The widely held belief is that Brock Lesnar would be immediately booked into a rematch against Alistair Overeem if he decides to return to UFC. Overeem was the person that defeated him for the heavyweight championship before he decided to retire from MMA and return to WWE.
There are still plans within WWE to turn Antonio Cesaro into a baby face. It was supposed to have happened already, but the creative department simply has not found the time nor a suitable story to break him away from Zeb Colter and Jack Swagger.
Daniel Bryan, Chris Jericho, Kane, Mark Henry and Randy Orton all stepped into the steel cage at Elimination Chamber 2013, but it was Jack Swagger, accompanied by Zeb Colter, who victoriously walked away from the event with a shot at the World Heavyweight Championship.
