"GSP edges Perry by one higher profile fight at the same stage in their career?"
What the fuck are you smoking???
PMP fights one ranked fighter (not even top 10) and he loses a decision. At that point, GSP had already been a defending champion in UCC and had already fought Hughes, Parisyan, Strasser and Miller (ranked fighters) in the UFC.
Prime Hughes barely squeaked out the win over the up and coming GSP in their first match up, in a last second submission win (literally) in a round he was definitely going to lose. I'm not trying to rewrite history either... if GSP didn't fuck up and tap at the last second, he would've won that round easily on the scorecards. In hindsight, a rookie mistake he'd love to take a mulligan on.
In 27 months, PMP went 9-1 against scrubs and a journeyman model. In 27 months, Bones went 11-1 (yet another rookie mistake), and held wins over former champions Vera and the Janitor, Hamill and Bonnar.
Fedor fought Arona in his 4th fight and Sobral in his 7th.
PMP has done nothing to warrant being compared to these guys.... nothing.
