Before walking out on the company in January, CM Punk was one of the biggest stars in WWE. He was completely over with the fans, was amazing on the microphone, and could put on a great match on almost any given night.
So, what do you think he would have been doing at Wrestlemania this year had he not walked out? It seems like every other feud with the top guys fell into place pretty well, so what would he likely have done?
