Haye, Fury & Billy Joe; The UK style

What do you make of this fleet footed, manic, "herky jerky" style which has become a staple of UK fighters? Some would say it's an adaption of the hands down American style (Ali, Roy Jones), but it seemingly is something in of itself. Looking at Hayes fight with Wlad and Billy's fight with Canelo, they were similar in that when faced with a strong, conventional fighter, they fold under pressure. Yes Fury beat Wlad and made him look like a fool, but I think the size advantage clearly played a part. Do you consider Fury a fundamentally different fighter under Sugar Hill or is he still susceptible to a strong, conventional fighter that can apply pressure?
