I may get shot down for this but in my opinion, I truly believe that had Foreman fought Ali again he would not have lost. Foreman was a boy at 25. He was badly trained and so obviously dehydrated in Zaire and it was as humid as hell. I have a lot of love for Ali and he cleverly took his opportunity but I just think people write George off as some unskilled thug after watching the Zaire fight. This is so unfair and it overshadows some wins of genuinely epic proportions.
As a controversial note I put Foreman above Dempsey, Louis, Marciano, even Tyson.
However I do think the Galveston Giant would have caused him untold problems. Jack is the only HW great I would comfortably pick to handle George. But the ****e comments dissing the greats such as Tyson, Louis, Marciano and Lewis are just plain daft. All would have given Foreman hard fights.
