As an amateur looking in, Tyson Fury seems to be quite clever - yes he's tall and quite ungainly but, he makes that work for him.
From what I've seen, his punch is weak for his size (I'd love to see him deliver something devastating but he doesn't/can't) so, I think he does his homework and stops everyone from fighting their own fight.
............ he's an awkward fighter with size and a half decent chin on his side and, considering the devision at the moment, I think that's enough.
