Age does when you become a beat fighter.
Mcgregor is not a top contender. He has only 1 fight at lightweight. Nor has he ever defended both of his belts against any top contenders.
Nate Diaz loses to all top contenders yet he beat mcgregor? Sorry dude but age doesn't have much of an impact on ufc fighters as it does with boxing. GSP is the perfect example.
Nate Diaz loses to all top contenders. Eddie alvarez is old and so is Jose aldo. They are all best fighters.
I wouldn't say easier fighters. You are basically saying aldo, nate Diaz and alvarez are easy? Mcgregor admitted he finds it easier to battle with shorter fighters who are primarily strikers. But Mcgregor wants money. He is actually quite smart in that sense. He does what he can to boost popularity and sales. I still feel like Jose aldo deserves a rematch but sad it won't ever happen.
