At the end of the day if Bellew fightscat heavyweight his next fight would be for a world title so there's no need fir him to fight Whyte in a final eliminator. I don't think Tony would beat the Champs (though would have a chance against Parker) at heavyweight but I think he would beat Whyte if they fought as Whyte is not a big puncher and doesn't have a big reach advantage on Tony.
I think Eddie Hearn sees Dillian fighting Breazeale next. Dillian definitely looking for a payday calling Bellew out, but I don't think it's necessarily the right fight for either. Although, I reckon it'd be a great build up for hype. Imagine the trash talking the two of them would do? Haha!
