Harold Scoiners is the obvious answer. Almost had his fraudulent ass out of there. Some would say Dusitn Nichols. I would say that if he got on a serious training regiment and got down to 350 pounds, it might be a possibility. Until I see that dedication, Scoiners is the answer.
I'm afraid it's not going to take a good HW to get Wilder out of there, he gets beat in his next few fights if he fights people of top 10 calibre (which he won't).
