UFC 129: Georges St. Pierre is not going to be able to hold Jake Shields down

That's according to his head trainer, Cesar Gracie.

Shields will try to record his sixteenth straight win -- possibly the biggest of his career -- when he challenges reigning division champion George St. Pierre in the main event of UFC 129 this Saturday night (April 30) at the Rogers Centre in Toronto, Canada.

A lot of the talk heading into the "St. Pierre vs. Shields" pay-per-view event centers on the dominant wrestling and top control of the champion, who used his mat skills to neutralize the offense of past opponents like BJ Penn, Thiago Alves and Dan Hardy.

Can he stifle Shields as well?

Gracie doesn't think so and even tells the "Savage Dog Show" radio show that training for his star pupil is nearly impossible as no one can truly mimic his superior grappling:

"I’ve had some pretty good guys try to hold Jake down. It’s not going to happen. You can’t hold Jake down. You can’t just be on top of him and hold him. Superior grappling, I believe, is the way to win it ... I can see Jake putting a lot of pressure on this guy. You can train for Jake, but there’s really no one out there like him is the problem. It’s hard to get a guy that mimics [him]. You really don’t understand the feel of it until you train with him ... I just know that Jake has the tools to also win this fight. I think he can get it done."

Of course St. Pierre has also shown his ability to change his gameplan when faced with an opposing mat technician, like he did against Josh Koscheck in a five round title defense at UFC 124 last December.

"Rush" used a much-improved jab and superior stand-up to box his way to victory.

If the Canadian attempts to replicate that performance and keep the fight upright, all the grappling in the world can't help Shields, who's been criticized for his striking ability in the past.

And yet it hasn't stopped him from winning whoever they put in front of him.

How about it Maniacs, can St. Pierre hold Shields down? Will he even need to? Let's hear some predictions on where this fight takes place.
