Just watched the fight now. Easy to be wise with hindsight, but it was entirely probable that this would happen - a puncher against a fighter. Wilder was never really at the races, and Fury gave him little time to reset and compose. It always helps when you seriously hurt your opponent early on too. Fury changing his trainer to focus on more power and attacking approach looks to have paid off big time.
When did Fury bust up Wilder's ear? It looked to me as though it happened before the knockdown in the third.
I think that Fury has too much ring craft for AJ, but I hope that it happens.
