Tyson more than Tyson damages Foreman, and Tyson goes down. Foreman by KO.
