Uh. Actually Sonnen is a Greco Roman wrestler. He has wrestled freestyle and has a viciouse double leg, but most of his wrestling accomplishments are in Greco Roman.
With Jones range and with the leverage he would have over Silva. I think Jon Jones would beat Silva easily.
If Jones can't find a way to get a hold of Silva then it could be trouble. With all the strange kicks and spinning moves Jones puts out... Silva would be prime for a counter punch.
That's about the only way I see Silva winning.
