Can't see Wilder having much more than a puncher's chance here tbh. Just feel most times Joshua would get there first.
Don't get me wrong Breazeale is terrible, he has not jab, too easy to hit, poor footwork etc. But his chin, power and heart makes him a dangerous style match up for a fighter like Wilder who if he goes in for the kill leaves himself open to be caught coming in. Watch the Breazeale/Ugonoh fight, Ugonoh for longer periods was handing his ass to him, so much so he got sloppy believing he had the fight won, but Breazeale stuck it out, took all the punishment but still fired back. I could see Wilder hurting Breazeale even dropping him, rushing in, then getting caught. Wilder has to outbox Breazeale, which he can easily do, but if he gets cocky and looks to take him out, he could find himself on the canvas. I'd still have Wilder a clear favourite but think he'll need to fight a more reserved style or risk getting drawn into a brawl where he would lose to the more durable Breazeale.
I agree. It's clear Breazeale isn't very good for the reasons you've mentioned. He's also incredibly slow. But Wilder could struggle with him as he can take a decent punch and can dish it out quite well as well. Don't think Wilder's particularly durable either.
