I would choose to see a brutal KO but not betting on it. You know, Haney is just too smart and that's the reason why lots of fans are hating him due to his style, like Shakur, they don't bring the excitement that is expecting for a boxing fight. Haney being the heavy favorite, I think Prograis felt disrespected since he's the champion, that's why he wanted to knockout Haney to prove to the people that he owns the throne.
I hope he can, he is highly motivated based on what we saw on their face off he really hates Haney, but that's what Haney wants you to feel, to hate him so he can use that hate against you, we have seen that happened on many of his matches, especially on Kambosos, he just waited for Kambosos to pour so he can counter.
We have a saying style makes a fight, even though Haney is the challenger I don't think will bring the fight to Prograis, only if he sees that he can take Prograis fight.
For Prograis to win he should dominate the early rounds or knock him out because Haney is good at accumulating points, especially in the latter or championship rounds, he should take the fight to Haney and try to take away Haney's game of hit and run.
For Haney to win, he will just wait for Prograis to make mistakes and pile up a lot of points Haney may be a boring fighter but his style is guaranteed to win the fight
