A one armed and poorly conditioned Dillian Whyte gave Joshua heart palpations in Round 2 Whyte should've ended it in a similar to how Browne knocked out Chagaev; yet despite being injured and tired without a proper defense; he used his chin to remain until Round 7 to which he was caught from by an uppercut he couldn't see. 1. Took out Noniashvili faster than Chisora. 2. Knocked out Farkas faster than Duhaupas. 3. Stopped Sandor Balogh, which Erkan Teper failed to do the year before. 4. Stopped Tomas Mrazek faster than Chambers, Fury, Perez and Wach. 5. Stopped Nascimento in 2 rounds, something Fury, Chambers, Parker, Charr, Chisora and Takam couldn't do. 6. Despite being injured, Whyte stopped Brian Minto faster than Parker, Szpilka, Huck and Arreloa. His durability and chin was seen in general; as expected from an experienced kickboxer. As Peter Fury said, Whyte needed to work on his shape and it was a shame he didn't; would of been a different fight entirely, but as you said there were defensive elements wish he needs to work on, as well a leg and foot speed ~
In terms of being at the top of the division, yeah it is comparable. If anything Wilder completely out boxed Stiverne. Fury ran like a little girl, Klitschko was terrible. Wilder and Fury will both be belt less shortly so....
