If Anderson Silva meets fellow UFC champion Georges St-Pierre in a long-discussed superfight, Rogerio Camoes, Silva’s strength and conditioning coach, believes it should be at 176 pounds.

In fact, he feels St-Pierre, the UFC’s welterweight titleholder, would have a “considerable advantage” over 185-pound champ Silva if they fought at 170 pounds, he told MMAjunkie.com (www.mmajunkie.com) via email.

Regardless, Camoes said Silva already is shedding weight in anticipation of the possible stadium-show headliner.

St-Pierre (23-2 MMA, 17-2 UFC) and Silva (33-4 MMA, 16-0 UFC), the UFC’s longest-reigning champions, have been on a collision course for years. But following St-Pierre successful return from a 19-month injury layoff and his recent UFC 154 main-event win over Carlos Condit, the calls are getting louder for a challenge that’s bigger – literally.

UFC President Dana White, who stands to benefit as much an anyone from the potential mega-fight with Silva, has been one of the biggest and most vocal proponents of the idea. Granted, he deflected questions about the bout – which would likely be held in a major venue such as the 100,000-seat Cowboys Stadium – during a media call on Tuesday.

But with Silva unbooked for his next fight, and with the UFC not quite ready to commit to a welterweight fight between St-Pierre and top contender Johny Hendricks, talk of the superfight isn’t going away. And Silva, who’s already a super-sized middleweight, is busy preparing for a possible move down in weight.

“He weights 205 pounds now because he is already thinking about the weight cut to face GSP,” said Camoes, who works with the likes of Erick Silva, Rafael “Feijao” Cavalcante and Ronald “Jacare” Souza at X-Gym. “Anderson cutting about six pounds from the middleweight division and St-Pierre gaining six pounds from the welterweight limit would be a fair decision for both of them and to the crowd to see a great fight.

“It would be a crime Anderson Silva fighting at 170 pounds. He could hit that weight, but his physical decreases would be enormous. We’ve got to respect Georges St-Pierre, who isn’t only a fighter, but a monster, physically talking. If they fight as welterweights, GSP should have a considerable advantage.”
