If you want evidence Mcgregor is undersized for 170

[Perrichet]

But I thought Conor was going to win the WW title?

But, he was cutting weight for that fight and walking around at 187 minimum. Why would people lie?

LOL.

Can you imagine Conor at 185? Bodybuilder Mystic Mac, MW Champ, 2018! Luke Rockhold, watch out! That leprechaun is coming, and it ain't for no lucky charms!

Maia may finish in the first.

He might also stop the fight.

because he is one of those that hates to cut weight and has 0 fucks to give? his brother hates it as well which is why he went up to 185 despite having to bulk up and being horribly undersized

Or because he struggles with a bit. Not everyones body is the same - for some a weight cut is easier/takes more out of them.

This is very simple: Nate is a bigger LW than McGregor. However, Nate won via being the better fighter.
