Is he overrated ? yes
Is he an average fighter? absolutey not
you act like fighting nate in a different weightclass is easy money, which tells me everything i need to know about you.
His whole way up to the top was amazing, he predicted the outcomes like nobody else, he didn't just predict the outcome, he picked the rounds. His standup game was almost flawless, he was a fucking sniper in his prime, having one of the most accurate standup games i have seen in ages.
Also the most entertaining athlete this planet has seen in last decade, not even the great chael sonnen could've stand a chance against conors mental warfare in his prime.
Khabib is and will always be a terrible matchup for him, the only grappler he beat was mendes and he almost lost that fight as well, but when did he ever lose a stand up fight? People know how good conors stand up game is, so they go and try to abuse him on the ground.
In the end of the day, he is one of the greats, not a top10 fighter, but top1 in terms of impact and level of attention he brought to the company and the sport. 2 division champ and most influencial mma fighter in the history of the sport.
