While we still do not have a definite answer as to how long he has been upset with the company, we do know now that CM Punk was already contemplating a departure from WWE as early as Royal Rumble 2014. He vented to Mick Foley at the time about not being happy within the company and having trouble dealing with injuries.
The expectation was that ratings for Monday Night Raw would rise this week because fans would tune in to see if CM Punk would make his return or not. However, the opposite took place. WWE saw a 12 percent drop in viewership, which has to be a bit alarming since it is the time period between the Royal Rumble and Wrestlemania 30.
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.
