Amir Khan was recently offered a chin transplant, they offered him Wilders mandible, Khan declined. :deal
Will be proven once he steps up. At the moment it's pure speculation(and blind hate) regarding his chin.
In all fairness to Wilder it is all speculation in regards to his chin. But the signs are there to suggest it's a very real possibility than he is hiding a glass chin. From the KO's in the amateurs, to being dropped by obese journeymen, being wobbled by jabs and being over protected to a title shot the signs are there but we won't really know until he fights for the title.
It's no speculation, it has been PROVEN to be drammatically weak. A light heavyweight knoccked Wilder OUT while having amateurs gloves (heavyer and softer, with more padding), and while Wilder had HEADGEAR on. That small skinny guy is so unknown that it is not possible to even find datas about his weight, heigh and reach. And yet he sparked Wilder out.
Wilder is a devastating KO waiting to happen. Why do you think his biggest name fight was versus the chump Malik Scott-feather fisted as they get. Wilder has a fraud record, and in no way deserves a title shot. Its just simply wrong.
It's not speculation, he's been KTFO'd with headgear on. Nicolae Firtha landed a jab on him that had him buzzed, Wlad repeatedly dropped him in sparring. His chin is glass, hence his unwillingness to fight a live body without a fix being in.
