You never bet against a mayweather or a tszyu usually (barring V hatton IMO ) so I'm gonna take a nice comfy seat on the fence for this one, If someone said to me 'your god and you get to pick the winner' I'd pick tszyu simply because I think he's a great man and a true gent, but purely as a boxing analyst... I haven't a clue whether tszyu would land his big right or floyd would run rings round him. I'm stumped!
