This is boxing, not athletics, and a fighter's worth has always been proven in the ring. Are you one of these mysterious people hyping Wilder up? If so PM CableAddict. He'll be anxious to hear from you.
Fury isn't ready for Wilder. Maybe after 6 or so months working as a binman or in a petrol station he'll have built up the required skill level but that's unknowable at this moment in time.
He'll also have to stage a freak shoe and trunks losing incident, bribe all the major sanctioning orgs to drop him about two hundred places, and go inactive for five years. Until then he just doesn't pose the right sort of test for the young rising star.
