I think haye has worked with don king in the past, I think it's how he got the valuev fight(cant remember though) and seeing as don king pretty much owns stiverne just now, if stiverne wins I would not be surprised to see haye right up there in line for stivernes next defence.. Wbc seems to be having eliminators for the mandatory but they can easily be bought out :S

If wilder wins the wbc belt before haye can get a shot though, I think wilder would avoid haye like the plague and haye would have to work his way to a mandatory shot, which he might do, if he can be bothered.
