I think AJ showed v Whyte that he is ragged when he gets angry and I agree that Fury has all the psych skills to wind opponents up. AJ would have a struggle trying to stay calm and focussed.
Fury's about the only fighter in the boxrec top ten that I'd consider PED free. But to be honest, I wouldn't be surprised if he pissed dirty as well.
People need to understand that at that level no one is beyond suspicion.
Tyson Fury said in an interview that ALL fighters do it. He didn't bother asserting that he had never done it.
Hard to know what to believe when he speaks though!
