Who can replace CM Punk in the WWE?

Dean Ambrose:

With Roman Reigns getting a push, Dean Ambrose can’t be far behind

Another guy that lets his presence known on the microphone is Dean Ambrose. Ambrose has a almost chilling way of enouncing each word is his promos, that you start to believe if he’s serious about what he says he’s going to do. The man gives off a dangerous look, and that might just be what the WWE needs at this time.

Ambrose is by no means ready for this position as of right now. He will still need at least a year to perfect ability in the ring as a singles competitor. but given time, and a few changes to his current move set and pace of his matches, Ambrose could certainly begin to fill that void that Punk will leave in the WWE.
