This is the 2nd time that these two will fight for the undisputed title in the lightweight division, Haney is already the undisputed champion in this division because he won in their first encounter and Kambosos is just contending again for the title. Well, I think many of us here thought that Kambosos will at least face another opponent in the same division before he pursue a rematch with Haney.
But he had the right to chase for his old belt so the decision of rushing it is on his side, though I also think that he will try to fight for another fighter from this division before chasing Haney but the rematch was schedule and it means that he wanted to try again, thinking that he might win and reclaim his title. We never know whatever his camp is planning, but if they think that he's really capable, it will be decided inside the ring.
I can't blame Kambosos if he chose to exercise the rematch clause quickly because I bet he cannot accept the fact that he was dominated and was embarrassed in front of his own countrymen, so maybe this time, he got another style of attack or at least prevent being dominated most of the rounds.
He needs to improve his fighting strategy, that humiliation happened in front of his own crowd so better to think of something new that Haney will not dominate him again, something that will put him in a favoring side, but we never know if there's a chance on him to do that with Haney.
