Hmmm.... this almost flipped my prediction. I think you make fair points. In fights like this where people are trying to guess whose going to be more shot in the fight, makes solid predictions hard to make. I do think this fight has a big chance of being decided simply by who is pressing forward and being more active, not necessarily whose being more effective. In that sense I still favor Chisora here.
The problem I see for Wilder is not that his power is gone but he just can't get the shot off anymore. He takes to long to get set now because he is not as sharp and now that he has lost his reflexes all his flaws are on full display. I'm not counting him out but he needs to get that timing right.
Wilders power relied a lot on speed and quick flexes. He lacks the technique of great heavyweights like Wlad, Lewis and Foreman so he's going to struggle as he ages. He's also a confidence fighter so being physically and mentally ruined by Fury isn't helping matters either.
Wilder is completely shot but if Chisora presents Wilder with as many free shots as Wallin got in there fight but did not capitalise on,then there is a very good chance that Wilder will land something big ! Not a fan of this fight tbh as both clearly have there best days well behind them and don’t I want to see either of them seriously hurt .
