If Joshua sticks to his fundamentals and doesn’t look for the knockout, I’d favour him, but he’d be silly to start trading with someone like Williams who can shorten up his punches, is quick and has power, and a better chin than Joshua.
AJ by KO. That being said, pirme Williams was a very good boxer actually, and a hard-hitting too. But AJ is better overall and has a huge size advantage.
AJ by lights-out KO. Williams is a little overrated. He built his knockout record against journeymen but never mixed well when he fought the top guys.
Williams would be game and give it all he’s got. Might make it an interesting fight. But in order to win he’d need to land something big and early. Not sure I can favor him.
