Because there are fighters that will beat him that don’t get the attention that he does, Khabib or Tony, Kevin Lee.
Conor hasn’t fought any of the sharks at 155 he fought Alvarez (got beat up by Cowboy) and Nate Diaz (Couldn’t finish Nate)....He ducks fighters like Khabib, Tony and Lee, which is why he is overrated, he just hasn’t been exposed yet.
He is overrated because his fans think he can just run through these guys, there’s a difference, Conor is the next generation of fighting vs Alvarez and Jose Aldo are the last generation, I’m not taking away what he’s done, he has some good accomplishments but he hasn’t defended belts over and over (proving he is the best out there) and for the Mayweather fight, Mayweather didn’t fight the way he normally does, only blind Conor fans can’t see that Floyd let him punch himself out so he would gas out and Floyd could come in for the finish.
