I have been saying all these things about Conor's cardio for a while now; how he seems to breathe hard even in very short fights, how he was slowing down vs both Max and Chad. No one believed it at the time.
I agree, but I do think a fair number of people saw and put a question mark on it. However, it was next to impossible to have a legitimate discussion with all the fanaticism going on and the fact that he was ending fights early enough to avoid a proper read.
I think the Mendes fight was the most interesting, because he did slow down, but he also wasn't very active from his guard on the bottom, where he looked like he was trying to conserve energy. It's really unfortunate that Chad ran out of gas as quickly as he did, otherwise it would've been an interesting fight to watch going into the 3rd.
Like many champions who storm through opponents on the way to the title, it's usually the easier part. Once more data is out and they've faced some adversity, you see where opposing camps start to focus on those weaknesses and really exploit them. Depending on how McGregor adjusts, it will be interesting to see if challengers opt to weather an early storm, then shift gears in later rounds to beat him.
To his credit, McGregor has shown that he can be very introspective and self-aware, though. I recall during the Siver fight, he wanted to beat him within two minutes, but when that wasn't going to happen, he didn't force it. He maintained a fair pace, chose his shots and neatly wrapped him up during the second round. So he definitely has the fight IQ, but Diaz did an excellent job drawing him into his type of fight.
I think pairing him with Edgar, next, would be a very good test for him.
