I think the idea that "walking Mirko down" was some easy tactic might actually beat claiming Fedor was a brawler for shear wrong headedness which is repeated by large numbers of people, more Rogan UFC brand spiel along with the idea that "Nog always took a beating".
In reality Mirko was an incredible counter fighter and destroyed almost everyone who tried to do that, Wand, Aleks, Herring, Igor, etc. People tend to focus on the LHK as something Mirko landed to finish when he was in control but he could land it against opponents pushing forward like Igor AND it ignores how effective his bodykick and left straight were, indeed I think in MMA those two may actually have been bigger weapons for him.
He doesnt do anything flashy like Anderson but people tend to overlook that Fedor slips Mirko's left so many times in that fight and along with blocking the mid kicks that was really key to getting the upper hand standing. On the ground again I think he exploited Mirko depending on his guard being so strong for defence, basically forced him to work so hard to maintain it stacking him up that it tired him out.
The Hunt fight honestly I didnt think Mirko looked at good in, had a leg injury and perhaps more importantly was still hung over from the Fedor loss, he didnt look good beating Barnett the second time either IMHO. Even then of course he still landed a plum LHK which probably finishes all but a tiny handful of MMA fighters and a very nasty axe kick.
