Yeah that's why Nate finished Conor in a round and a half in the first fight. Lol at anyone who uses the "being tired" excuse 7 minutes into a fight. Also, when your explosive AF, when you throw huge overhands over and over again and hop around in and out like Conor...your going to get fatigued! lol you don't get the best of both worlds unless your on roids and those days should be pretty much over or highly contained at least, now. Yeah Nate may be flat footed, but he conserves energy that well and he takes low kicks better than he used to. And checks some here and there which is why Conor was on crutches after the fight and Nate wasn't even walking with a limp at all. The style of punches Nate throws also allows him to conserve energy. Nate also does triathalons, it's not like he was born with this cardio lol he put in the time to earn that shit. That's an acquired thing just like good hands, kicks, anything.
Conor's only hope against Nate is doing good early and then hoping to stand up to Nate's iron will just long enough to survive.
