Re: Why on earth are they insisting on going with the whole Cena AJ crap?
It serves multiple purposes.
1. It keeps Cena out of the WWE title picture. He can be a main eventer without tangling with Punk.
2. It fuels the Ziggler/Cena feud.
3. It keeps the most over diva on the roster with significant TV time.
4. It allows Ziggler to get the most mic time he's ever had. It allows them to see what he's capable of before giving him his title reign.
5. It gives a long term storyline for the RAW to be anchored around.
Good or bad, depending on how you look at the actual execution, the idea around it serves a great many of purposes.
