Most picking Chael. He's the underdog according the betting lines though.
It's going to end in one of two ways. Silva is going to KO him within 2 or it's going to be exactly like the last fight only Chael doesn't get submitted.
I'm taking the American Gangster in this one. The same gameplan should work perfectly and he's been working on his sub defense. I think he can improve his submission more in the 2 years than Silva could become a better wrestler. Plus Chael has been fighting strikers in Stann and Bisping in his last two fights and was able to work practically the same gameplan that he'll use against Silva. Where Silva has fought Vitor (a striker) and Okami (different type of wrestler) in his last two fights. Chael has been able to tighten up his game for 2 years where Silva has had to work different types of gameplans for the last 2 years. As long as Sonnen doesn't get touched, he should be golden in this. That's my theory.
