Which 1990s Heavyweight Struggles Most In The 1970s?

Wlad Klitschko - his first 32 fights were in the 90s, he'd never make it undefeated coming up in the 70s.
John Ruiz - would never be champion. He couldn't get past the 70s fighters in the first 39 fights of his career.
Douglas
Rahman
Seldon
Norris
Cooper
Donald
Puritty
Grant

 

I think Wlad rules the 70s.

 

Old Foreman maybe. He was carefully managed in the 90's.

 

Yup. FOC Ali and Frazier best him I think, but after 71 he cleans house. Styles making fights maybe gives him a chance with the FOC iterations of both but I'd say he more of a chance of beating Ali that night than Joe. Joe was a force of nature that night and would not be denied. But yes. Wlad at his best likely cleans house in the 70s with that one caveat....


...an unpopular opinion I grant you, but somebody asked...and I'm all about cats and pigeons.

...but...Wlad was very big, very athletic, had two careers one when he was defensively prudent and one where he was less so. He had massive power and could box and negate in fighters. I think young George is made for him...

 

He beats them all rather easily.

 

Wlad hasn't the power? Really? Not according to Manny Steward who said he punched harder than any heavy he ever worked with. He bounced around midgets just fine, thank you.

 

Ali kinda sucked in the 70's.

George was tiny compared to the monsters Wlad fought.

 

50/50 with Ali, beats Frazier and Foreman.
