He has shown nothing but a great chin so far and great defence to defend it. If his chin gets rocked by Walters, it's because of Walters' intelligence and power.
Theoretically, it's possible, but there aren't any clear signs that would lead one to declare his chin as questionable, yet.
Think Loma's chin is good in all honesty. People we need to be looking out for: Deontay Wilder, Anthony Joshua, Luke Campbell.
As you are a new member, allow me to set you straight on a misconception in your post. The set of "more respected posters" and the set of "chincheckers" are mutually exclusive. That is to say, you can be a more respected poster or you can be a chin checker, but you can't be both.
Hate these stupid threads,"Dear members of boxing forum I've long suspected James Toney had an awful chin,what are your thoughts?" As double jab points you've run out of material and the thread has died a death,why not talk about how you like him
What he needs is a long trip to the fair shores of the United Kingdom. It helps to actually be born here but sometimes warrior spirit can rub off if you're open and willing to let it.
