I believe Rivera will wrestlebox his way to a decision or late T/KO.
I think he'll get his jab going, pick away a bit at that lead leg, and keep Almeida honest with well timed TDs. Almeida is a fun striker but his defense is limited and his stance often leaves him open to double legs.
Either way it should be a pretty fun fight. Imo Rivera already has done enough for at least a title eliminator. Unfortunately, the way things are now Cruz is above him in the pecking order and the Dillashaw/Garbrandt fight is still trying to be made. He might have to fight again even if he wins tonight before getting a shot.
