I think his best strategy is to come in heavier and to try and knock Usyk out, similar to what he did with Wilder in the second and third fight. Even though it's risky, since Usyk has shown he's got a granite chin, and it may lower Tyson's speed and stamina, I feel like it's even riskier to try and outbox him again. With this legacy being on the line, it just seems too dangerous to leave it in the hands of the judges. Usyk is just too tricky of a fighter. It would also redeem his loss a lot more if he managed to knock him out as well, and might make a potential third fight unnecessary.
