The cheapest, yet best heat would be for Zeb Colter to announce that he'd convinced WWE that Alberto Del Rio's matches should only be called by Spanish speaking announcers Carlos Cabrera and Marcelo Rodriguez. All it takes is for John Cena to put Del Rio through one Spanish announce table for Colter to have the premise by which this could happen. Zeb gets angry, shows a video package of years of Spanish announce tables being destroyed, and it's simple from there. In order to revive their product in general, WWE needs to strongly consider building excellence from within. Thus, in a manner similar to mining excellence from the New Day, WWE could take two pieces of their roster who likely have never been called upon to be heat seekers could actually make a huge difference.
