Haye would beat Price at the moment, Price does not have better ring craft , movement or sense of distance than Wlad and Wlad barely landed on a defensive Haye. Price would get countered and stopped.
Give it a few years, when he is less Green and he may do a number on Haye, but not atm imo.
Very good prospect, he should beat Fury pretty easily, Fury has good hands and decent skill but he lacks physical attributes, his power and chin are not up to standard. He would probably get walked down against any elite fighter, he doesn't offer enough offensive threat.
The NFL argument is silly. Football is not fighting. I can't think of any past great fighters that would have been decent at football, completely different skillset, so why the opposite. The demographics are different. You could just as easily say the same thing about Rugby and Soccer in europe, it's just an excuse that xenophobic Americans peddle.
