The switch of trainers and move to the kronk gym makes it looks like Tyson is serious about going for the KO but after rewatching the first fight it's a sensible move.
What he lacked in the 1st fight was the ability to make wilder pay when he missed. The lack of physicality allowed deontay to stay dangerous for the full 12 without his energy being sapped in the process. The kronk gym has a reputation for an aggressive style but for heavyweights I think emmanuel Stewart actually turned Lennox Lewis and wvladimir Klitschko more defensively focused. He made them use their height and reach behind a solid jab and tie guys up on the inside. That's what Tysons gottta do, don't back up so much vs wilder, still be elusive but stop deontay from coming in and use his weight in the clinches to tire wilder out.
i think it's a good move. I was more confident of Furys chances going into 1st fight than I am going into the second but I still favour Fury slightly. The KO is possible but Fury on points is more likely
