Regarding the fight, I have read and see both of them going to the public and trying to hype the fight. Of course Kambosos says that it will be different in the rematch, but Haney is confident that George can't do anything in the second fight that might put him in danger or something.
That's their job if they want to sell this fight and earn their expected revenue, hyping the fight should make the fans believe that it will still be a competitive fight, or convince the fans that Kambosos has prepared something to beat Haney in this rematch.
Obviously, our bookies knows what's the real score, they made Haney a heavy favorite just like the previous fight and that will not change, unless there are significant reasons that will decrease the chances of Haney winning the fight.
