No doubt about that! Haney's definitely have the higher hand here in this rematch while Kambosos's chances are much lower compared to their first encounter. We saw how Haney schooled Kambosos that made the latter look like an amateur boxer, we expected differently but Haney's IQ will always prevail compared to Kambosos.
He's more prepared, and he knows how to play Kambosos I mean like what you said he schooled Kambosos by not letting him to make a close conversion which may lead him to win, Haney's style is more on defense and just throw punches when he sees good opening, but in terms of wasted effort Haney is limited in doing that, and if that will be the same thing Kambosos chance to push Haney to engage with him do have smaller chance.
Haney will just keep what he got and let Kambosos to try cornering him, but the defense will be solid and with his quick hands countering and throwing converted punches is where he will rely.
This might be against the majority idea but I do not think that Kambosos will be idle like that without any planning and change of strategy. I also think that Haney will be the crowd favorite but if Haney sticks to his boxing style during their first match and Kambosos found a way to crack it then we can probably be in for a surprise in this rematch. Kambosos is capable of that act since he has done it during his fight against Lopez.
