This may sound crazy, but I think this is the worst season yet of this show. Rampage 'retired' because he cannot take the mental abuse some dish out to him.
It's too bad. Rampage is too entertaining to go out like that. He's no coach, but he's a hell of a fighter. Hope he finds his way back.
Oh, and Rashad represents himself well on the show. I'm no fan, but he clearly understands the value of coach/fighter relationships.
