Mixed Martial Arts is one of the fastest growing sports across the globe. On Saturday night, UFC 94 was held in Las Vegas. The premier fight was a rematch between two of the leagues best pound for pound fighters, BJ Penn and Georges St-Pierre. Here is the lead UFC.com was selling fans on:

In March 2006, top welterweights Georges St-Pierre and BJ Penn fought for the division’s No. 1 contender’s spot. St-Pierre earned a razor-thin split decision and went on to win the Ultimate Fighting Championship welterweight title. Penn dropped to the lightweight division and won the organization’s 155-pound title.

Now they’re about to do it again. But this time, there’s much more at stake. UFC lightweight champion BJ Penn looks to be the first fighter in history to hold two UFC championships at the same time when he faces Georges St-Pierre for the UFC welterweight championship at UFC 94: ST-PIERRE VS. PENN 2, live from the MGM Grand Garden Arena in Las Vegas.

Millions of viewers tuned in to Pay Per View to watch this fight. In 4 rounds, George St. Pierre was able to defeat BJ Penn by TKO. Penn is now 1-3 lifetime when fighting in the 170 lb class, a weight class he should never climb to again.

GSP’s win has brought about talks of whether or not he’s the best 170 lb fighter of all-time? He boasts an 18-2 record at that weight, but in my opinion needs to win more title defenses to earn the title of “best of all-time.” Matt Hughes may have lost his belt to GSP back in 2006, but he still holds a 43-7 lifetime record.

Who do you think is the best welterweight fighter?
