he has ONE loss at LW ever and he has taken on the best. To not put him in the p4p is wrong, he hasnt lost at LW since UFC 35 (i think to pulver??)
counting losses vs machida, GSP and Hughes would be like GSP moving up and losing to Silva. Losing to a legend that is a weight class above you proves nothing, just like if GSP went anorexic and fought at 155 he would lose, would that take away from his p4p??
