Well bro, it is almost universally accepted that Hendricks definitely won rounds 2 and 4, and GSP won 3 and 5. The debateable round was round 1 and it seems that everyone agrees that the round was razor close. This hardly qualifies as a "cooked" decision.
The medical suspensions came out today. It seems that GSP managed to blow out Hendricks knee in the first round with leg kicks. Hendricks is on medical suspension for 6 months. The talk is that everybody in the stadium (and likely the judges) heard that knee pop in that round...apparently everybody but Dana White.
So not only does it appear that the judges may have gotten the scoring correct as per the 10 point must system, but Dana declared in the press conference that damage is the most important criteria. If that's the case, not only did GSP win the round 1, but he won the fight because he's only on medical suspension for 45 days. His face will be cleared up long before Hendricks' knee will be cleared.
Face bruises don't count for everything folks.
