Featherfisted might be a tad hyperbolic but 1. I am fond of hyperbole depending on which mode I'm in when I'm posting. And 2. I needed a word beginning with F lol
AJ should win by knockout but that is the exciting thing about AJ's fights his chin isn't that good so any world class fighter has a chance of catching him and knocking him out.
Briedis has a granite chin, I don't see him getting knocked out by anyone. He has one of the best chins in the business, up there with GGG and Canelo. He's never been wobbled in his career and he sparred both Kltischko brothers many times without getting hurt.
