Jake Shields: When the cage door closes at UFC 129, no one can help Georges St. Pierre

Don't be scared, Frenchy.

UFC welterweight champion Georges St. Pierre will defend his 170-pound title against division number one contender Jake Shields in the main event of UFC 129 on April 30 in Toronto.

And like strikers who have the power to end a fight with one punch, Shields brings that same threat on the ground thanks to his world-class grappling.

But will it be enough to stop the St. Pierre onslaught?

To date, only former UFC welterweight champion Matt Hughes has been able to submit "Rush," when he took advantage of the starstruck rookie at UFC 50 way back in 2004.

Seven years later and all his limbs are still intact.

Shields is ready to make history, and according to his recent interview with IBN sports (via Sherdog.com), nothing is going to stop him. Not the crowd, not the location and certainly not his own weight cut.

"[The crowd] is a small factor but you can't let that stuff get to you. When it comes down to it, it's only gonna be me and Georges in the cage, no one else but the ref. No one is gonna help him. Yeah, the crowd is gonna be booing me and cheering him but it is what it is and something I'm gonna go out and deal with ... I made the (weight cutting) mistake once, I'm definitely not gonna do it again. I'm like 184 right now so it should be a nice easy cut."

Shields entered the UFC as the reigning Strikeforce middleweight champion and riding a 14-fight winning streak. He was matched up against top contender Martin Kampmann and although he struggled with a bad weight cut, walked away with a split decision win.

It was all he needed to earn a crack at arguably the best fighter in the world today.

 Of course fans and pundits alike give the Shields who huffed-and-puffed his way through his UFC debut against "The Hitman" little chance of dethroning the champ, but it only takes one mistake on the ground to end the bout.

No one will be able to help Georges when the cage door closes. But will he need any help on fight night?

How do you see this one unfolding? Five rounds of ground-and-pound for the champ? Or shocking upset for the challenger?

Opinions, please.
