2. CM Punk
There is no way that a person can keep CM Punk away from a list like this. Punk gave a stellar performance last night on RAW as he leaped onto Ryback from the top of the ramp. Despite his injury concerns, Punk looks ready for his match against Ryback and with things really heating up between the two, one can expect a great physical match.
This will mostly and quite rightly be the end of the Punk-Heyman saga as I feel we have seen it all. Ryback will have to lose but WWE can make him look strong in his loss. Maybe Axel can feel jealous about Ryback and cost him the match.
As far as Punk is concerned, expect him to continue the good work that he has been delivering match after match. Despite his losses in recent PPVs, Punk has unarguably delivered the best matches of his career against Brock Lesnar and Curtis Axel.
