Wilder has not been knocked down in his career so far, therefore his chin should not be mocked for now. For all we know, he might have taken it. David Haye, Povetkin have eaten right hands from Wlad with ease without going down. Had Wlad been man enough to finish AJ this would be a very different discussion.
Molina could shake old Wildey with a sloppy, possibly accidental left hook, so Wlad's right hand would likely bury him.
