I thought Wilder looked his age last fight and it's not gonna get any better now. At 35 Roy lost his reflexes and a slowed down Wilder will get dominated.
Where Roy fukked up at was going up and down in weight. He even addressed it a few months back.
After the Ruiz fight, he was supposed to stay at HW and sign to fight Mike but the deal feel through and instead he rushed back down to 175 to fight Tarver in nearly the same timeframe that he woulda been training to fight Mike. So not only was he training to fight but he was also training to lose weight.
