4) His Creative Ideas
A lot of Punk’s frustration came from the booking of his character and lack of firm direction. In 2013, Punk was floating around from feud to feud. As IC Champion, he would have had several new young talents to work with and develop new feuds.
Punk would have been the gatekeeper, or filter for the next line of guys to gain experience against “The Best in the World” and learn from him. Punk’s title reign would have been just as much about his opponents as him. That’s what has made John Cena’s US Title reign so valuable in 2015. Punk would have done that in 2013.
