I'm not a fan of backing Linhares here, he's lost in the first round to any semi decent competition hes faced and Palhares is really good and durable too, even hendo couldn't stop him.
Diego is one of the best 155'ers but BJ is too good for him imo, Diego is way too sloppy on the feet and I think BJ will pick him apart...if you saw the open workout and countdown vids BJ looked awesome in them. But I think Diego has a better shot than anyone else and wouldn't be gobsmacked if he did win.
Kongo vs. Mir is a tough one too, Kongo is always improving but Mir has put on an insane amount of muscle and is really driven to get another fight with Brock, could go either way.

Good night of fights. Looking forward to seeing more of Mir.
EDIT - More of Mir 2.0
