I think the outcome would be different if Haney is a knock-out artist as he will be the aggressor and prone to Kambosos' counters just like what happened to Teofimo Lopez. Haney's style has brought him this far and the only downside of his style is how to draw a large crowd to watch his fights because, to be honest most of the fans are not excited to watch his fights.
And that is the ironic part of it, Haney is now the man, accomplished so much already and yet he didn't get the respect and recognition he deserved because of his style because as you have said, and I agree with it, that Haney's style if very boring or at least he doesn't have the persona that you hate him that's why you will go and watch his fight because you want to witness him getting knock out. On the other hand, the brandish style of King Ryan and Tank Davis is what the fans wanted to see. That's why even though they don't have any regular belt, their fight will made a lot of money and hype as compare to Haney defending all the belts against Kambosos the 2nd time around.
