Joshua has been known for come back after a devastating defeat and that makes this JOSHUA vs USYK II exciting as when he fought against Ruiz for the second time. Their strategy works to beat Ruiz and if they can execute the same working strategy then he can easily regain back and might have the chance to fight Fury in his next match.
I think you can not really compare the fights and also the rematches of Joshua vs Ruiz and now Usyk. Back then it was a huge surprise that ruiz managed to win against Joshua and even managed to knock him down 3 times. Then in the second fight Joshua dominated Ruiz and won his title back in a relatively convincing way. If you look at Joshuas fight vs Usyk then the experts and also the fans were by far not so convinced that Joshua was the big favorite again here. This was mainly because Joshua lost his nimbus of being undefeated against Ruiz and of course also because Usyk is a much better boxer in comparison to Ruiz.
So i don't see Joshua as the big favorite against Usyk in their rematch.
The results of the poll now reverses. People are now rooting for Usyk this time.

This is no surprise as we have witnessed their first match.
Definitely, the odds will favor on Usyk on this re-match. But curious what will be the gap of odds.
Can Joshua redeem himself? In my opinion, Usyk will still emerge as winner here.
