Silva has said in the past he and Jones would never fight because of there friendship. Of course big money could change that I'm sure.
Silva's natural weight class is where he is now. He doesn't have to cut weight when he fights at 205, so he gives up some weight on fight day when he moves up.
Jones is a big 205 and would have a strength advantage, but I still feel Silva would knock him out with his sick striking.
I would like to see GSP move up to fight Silva. Silva would make GSP look bad, so no way Dana will let that happen to his favorite money maker.
I acually think Silva, Jones could beat any heavyweight in the UFC. People though I was crazy when i told them I though Silva could beat Fedor. Then what happens 2 weeks ago...Dan Henderson knocked Fedor out in the second round. Silva has already submited Henderson in the second round.
I think Jones vs Silva would be the biggest UFC fight to date. If Dana will throw out the big bucks it could happen, and sure hope it does.
