Is it surprising that Georges St. Pierre is in the top two?
Although criticized for not being able to finish his last few opponents, there's no doubt that GSP is on another level than his competition.
The current UFC Welterweight champion has successfully defended his crown six times, most recently against Jake Shields.
But to be a great champion doesn't mean just wearing a belt, it's the journey as well.
GSP first fought for the title against Matt Hughes in 2004. Surrounded by a lot of hype entering the fight, he came up short, submitted via armbar in the first round.
Rather than mull over his defeat, GSP came back better than ever. He went 5-0 leading up to his second title shot, defeating BJ Penn, Sean Sherk and Frank Trigg on the way.
In impressive fashion, GSP TKO'd Hughes with a head kick to take the title of welterweight champ.
But the story did not end there. GSP would lose the title to Matt Serra in his first title defense, TKO'd
himself by the fellow Renzo Gracie black belt.
Humbled, he would take a year-long road back to the belt, taking the rubber match against Matt Hughes via arm bar to take the interim belt.
In his rematch with Serra, it was clear that GSP was the better fighter, stopping Serra with knees to the body.
GSP has proven himself to be the most well-rounded fighter in MMA history. His poise and ability to out think his opponents is what has led to him being such a dominant champion.
