Just funny that he beat up a bunch of 155ers in his career...yet when it is "his turn" to be that guy...it is unfair...and "he may lose". And this and that.
What are you talking about? Sherk was a WW fighter when he fought GSP, he dropped down to LW later.
BJ Penn was fighting at WW and even MW before resigning with the UFC and fighting GSP at UFC 58 for the #1 WW contender.
The second time Penn was the LW champion and challenged GSP because he wanted 2 belts.
GSP has never beat up on a 155er that wasn't fighting at WW at the time, or wanted the fight.
Slight difference from this situation.
