As has been well-documented in the MMA community, Chael Sonnen is the only fighter who has given UFC middleweight champion any problems a midst his 15 fight win streak in the UFC.
Sonnen's boxing, takedowns and ground and pound convincingly won him four rounds on the judges score cards before getting submitted in the fifth and final round with a triangle choke.
After a dominant performance against Brian Stann at UFC 136, it seems to be a forgone conclusion that Silva-Sonnen II will happen in early 2012.
There were a couple of questions surrounding the first fight, such as how healthy was Anderson Silva coming in?
Was Chael Sonnen illegally using performance enhancing drugs, or was the matter simply an issue of disclosure?
Despite these issues, here are a few reasons why Sonnen will get his revenge and finally make good on all of his trash talk the second time around.
