If Baer is operating in this Era, do Joshua and Wilder even have a chance, or would Baer smash them into obscurity?
Id be rooting for baer in this fight, infintly more endearing than the other two. Joshua and wilder move well which is bad for baer, Joshua stylistically would give him more trouble because he' more of a pure boxer while baer and wilder are sluggers, wilder largely had an unknwn chin but we have seen him rocked before. We all know baer had incredible power and one of the all-time best chins, if they try to move around and box like they should they should beat him, but if they try to go toe to toe with him they might get dropped. Especially if Baer came snarling at the mouth like he did against schmeling and carnera
Baer would be too crude and small for Joshua, I think. I suspect Wilder, who I don't like, would probably also win although Baer would be in with a good chance given Wilder's suspect chin and leaky defence.
I think Joshua would stop him without too much difficulty. Wilder is as undisciplined and as sloppy as Baer, both with big right hands. I'd tend to go with Baer as I think his chin would hold up better.
AJ's technical skill makes the difference, AJ picks him apart and stops him. AJ may have to survive a knockdown at some point to do it. Wilder wins if his chin can stand up to it. If it can't, then he's out of there.
