Pretty sure the result will be Haney wins by decision. In the first match, Kambosos couldn't touch Haney, and nothing will change in this 2nd match except for the increase of the KO probability because Kambosos will be more aggressive, which will make him out of his style. Honestly, this match is boring, unlike what we expected when Loma was the king. Hopefully, the winner won't chicken out when Loma is coming.
When he really wants to maximize the KO in this fight, the thing he has to do is clearly more difficult but indeed this is a choice because if he forces a fight with decisions then Haney is clearly the favorite.
In the first fight Haney already knew that Kambosos would play with speed so he held back a little, it was not impossible that he would also do something like this again in the second fight.
Kambosos better not aim for a single big shot to KO Haney. Haney knows that Kambosos will try to unleash everything in this rematch so I am expecting the young champion to become more careful which can make this rematch more boring. But if Kambosos can impose his style like what he did on Teofimo then maybe we can see a better fight than the first one.
There is no escaping for the winner of this fight because Lomachenko is the WBO mandatory. Haney also mentioned that he wants Lomachenko. Should Kambosos wins, he can vacate his WBO belt and give up his undisputed status if he wants to avoid Loma. But Kambosos earlier was scheduled to take Loma before the cancellation due to the war. So Lomachenko should be fighting for the undisputed belts soon.
I hope Loma still has it. He was actually the one collecting the belts one by one before that injury that caused his defeat to Teofimo Lopez.
