Commentators disappoint me.
Anybody watching that fight could see that GSP was running out of gas. Yeah, he won, but the "amazing performance" shit.. come on, he was very close to being utterly gassed and out of the fight. Bisping.. I've never liked to watch, but the dude was going to win the marathon, no doubt.
But instead, GSP gets in a good hit and that's it.
Now they build up GSP to be immortal and sell more PPVs based on exaggeration.
This is why a lot of people, including myself have tired of watching fighting. Because the fact is, it's 90% based on exaggeration. It's a game of very fine margins and to make out like these people are unbeatable is most often just bullshit. It doesn't pay to tell the truth that Bisping could well have won in the later rounds.
I agree about GSP running out of gas, but based on that flurry of strikes just before the choke, it was clear he got a second wind. If I had to guess, GSP would have found a way to go the distance and win by decision, had it not ended the way it did. GSP was winning the fight even while, as you said, he looked like he was running out of gas.
I also think you could really see the disparity in body weight in this fight. I felt that while GSP was successful with his takedowns, you could tell he was taking down a heavier man. I could sense that GSP was doing things that a welterweight fighter would not have had the body weight to as easily defend. Body weight helps in fights! I used to think it was all that matters, then thought it barely mattered at all - but yes, it matters quite a bit.
PS - GSP's face was really busted up [picture attached below].
What an amazing champion.
How did he win? Ko?
Technical submission [read-naked choke], He choked out Bisping after laying waste to him with a series of strikes.
