After UFC Welterweight Champion Georges St-Pierre throttled No. 1 contender Josh Koscheck in the main event of UFC 124, the most common question on fight fans' minds was an obvious one: What's next for the undisputed ruler of the 170-pound division?

The query isn't so much about who his next opponent will be, that much is known.

Barring injury, the former Strikeforce Middleweight Champion Jake Shields will be the next to run the French-Canadian gauntlet because that's what he was brought over from the UFC's rival to do. Only the date remains to be determined.

Nope, the question goes more to the heart of the matter, more in the vain of "who's left to challenge the champ?"

The thinking was that Kos was the perfect hybrid of wrestler and striker to pull the rug out from underneath Rush. Turns out, that was wrong. Very wrong.

St-Pierre jabbed Blondie in the right eye until the latter couldn't see out of it and then it was just a matter of whether Georges would be able to stop the talkative challenger (he could not).

And while Shields has proven to have a superlative ground game, he'll be a sizable dog heading into the tilt because of his perceived inferiority in the stand-up.

So the issue remains, who is left to push arguably the greatest welterweight champion the sport has ever seen?

Here's a list of the top 10 warriors who might still threaten Georges St-Pierre nearly unprecedented run atop his division.
