Georges St. Pierre Streak: 4 wins Record: 17-2 Previous Ranking: N/A Big Wins: Hughes, Serra, Penn, Sherk, Koscheck, Parisyan The Canadian One is quickly making a case to be the greatest welterweight of all time. Georges has been unbeatable since dropping his belt to Serra - at no point in either recent fight (Serra II, Hughes III) did I believe Hughes was in trouble. His wrestling is better than collegiate wrestlers, his striking is as varied as it gets, and his will to win is among the greats. It will take a ton to beat GSP.

Josh Koscheck Streak: 2 wins Record: 13-2 Previous Ranking: N/A Big Wins: Sanchez Despite losing to Georges St. Pierre, which in and of itself is no huge defeat, Kos has been fantastic in the UFC. His top-notch collegiate wrestling background assisted his giving Diego Sanchez a first professional loss. Koscheck possesses one of the better chins in the game, never having been knocked out.

Jon Fitch Streak: 1 loss Record: 19-3 Previous Ranking: N/A Big Wins: Sanchez, Alves, Carter A previously lesser known talent, Fitch has quietly made his ascent winning fifteen straight fights, including a perfect run in the UFC. He hasn't been fighting fluff though; his streak includes a knockout of other top ranked welterweight Thiago Alves. Fitch's versatility on the ground and standing up earned him a title shot with Georges St. Pierre.

Thiago Alves Streak: 6 wins Record: 16-3 Previous Ranking: N/A Big Wins: Hughes, Parisyan The Pitbull shocked the world with a KO of Matt Hughes, but no one should have been that surprised. Alves had been 7-2 up until that point in the UFC and was just coming off a TKO of Karo Parisyan, a man who had previously never been knocked out. Alves' conditioning and killer instinct are among the best in the game and he should be in line for a title shot after Fitch.

Diego Sanchez Streak: 2 wins Record: 19-2 Previous Ranking: N/A Big Wins: Parisyan, Diaz, Florian After wins against Diaz and Parisyan, Sanchez was quickly hailed as the next big thing in the welterweight division. However, consecutive losses to Koscheck and Fitch took Sanchez down a notch. He got back on the right track with a win against David Bielkheden, but he'll need to get back into the upper echelon of competition if he wishes to move up in ranks.

Jake Shields Streak: 10 wins Record: 21-4-1 Previous Ranking: N/A Big Wins: Okami, Condit Shields is a veteran of just about every organization out there, except the UFC. That hurts him in these rankings. Like many of the other welterweights, Shields is a top wrestler, but his questionable strength of schedule in the last year keeps him out of the top 5.

Carlos Condit Streak: 8 wins Record: 23-4 Previous Ranking: N/A Big Wins: Trigg Condit suffers from a weak strength of schedule, but to an even greater degree than Shields. However, it's tough to deny him his place among the rankings: he's won seven straight and hasn't lost in two years.

Matt Hughes Streak: 2 losses Record: 42-7 Previous Ranking: N/A Big Wins: St. Pierre, Penn, Gracie, Sherk, Newton, Sakurai Where to start with Hughes? On one hand, he's probably the best welterweight of all time. On the other hand, he's lost three of four fights to all top opponents. His wrestling prowess and industry-best experience make him a constant threat at 170.

Matt Serra Streak: 1 loss Record: 9-5 Previous Ranking: N/A Big Wins: St. Pierre, Curran Just 6-5 in the UFC, Serra gained a too-high placement following his win over GSP. A subsequent loss, albeit a year later, sent him back down to his rightful place near the bottom of the pack. His losses to top competition and wins against subpar opponents ensure that Serra won't move far above this spot.

Mike Swick Streak:2 wins Record: 12-2 Previous Ranking: N/A Big Wins: Davis Swick's one of the most consistent fighters in the UFC, having suffered just one loss in the organization. He looked great against a decision victory over Marcus Davis.
