On April 30 at UFC 129, UFC Welterweight Champion Georges St. Pierre is putting his title on the line against Jake Shields. If you're saying "Jake who?" don't feel bad. The name might not be a common one to the casual MMA fan, but MF is here to give you a quick rundown on why this 170-pounder is a worthy opponent for GSP.

He's a winner
When it comes to winning streaks, few fighters can match Jake Shields. Undefeated since 2005, the 32-year-old Jiu-Jitsu specialist has racked up 15 consecutive victories in the last six years. St. Pierre can't make the same claim thanks to his 2007 loss to Matt Serra.

He's a proven talent
Since Shields has only had one fight in the UFC, it's easy to write him off as a guy who hasn't faced any worthy opponents. But that's just not the case. In his time with EliteXC and Strikeforce, the California-native has battled — and beaten — top fighters like Dan Henderson, Paul Daley and Jason Miller.

He's an innovator
A black belt in Brazilian Jiu-Jitsu, Shields has taken his studies in the martial art one step further by developing his own approach to the form. Eschewing much of the traditions of BJJ, Shields' "American Jiu-Jitsu" combines the takedowns and throws of collegiate wrestling with the basic submissions with the submission game of the original technique.
