The simple fact of the matter, GSP doesn't need to finish fights.
He researches the fighters he's facing and presents them a challenge that they can't handle, and then just wears them out over 5 rounds. If they have a great boxer, he fights them at kick boxing range and takes them down to the ground to ground & pound with elbows. If they are amazing wrestlers, he works on his take down defence and keeps them against the cages so they can't shoot.
The only reason he got hurt today was in the 3rd round when Nick kept on calling him a pussy and he decided to stand up for a while. And even then, I don't think he was really hurt, he just bruises easily nowadays it seems.
Honestly, I think his fights are still really good to watch. I love a technical ground game though or how GSP presents a challenge for his opponents.
Also bad example Heel, that was 20 seconds left to go in the 5th round. Most people don't do anything at the end of a 5th round when you're in the lead.
What's wrong with a points victory if it's technical and active? This thinking is why Wrestling is no longer an olympic sport.
Tabris, are you Canadian? GSP's performances are why wrestling is no longer an Olympic sport.
