Sparring & fighting are two different things. A few weeks ago I was sparring a guy who has boxed for the Aussie National Team & pretty much caned him round the ring. But, being honest with myself it means absolutely fuck all with regard to me ever beating him in a fight (which the formlines would certainly be in his favour). Everyone can have a bad day in sparring, there's a reason the best are where they are, because they make sure those bad days don't fall on fight night.
