So far he’s faced 3 top 10 opponents and 2 have gone the distance. Right now he is more in the company of guys like Charlie Retzlaff and Cleveland Williams. He can be called champ because of belt proliferation but in fact he never fought Wlad- so I put Fury and Joshua above him. So to me he’s a big puncher not yet proven at elite level like guys like Tyson, Foreman
Unproven, couldn't even knock out a fitter Stiverne who was defending with his face. He hits hard but most heavyweights do. Joshua would have a similar KO% if he faced the same level of opposition as Wilder. He needs to face more world level opponents and knock them out before he can even be compared to the greats.
He's with that group. Difference between those 3 you mentioned is that they can land big punches on top opposition constistently, whereas Wilder cannot. He just lands the occasional shot and gets lucky. Power of all 4 is pretty much equal. But there is a gulf in technique that separates Wilder from that group.
Wilder has very good power, but it's definitely overrated. Stiverne went 12 rounds, he couldn't drop or KO other stationary targets Duhuapas or Arreola either, thus I doubt he would be able to drop or KO guys with rugged chins like Whyte, Miller, Povetkin, Chisora or Parker. Wilders power looks outstanding because it has been a highlight against guys with less than desirable chins. Of his other opponents, Szpilka was also stopped by Kownacki, as Washington was steamrolled by Miller, Molina destroyed by Joshua, Ortiz has avoided big punchers his whole career, and T.Fury completely changed his style after being dropped by the likes of Pajkic and Cunningham. Wilders power is nothing like Tyson, Foreman, Shavers or even Joshua, but more like Tommy Hearns, has the same whip cracking leverage from a similar frame that stuns rather than the beat em up high torque Tyson or Joshua power, or the stone dropping on your head power of a Foreman, Shavers or Browne.
