With UFC president Dana White pushing the possibility of a super fight between his Middleweight champion Anderson Silva and Welterweight champ Georges St. Pierre, the MMA world has been talking hypotheticals for weeks now. Silva and his management seems on board with the fight, even eager, but they have been pushing the notion of a catchweight fight somewhere between the 170 pound WW limit and the 185 pounds Silva fights at at MW.

For his part GSP wants the fight at 170 pounds or nothing. This may just be a negotiating stance to angle for the lowest possible catch weight or it may be a definite drop dead ultimatum.

Don't give up though. Silva fought at 168 pounds several times early in his career in Japan and fought at 174 pounds as recently as 2006.

Even in 2010 he was talking up the possibility of moving down to Welterweight in the build up to his UFC 112 bout against Demian Maia. Here's what he told Yahoo's Kevin Iole:

He's not the type to call out an opponent and challenge a champion in another division, but he said after a news conference Wednesday that he is seriously considering a drop to 170 pounds for two fights.

One he'd take to see if he could successfully make the welterweight limit, and a second would potentially be for a Superfight with champion Georges St. Pierre.

...

"I'd like to test myself and I always love to take on new challenges," Silva said of his thoughts about a drop to 170 pounds from the middleweight limit of 185. "It's not that I want to go fight Georges St. Pierre for his title. There's no doubt in my mind that he's the reigning champion, the absolute champion, in that weight category. But I just want to test myself and see how I'd do at that weight."

There's also this video he shot for Heavy.com in which he talks about moving down to Welterweight or even testing himself at heavyweight. Watch from 5:50 to 6:35 of the video:

One day I'd like to test myself and see if my skills can make it in the heavyweight division. Who knows maybe one day I'll go down to 170 and test myself there.

GSP has been pointing out, correctly, that the 37-year-old Silva is looking for a huge fight or two to cap off his career but that GSP is still in the prime of his career and is neither willing nor able to play around with his fighting weight. Silva has always had an exceptionally malleable frame. Here's hoping he's willing to come down to meet GSP in GSP's own division.
