Kevin Nash will be at RAW this Monday and he is expected to be a regular character going forward. He will be doing a program with CM Punk which will culminate in the two meeting in the ring at some point. This is supposed to give Punk a major name to work with that would put him over.
Nash didn’t get a very big reaction coming out on RAW, and the general feeling backstage is that WWE needed to do a better job explaining to the current generation of fans who he was. This was originally not a concern because of the much bigger reaction Nash got at the Royal Rumble, which likely had more long-time fans in attendance. WWE may produce a video package highlighting Nash’s career and controversies.
A couple backstage sources also felt that Nash’s jabs at Punk on RAW contained too many “inside” references, and Punk got the better of him. This may have been on purpose though, as Punk is the babyface.
