I don't know, but I hope he stays at 205. There are so many great possibilities out there, and 205 is the most stacked division. I would love to see him take on Chuck Liddell, or Rampage Jackson, both of which are really good strikers. Chuck is fighting Rashad Evans in August, but maybe after that? I think Silva will have one more buffer fight against a solid but not great fighter before he takes on the cream of the crop at 205, maybe somebody like Keith Jardine.
After seeing Silva fight James Irvin, he basically said his loyalty is at 185, but he would fight wherever Dana White wanted him to. He would have so many more good opportunities at 205 though, and I hope he stays there.
