silva has palhares,falcao,santiago,stann,sonnen rematch,bisping and maybe lombard if he ever signs with the ufc. he has plenty.
gsp has diaz,story,ellnburger,macdonald,condit and rocha if he gets better stand up.
Falcao, Stann, Ellenburger, MacDonald? These guys aren't even top 10, none of them are even on the radar. Not sure what you're talking about.Aand you keep talking about "if Rocha gets better stand up", like it's a statistic you can put on the back of his baseball card. The dude just lost his last fight to a guy not in the top 10 with skills not even CLOSE to GSP. He's so far out of the title picture it's not even funny.
There are people in the title picture at WW and you managed to barely list any of them. The title picture for WW looks like this
Rick Story vs Thaigo Alves May 28th
Nate Marquardt vs Anthony Johnson June 26th
Carlos Condit vs Dong-hyun Kim July 2nd
Jon Fitch vs PJ Penn TBD
Clearly winners of Fitch v Penn 2 were closest to a shot but they got scrapped leaving the winners of Condit vs Kim closest, but their fight is 2 months away, which would leave GSP on the shelf at least 5 months. This isn't unheard of for GSP lol, so I think this is the most likely outcome aside from the rumblings of a possible crossover fight with Nick Diaz.
Beyond that I believe the winner of Story v Alves fight will face the winner of Marquardt v Johnson later this year for a number 1 contenders match. This is likely because Fitch will eventually beat Penn by decision in their rematch and be denied a title shot.
