If Fury does the same thing as the last time but still anticipates any changes in Wilder's fighting style, I am pretty sure that we're going to see this trilogy close with Fury as the winner.
Wilder did blame his costume, so I guess he will not change his style in boxing but will only wear a light costume so he will not be exhausted once in the ring. We saw the talent of Fury, if Wilder can't hit him, he would only loss his energy in the end and might likely suffer a defeat again as Fury has the power to KO him.
That would be a valid reason since we know how this heavyweight is prone to have less stamina than any other weight class in boxing. Anyway, that kind of reason is something educational because fighters who are in their weight class would not mimic what he did right there because obviously, whoever has less stamina before the fight will automatically be -50% on winning the fight.
