Ali Louis Foreman Liston I'm supremely confident that they would beat him. I'd also put my money on Dempsey and Marciano.
Lewis and Tyson are the two best heavyweights in the last quarter century with Holyfield in third. Where's your list Van? Here are the guys who give Tyson the toughest test. Guys in bold and underlined are his toughest at 50/50: Louis Liston Ali Foreman Holmes Holyfield Bowe Lewis Vitali However, the only one who should be favored over Tyson is Ali. I don't think Ali has enough firepower to get the job done. You need power, speed, chin, stamina and fluidity.
As usual, you don't favor anyone over Tyson. How typical. Ali had the "firepower" to knock out a peak Foreman. The only man to do so. While a prime Holyfield couldn't knock out an old Foreman. But a past it Holyfield was able to knockout a certain ******. :rofl Other than that, a very decent list. Of those you listed, I'd only favor the first five.
Here's a list of those who l think could beat a prime Tyson Louis Dempsey Marciano Liston * Ali * Foreman (70's version)* Holmes * Tua Douglas Lewis * Holyfield * Bowe * Vitali * Wlad The fighters with * beside their names have a 50-50 % or greater chance of winning. Of those 8 fighters l would give Ali, Holmes, Liston, Foreman, Bowe, Lewis and Vitali a greater than 50-50% chance of winning. As for picking Lewis his chin was fine against Tua, Holyfield × 2, Mercer and Vitali so while it could be a deciding factor, given Lewis' skill set his supposedly weak chin is unlikely to determine the outcome.
