Georges St-Pierre has stated that Jake Shields will be his stiffest test to date.
Shields left Strikeforce as their middleweight champion. He has not lost a fight since December 2004.
Since that loss, he has won 15 straight fights by defeating the likes of Robbie Lawler, Dan Henderson, Carlos Condit, and Jason Miller.
Now Shields will be facing his toughest test to date when he squares off against St-Pierre at UFC 129 this Saturday night.
St-Pierre has only suffered one loss since January 2005. He has beaten the best the UFC has had the best to offer. He has made solid fighters like B.J. Penn, Jon Fitch, Josh Koscheck, and Sean Sherk look like they didn't belong in the Octagon with him.
On paper, Shields may have what it takes to defeat the greatest middleweight to ever step foot in the Octagon.
Yet, there are questions that surround this fight that we will all have to wait until Saturday—and in some instances even later—to be answered.
