That's interesting I thought about that too maybe....it would be funny
Another way for him not to go away for years is for the McMahons to honor their contract agreements....I'm only speculating here so don't get too angry or carried away.
Rock said on RAW that he is never going away. Now, anyone with common sense knows that he isn't back full time or even part time really. After Wrestlemaia he'll probably be gone.
Anyways, perhaps it turns out that Rocky is the RAW general manager. Every now and then instead of an email we get a video email from The Rock. Then every few months or so when something big is going down The Rock comes out live on the show.
It's probably not The Rock, but it'd be a nice way of keeping Rocky involved so he doesn't go away again for years.
