First of all, Shogun won that fight.

Lyoto, as "elusive" and "technical" he is, and he IS an incredible fighter, has one weakness - he doesn't attack. He's a counter-puncher that Shogun had the kryptonite for. He picked him apart from the outside with kicks, covered up when Lyoto punched, and was kept off balance by Shogun's takedown attempts and strikes from all angels. Lyoto lost every round in that fight, something that's never happened to him in the UFC before. He was gassed, he was cut, and probably has broken ribs and bruised leg bones. in short: he was shown to be mortal.
