This first pic was taken leading up the rematch with McGregor. Nate looks almost bigger than Nick who has fought at 185 and fought a 200lb, juiced up Anderson to decision. Much bigger than a guy who fights at 145lbs. Nate has filled out a lot and isnt the same guy who tried going to 170 back in 2011. His frame is definitely suited for fighting at a higher weight class than McGregor. I think McGregor got so tired in the first fight and so tired in the second fight (briefly) because that is what happens when you carry the weight of a tough fighter from a higher weight class who's whole style is built on pressure. Nate's best moments came from Conor being tired, not because he was outclassing him with pure skill and I think a big part of that was because of the size difference. I am aware if two men are the same weight they are the same weight but Im talking about their frame. A guy with Nate's frame isnt fighting at 145 and a guy at Conors frame isnt going to be fighting a whole career at 170. Conor is easily a weight class smaller and that makes a huge difference in a 5 round fight against a cardio machine like Nate.
