Tunney has no chance. How's he gonna even hit Foreman? Foreman had a helluva jab. It was very fast. No way Tunney gets close enough to touch him.
If only Tunney had a resume at heavyweight to offer support for him beating a monster like Foreman. But he really has no resume at the weight.
Looking at it logically, Tunney could theoretically go the distance vs young Foreman pre title run, or post. If Young or Peralta can fight to survive, so can Tunney. If Tunney gives an inch, which I suspect he would, he loses. To any version of young Foreman, before Ali. He just can't take that power imo. He is an awful style for Foreman though, but that power and size difference is too much. Tunney was an ATG, he'd try and win. That'd cause him to lose.
Different styles. I'm not convinced that Jimmy Young would beat Frazier, yet Foreman dismantled Frazier.
I think that George Foreman, 1974 edition would jump all over 1926 Gene Tunney, ending it in round 3. Foreman's training duo of D. Sadler and Archie Moore would have watched hours of Tunney's fights. They would have watched Gene out box his adversaries by moving and firing his combos. George following his corner's instructions, comes out and tags Gene with a decapitating right hand which floors Tunney. Gene gets up groggy, and back peddles throughout the round. Tunney begins to appear gassed and has a panicked look on his face as a deranged looking Foreman starts to effectively cut off the ring, then in round 3 George catches Gene, pushes him off and connects with his whirlwind blows that have Tunney looking like he is being beaten into the canvas, Tunney takes the full ten count on his back with his eyes open, as the referee tolls the full count.
Why do everyone who watched Ali vs Foreman fight, automatically assume Foreman would gas if he had to go into the later rds with any fighter? Tunney was a great fighter, but he wasn't Ali. Tunney wouldn't agitate Foreman to a point of blind rage before and during the fight. It just wasn't something he would do. Ali won the psychological war, pushed Foreman to a point where Foreman's blind rage was so intense it made him fight possibly the dumbest fight in history, and wore himself out in the process. Only Ali could get under a fighters skin like that. I would expect Foreman to be much more measured and patient if he was fighting a fighter like Tunney. He would know Tunney would attempt to stick and move. But Foreman , based on how he fought, would push, pull Tunney off balance anytime he attempted to set his feet and attack, while he was off balance, Foreman would land some of the most powerful punches in boxing history. Tunney unlike Ali wouldn't be able to handle the immense strength and manhandling Foreman was capable of. (Ali was very strong on the inside, not as strong as Foreman but very capable of holding his own against him wrestling and tying him up.) Foreman would force Tunney to run all night in order to win. But he wouldn't be able to do that. Foreman would walk Tunney down, stop him with in 10rds.
