The winds have changed now. In the first poll, only 30% thought the undefeated Usyk would prevail over Joshua. But now that Joshua has been convincingly defeated by Usyk although only by unanimous decision, 81% believe Usyk would still come out the winner in their rematch come spring of 2022.
I'm still giving Joshua a chance in their upcoming rematch. He was able to avenge his loss to Ruiz. He could also avenge this loss. But I don't think Joshua will win against Usyk by unanimous decision. Usyk has more punches to offer. Usyk is more accurate as well.
