That would be a big treat for the boxing fans if we will ever see a Davis vs Haney fight. It's power versus a defensive fighter, we will see which fighter will win. But the fact that Davis are not agreeing with the fight yet AFAIK, that only tells that he understands how risky the fight with Haney is. He wants to maintain his undefeated record by fighting a boxer that he thinks he has an advantage.
That could happen as promoter are willing to fund that big fight since they are sure they can be profitable with their investments. But if one boxer which I think Davis does not agree with the terms
(his excused) then the fight will never be realize. So far, Haney's journey is more interesting as he is moving up and he not afraid to fight anyone, whether he is the one challening or the opposite thing.
Many are claiming that they are better than Pacman but they are wrong because all they care now is their undefeated record, that's why promoters would not like them if they can't bring a big fight where fans aren't sure which side will win.
Mayweather's style could be a model that most of the undefeated boxers are following. It's just a business on their side as well, and they need to protect their investment as a loss might also result to decline of value. Look at what happened to Ryan Garcia, he tooked a tougher challenger and now his value have dropped.
It's just one loss though for Ryan, and I think his stock is not affected by that defeat from Davis. On the other hand, it was reported that he will be having his next fight. But they are talking it slowly again, rebuilding Ryan's reputation at 140 lbs. But definitely, I'm seeing him fighting for a world title in this division, targeting the weaker, let's say Rolly Romero later.
As for Tank Davis vs Haney, might be very hard to set up as both wanted to be the A-side and so who will take less of the split? Davis has the selling point because of his style, but Haney has the belt and accomplished a lot in his young career and willing to take risk that Davis hasn't done.
