James Toney vs 70s George Foreman (15 rounds) (unresolved)

I was trolling but I'll bite on this complete hypothetical I have literally no way of proving:

Corbett in his 1925 autobiography apparently said that Sullivan was just as fast on both his hands and feet as Dempsey. In that fight against George Robinson in 1884 that Corbett saw, newspapers estimated that Sullivan weighed as much as 220lbs. A 220 pound aggressive freight train with Dempsey's speed is a terrifying thought, Sullivan may have been shorter but he was stockier and may have been more durable as a result too. In his fight with Kilrain, long past his peak, Sullivan was estimated to be between 207-220+ pounds (in one newspaper I recall Sullivan claiming he weighed 248 pounds against Kilrain but I haven't seen a contemporary go THAT far lol) and he went for 76 rounds in that fight where he was also the one constantly pushing the pace in. If a dissipated, past prime Sullivan could go on for that long imagine how well a Sullivan from the early 80s would do. I already wouldn't count Dempsey out against Toney or George, imagine if he had an extra 30 pounds on him while maintaining his speed and style.

Just leave it to me to make a Toney-Foreman thread about John L. Sullivan lol, but carry on.
