MMA Fighter Rankings

Georges St. Pierre remains the best fighter in all of mixed martial arts, regardless of weight class.

There are arguments, to be sure, for other fighters, namely middleweight champ Anderson Silva or featherweight champ Jose Aldo, getting the No. 1 spot. Most of those arguments center around the fact that Silva and Aldo are finishers, while St. Pierre tends to win decisions.

I'm sympathetic to those arguments, but what St. Pierre does in his decision victories is amazing: In his four decisions as the UFC welterweight champion, the 12 judges have turned in scorecards of 50-45, 50-45, 50-45, 50-43, 50-44, 50-45, 50-44, 50-45, 50-45, 50-44, 50-44 and 50-43. It doesn't get more dominant than that.

So St. Pierre remains on top. Find out the rest of the Top 10 below.

What a wild, crazy, unpredictable sport MMA is. A few months ago the heavyweight fight everyone wanted to see was Fedor Emelianenko vs. Brock Lesnar, and MMA fans thought we'd be deprived of having one true heavyweight champion because Fedor and Lesnar would never fight each other.

Now Fedor and Lesnar have both suffered decisive first-round losses, and you'll be hard-pressed to find anyone anywhere who considers either one of them the top heavyweight in the sport.

That distinction now belongs to Cain Velasquez, who at UFC 121 erased any doubt that he's the heavyweight champion of mixed martial arts. You know that Velasquez is No. 1, and you can see how 2-10 stack up below.

When you're trying to rank MMA fighters, it's easy to say you'll just rank them based on who they've beaten and who they've lost to inside the cage. It's a lot harder to actually create the rankings when you realize that it's mathematically impossible to rank every fighter ahead of the guys he's beaten and behind the guys who have beaten him.

That's the challenge of picking the No. 2 light heavyweight in the world right now. UFC light heavyweight champion Shogun Rua is No. 1, but there are three candidates for No. 2: Rampage Jackson, Lyoto Machida and Rashad Evans. And there's simply no way to rank those three without putting one of them behind someone he's beaten, and another one ahead of a man who has beaten him. Machida beat Evans, Evans beat Rampage, and Rampage beat Machida. Any way you slice it, someone has to get ranked ahead of someone who beat him in the cage.

So who's No. 2? I make my choice below.

I didn't think Chael Sonnen was a serious threat to Anderson Silva, didn't think their fight would get out of the first round and didn't think Sonnen could even come close to backing up all that ridiculous trash talk he spewed in the run-up to their UFC 117 fight on Saturday night.

But while Silva did manage to pull off a fifth-round submission victory, I now believe Sonnen has to be considered the No. 2 middleweight in the world, and I also believe the next middleweight title fight should be Silva-Sonnen 2. No one had ever even come close to beating Silva in the UFC, and Sonnen had victory within his grasp on Saturday night. He deserves another chance.

You know Silva and Sonnen are the top two middleweights in the world. Find out about the rest of the Top 10 below.

Georges St. Pierre whipped Josh Koscheck for five rounds at UFC 124, bringing to 30 his streak of consecutive rounds won. Think about that: St. Pierre has fought the best of the best in the welterweight division, and although you can knock him for not finishing most of his recent fights, even the wildly inconsistent judges we have in MMA these days couldn't find a reason to score a single round against him over 30 rounds of action.

So when does that change? Jake Shields has dominated a whole lot of opponents himself recently, winning 15 straight fights including eight by stoppage and five by unanimous decision. But while Shields is certainly worthy of his title shot, it's extremely difficult to envision him actually beating St. Pierre, who does just about everything better than Shields. I could very easily see St. Pierre beating Shields by yet another unanimous decision, 50-45 all the way around.

And so as we rank the Top 10 welterweights in MMA, we're left wondering if any of them have what it takes to end GSP's reign.

No one can doubt Frankie Edgar anymore.

After Edgar beat B.J. Penn by unanimous decision in April, a lot of people believed that the fight was a fluke, that the judges erred, and that Penn was still the best lightweight in mixed martial arts. But now that Edgar has defeated Penn once again at UFC 118, there's no room for debate: Edgar is the undisputed champion.

Except that Edgar has one loss on his record, and that one loss is to Gray Maynard, who has been anointed the next challenger to Edgar's title. Maynard could make a case that he deserves to be considered the top fighter in the division, but unless he makes that case again in the cage, I'm sticking with Edgar at No. 1. The rest of the rankings are below.
