well he's not enthusiastic about the idea because, and he said it, he has another fight to focus on, and this is the one against Shields.
What use would it be for him to blah about the andy fight while he's supposed to be preparing for Shields ?
I'm pretty sure all who now call him a pu**y would have called him "disrespectful" if he was talking bout andy while preparing for Shields.
haters gonna hate
That being said, I don't see GSP winning against silva, all I can see is him getting caught while shooting for a TD
I see GSP winning a rematch tho, but as it is now, I'm pretty sure silva would take him out just as easily he took out just about anyone else
