To the post above, I think that you are wrong about HHH being the star. It appears Edge and John Cena are the biggest stars in the company. (With Rey Mysterio behind, which is why it annoys me that he is buried)
Triple H is losing steam and I think this rivalry is just what he needs to gain it back. On smackdown he has been lost in the shuffle with Undertaker being face and Edge/Hardys being the main storyline. Moving him to Raw will benefit everyone.
Just to clearify there for you, I wasn't refering to Triple H. being the "biggest star" in the W.W.E. I was refering to John Cena, being on the flagship show (Raw) and being possibly threatened to moving him to the second rate show, Smackdown, that isn't even carried by all network providers.
In other words, I felt it would hurt the company to move Triple H. back to Raw so quickly after he just moved to Smackdown, only to then move your top talent in John Cena, off your top show in Raw.
As far as the Triple H./Randy Orton rivalry, you're correct, it is just what he needs to regain some lost steam.. but he's Triple H., regardless of how "lost" you think he may have become on Smackdown, he was never lost enough to the point of being invisible.
Moving Triple H. to Raw, in my opinion, however, will NOT benefit everyone. It'll benefit Triple H., in getting him back into the Main spotlight of the signature show. And likely in the Main Event, at WrestleMania 25, which in all right, should go to Shawn Michaels and the Undertaker.. if that happens.
But all of that, would be arguments for other threads. To stay on topic with this one..
John Cena chasing Edge to Smackdown, is a bad idea. Mainly because the Cena/Edge feuds from 2006 are still fresh in a lot of people's heads and they don't want much more of it. So once Cena "wins", assuming he would, what then? Feuds with Matt or Jeff Hardy? The only logic would be a feud with the Undertaker.
Or a stupid draft move that would resend Cena back to Raw, and Triple H. back to Smackdown, after their "Mania" storylines were complete.
EDIT: I firmly stand by my prediction that all four individuals, John Cena, Edge, Triple H. and Randy Orton will alternate shows, leading up to WrestleMania. They'll all four bounce back and forth between Smackdown and Raw. To boost ratings through the roof, as much as possible. Then, after Mania, they'll all likely return to their respective brands.
