Comparing his UFC record with this fight is ridiculous. He's never ducked a fight and fought all the legitimate contenders. Plus his skill at that particular sport is un-questioned.
I suppose you missed the two Nate Diaz fights. Nate was never a legitimate contender, as evidenced by the fact that Conor arbitrarily wanted to fight him because he had been likened to the Diaz brothers when he was coming up. Conor just randomly chose a weight and they made it happen - for money purposes of course - water bottle throwing pressers and all.
