Anyone that could have the reach and glove control to foil George`s posting defense and glove control, AAli controlled Foreman`s gloves well in Zaire, that`s how fighters have to fight George, but they don`t have to rest on the ropes and woud be ill advised because Ali had the chin to do that, a fighter like Fury would have been difficult for George because he can exploit his reach really well and has good movement, Wilder has the punch and the reach to beat George and he`s quicker. Mike Tyson was a better fighter than George but having short arms and coming forward would make their H2H a lottery.
More so Vitali because of his power, reach and chin, Bryd didn`t throw enough shots and if he did I feel George would be all over him.
George had a lot of strengths and the older version of him fought around his weaknesses, the younger version was a wide puncher that gassed pretty bad if he didn't stop you. George first 30 opponents were basically cannon folder and he was very protected coming up. Remember this was an Olympic gold medal champ and that means there is talent in there, but besides talent George had heart and power. When George fought Lyle I was surprised he was hurt by so many right hands - Ali KO'd George with a right hand and Young put him down with a right hand. Still you had to get past early rounds and you had to avoid his power- Peralta did it against a younger version without falling and Dwight Qawi at 5'6 and late in his 30's survived most of Foremans early power by getting close against an older Foreman- Dwight was not a puncher like serious heavyweight punchers but landed more than I expected, yet Frazier far from his top form walked into everything george threw ( Frazier was rocked in his 2 previous fights against Terry Daniels and Ron Stander) so Joe was not near the form of FOTC but still got up6 X and was standing but nearly dead when the fight was stopped Foreman in both careers Young and flawed and Old but stronger, smart and more conservative and economical and relaxed So I guess there were a few ways of beating George but the hardest part was doing it because only a few did
