If he would do it then why doesn't he. There's nothing stopping him and I'm sure as hell the UFC would put any other GSP fight on hold for this fight.
He has asked for the fight.
Dana White has said it could be next.
GSP just said he wants to clean out 170lbs and he isn't ready for Silva talk.
What. On. Earth. Are. You. Talking. About?
You make no sense. Silva has asked for this fight every week since he beat Sonnen. Pay attention.
