Big George. Later in his carreer, he learned to pace himself, and willed himself to walk through punches. Wladdy has learned the pacing part, but...
Vlad is the best heavyweight in the world today, better skilled than Foreman, no contest. However, Valouev is the heaviest active fighter, who can weight around 330 give or take and is 7' 2" tall.
I agree that he throws a better variety of punches, and is much more fluid. But Farmy, the chin! The only guy who ever legitimatley put Foreman down was Lyle- ALi and Young were stamina problem. Wladdy is not so rugged.
The later version of Forman would be easily outpointed. Look no further than his points loss vs. Tommy Morrison and his gift decision vs. Axel Schultz.
If Wlad starts to get cocky vs. 70's Foreman, this fight is going one way. Once you hurt Foreman, he became a nasty *******. He'd get careless, wreckless even, but he'd be throwing those big bombs of his and he'd be coming after Wlad. He could find himself on the canvas - it's certainly not impossible - but he'd get up and tear after Klitschko again. Only a matter of time until George lands hard and flush, and once that happens, the game's up. I've never seen anyone back George up, and Klitschko would not be able to, imo. If Wlad playes it cool and tries to pot-shot George and diffuse him, he could win. But the minute he tries getting macho and throwing big right hands, he's tweaking the lion's tail.
If a journeyman ,a fat golfer, and a mediocrity can all KO Wlad, so could just about any version of George Foreman. Wlads been successful lately because the oppostition has been rather pathetic.The best guys that Foreman had to fight in his second coming, like Holyfield and Moorer, would smash Wlad. God, I don't even want to think about what guys like Ron Lyle , Jimmy Young , or Joe Frazier would do to Wlad. True, George had the loss to Morrison, but man against man,even the chubby 40 ish version of Foreman would destroy Wlad.
wlad would keep jabbin george an building up a lead the borin way as wlad does then at some stage he'll take a shot and go down then he will go down again in the round and then the ref wil stop it
as said above... 70's foreman by brutal KO 90's foreman would lose a wide ud getting his face jabbed off for 12 rounds.
