from the beggining you could see mirko was just afraid to go for the kill, he needs to fights like a hungry man again but oh well, in his age, its hard to get this feeling back, he just doesnt need it anymore.
mir was holding he agression too but it seemed it was part of a plan, not product of fear. And he was pressing the action and going foreward all the time.
and how did the fight end? look, sports are, before being a form of entertainment, a game. Strategy plays the biggest whole and sometimes patience is the key. Anyway, my point was that Mirs attitude during the whole fight seemed deliberated while Mirkos not.
