WWE.comThis particular rivalry would be fresh, new and exciting. It was actually on the night of Punks departure - the Royal Rumble - where Roman Reigns thrust himself into the spotlight by being one of the final two participants and setting a record for most eliminations in a Royal Rumble match. Since then, Reigns has gone from strength to strength and is currently fully involved in the WWE World Heavyweight Championship picture. A story-line between the two could be centred on Punk wanting to regain the territory he lost during his time away, with Reigns representing a new threat that he needs to bypass. The renewed rivalry wouldnt be too unfamiliar either, with the two crossing paths in late 2013/early 2014 when Reigns was part of The Shield.
