You're speculating about Conor, he could go much further, but being a world champion in any major organization at this point is out of the question. Many high level amateur and pros have given kudos to Conor's boxing ability, especially for an MMA fighter. Nate wouldn't have enough fast twitch muscle to beat a top 100 guy. He's just that slow, his shots lack pop (snap), and he's not heavy handed. His footwork just isn't there, he doesn't really understand distance well, his range control is certainly not very good and his timing isn't on Conor's level. His shot selection consists of the same old 1-2's, time and time again, like most MMA fighters. Nate doesn't even have good fundamentals, and therein lies the problem. He needs to learn how to enter and exit on angles because he squares himself up to his opponents often, including in some of your GIFs. As a result, he gets hit. What makes it worse is that none of these guys besides Johnson have decent hands (by "decent" that is for MMA).
I'm not even going to mention Nate's posture and how horrible it is. Look at Conor's and compare it to Nate's when they punch. Look at their mechanics and technique, foot positioning and so forth. There's a world of difference.
