Ezzard Charles. I would say Jersey Joe at his peak, but he was more of a cruiser. Michael Spinks if he could avoid being hit clean.
That seems to be the common misconception with Foster. Ultimately he failed at heavyweight but he beat Bert Whitehurst and Willie Besmanoff who were reasonable heavyweights and technically over a dozen more at heavyweight including guys up to around 205 pounds.
Some light heavies could have defeated Lyle. I definitely would favor Charles over Lyle. Archie Moore as well.
I would give Gene Tunney a chance against both men. Liston famously had trouble with boxers who could move with agility and think on their feet. He was also susceptible to a well-timed right hand shot. Guys liked to try to time Liston's jab with a right counter. A couple succeeded. As for Foreman, we know that Tunney had the conditioning and stamina to go hard for 15 rounds. Foreman wilted multiple times in middle and late rounds. He got a little smarter about conserving his energy during his late career. I maintain that Tunney was crafty enough to stick around until the late rounds and knock Foreman out.
I'd give Archie Moore at his best a shot against Liston, but not the best version of Liston. Foreman's chin is just too good no light heavy is going to be able to discourage him and withstand his return fire.
Untrue. The only one who he had genuine trouble with was the GOAT.... when passed his prime. He was an excellent adapter and handled movers very well aside from Ali. Name them. When did Tunney prove his durability against the likes of anyone near Foreman in power? And no a passed prime, rusty Dempsey (who very well might've knocked Tunney out had it not been for the long count) doesn't count.
Well,yes I have huge respect for Chris Byrd and I sort of get why you think he might have a chance against Sonny or Big George. However Liston and Foreman were probably the 2 most heavyfisted ATGs in heavyweight history. Plus both these ATGs,especially Liston,had good/very good technical skills.This wouldn't bode well for Chris.
