Wilder will take the rematch, 100%. No way he's gonna refuse it and inflict even more humiliation on himself. No one wants to see it but I can't see him backing down unless they agree to 'postpone it' till later.
AJ will come through Pulev. He's a nobody in the grand scheme of things. He isn't a puncher and has only ever fought once at elite level and got pummelled by an ageing Klitschko.
Either way, AJ doesn't stand much chance against Fury. His chin is the worst of all the big heavyweights.
