Was rewatching the first fight, I don't want to be an advocate for bad footwork but I think AJ needs to sit on his punches more in the rematch, was hopping around too much in the first fight, I think it took away from his power too. I know that if he stops hopping around he will be at a greater risk of getting stopped himself but it's his only way to win imo so worth the risk.
Can't defeat a great amateur like Usyk by trying to apply an amateur approach, that's like a home-field advantage for Usyk. Rather make it a dog fight. The problem for AJ is he isn't exactly comfortable in dog fights either, his defense falls apart whenever in the pocket, and gets hit with a flush shot. Robert Garcia might just be the right man to improve on this though so I like AJ's choice.
