Anyone disagree if Seth Mitchell had fought all 30+ Wilder opponents he would also likely be undefeated? Not saying he is better than Wilder but Wilder, unlike any recent American Heavy has gotten a title shot without even once being at risk of being exposed. So still literally impossible to know how good he is or make an educated guess on result of next fight.
If to consider the toughest Wilder's opponent, they will be Malik Scott, Serghey Liakhovich, Kelvin Price, Audley Harrison, Nicolai Firtha. The last 3 are clear. - Malik Scott may have taken him to late rounds but he is less skilled and once in the fight would get caught. So it would be KO in late rounds. - Liakhovich may have won 1-2 rounds early in the fight but would have felt exhausted in round 5, so it would be KO in 5-7. The point is that Wilder has never been any further in a fight than 4th round. Both Scott and Liakhovich were knocked out from 1 punch in 1st round. He does have a tremendous power, but we will get all the answers in Stiverne fight. Personally, I am looking forward for that fight as I don't have any idea who would win.
Malik Scott may have beat Mitchell Liakhovich not. He was past it since the Valuev fight 2008 and will get hurt badly vs Ruiz jr
