Ok ok, I don't want to argue whether he has the best chin out of any fighter. I'm not saying that he does. Maybe the Roy Nelsons/Mark Hunts of the world pip him to the post. The point is that he has a very very solid chin. Its part of his success. People once questioned whether Jones could take a punch. Now it is clear that he can - he has taken multiple big shots by Gustaffson and now Cormier. The punches never seem to even phase him, let alone rock him. Jones has a quality chin, no one can argue that he doesn't...and because he is hittable, with all his talent that is part of the reason for his success.
