The thing with Jones is pretty similar to Silva; no one has really rushed him and been able to take him down to keep him there. Here comes Sonnen, first guy in UFC to have absolutely no regard to Silva's strikes, move straight through them and get him to the ground. I see the same thing happening with Sonnen/Jones, but we'll have to see how Jones reacts to being put on his back.
That's assuming he gets him down, though. Jones is going to fight from VERY far away and make it hard for Chael to even get in close. Then when he does, it's not going to be like Anderson Silva. Chael was most likely the stronger fighter against Silva, and this time he's going to be going against an (arguably) stronger, bigger, and more dangerous WRESTLER.
Running at him and taking him down isn't going to be an easy task. Especially considering, in this fight, Chael runs the risk of being stuffed and ending up on bottom beneath those elbows.
