My thoughts on this are as follows:

~Based on Anderson's very uncharacteristic outburst I think Sonnen has got in his head

~Anderson's adjustment: Anderson is going to deploy much better footwork this time. He will move around a lot (in the first round esp) with the idea of landing some significant kicks to the legs and body initially than some strikes to the head; hoping to be able to capitalize on a big strike if he is able to land one. He will not attempt a lot of strikes. He will try to set Chael up and pick his shots from different angles. The idea is to keep Chael off of him early with minimal engagement. I think Anderson desperately wants to win that first round, even if its not that eventful, to prevent Chael's confidence from souring.

~Chael will keep moving forward no matter what and cut off the octogon even if it means he has to shove Anderson to the cage and pin him there al a Captain America style before he attempts a take-down.

~Chael will land some good punches but the stand up overall will favor Anderson because he will control it much better this time. Anderson will not dominate it however

~Anderson will get more aggressive in the middle rounds which will enable Chael to get close enough to score some blows and more importantly: take-downs.

~Anderson will not be on his back as much as last time but when he is, Chael will keep him there and score

~no submission TKO or KO; both guys will minimize mistakes

~3-1-1 for Chael. Chael's take-downs and control on the ground will edge out Anderson's stand-up which as I mentioned earlier will not be dominating. And, 3-1-1 sounds one sided but they will be close rounds.

~**if it does not go to decision it will be because Anderson let his emotions get the better of him and got reckless which brings it back to my first point. He would only make that mistake once and Chael would have to capitalize.

(But that doesn't seem as likely as drawn out war.)

~there will be a third fight, no matter who wins
