Shields stand up was really much better than anyone expected, he landed some nice shots.
at some point I'm sure GSP really doubted because of his eye and the fact that he realized that he was not going to
1. KO Shields
2. do anything on the ground (he was really struggling when he took Shields down and got up immediately)
he fought through the 3 remaining rounds, still clearly dominating 2 out of these 3 with one good eye and the other one apparently very seriously hurt.
I mean when you're one of the greatest and you realize you have a potentially career stopping injury (he was panicking, you could tell seeing his eyes, he was close to give up and went back only on faith, his corner words were perfect too), you still have 3 rounds to go with an opponent who might as well get your injury even worse.
how many fighters would have given up in this situation, Kos looked like a child back in 124 and couldn't do anything, GSP won the fight and everybody could then see how serious Shields was as a contender.
now I want to see Shields against serious opponents like Kos, BJ, Fitch, Sanchez etc... and I really would like a GSP/Shields 2 (more than the fabled GSP/Silva that might just not gonna happen, GSP knows he can't win against Silva, not right now, he's getting there but Silva might be retired when/if he ever gets the skills to beat him)
Shields could have won this but I think GSP, even with the injury going on, showed the biggest heart of the two.
The fight in itself wasn't exciting "per se" due to the injury I believe, but GSP showed the true heart of a true champion, he clearly won, it wasn't some arguable decision.
And Shields was undoubtedly the very best contender in a long time. props to both fighters on this one.
