I think Hasim Rahman would be very dangerous challenge for Wilder at that stage. I have no doubt Wilder would for for it thou. Deontay is not afraid of anything.
The WBC is only strict about enforcing mandatory fights if the challenger is a Don King fighter.:good
Charlie Zelenoff should get another shot at Wilder. Probably the only guy who didn't take a dive against him in the pro's.
It should be a unification fight with Wlad but the WBC doesn't want to give Wlad a complete monopoly on the heavyweight division. Doesn't matter though Stiverne will knock this batty boy out.
Accord to Boente, after the Pulev fight, Vlad should get a unification fight with the winner of Stiverne/Wilder next Spring....................Vlad by knockout!!!!!!!
