With guys like Mark Henry and Alberto Del Rio already "moved" between brands, it would be interesting to see how they go about this years draft.
I would love to see Miz, heel or face, on Smackdown. I feel that he has been sort of lost on RAW of late, even with the Team Johnny match at WM. If he does move, I can see him as a face, due to all the media coverage he does, and that fact SD is heel heavy.
Christian to RAW could be a good move for everyone. As someone posted earlier, a Christian-Punk feud seems ready made for when Jericho leaves again.
If you forget the impending Cena-Lesnar feud, I could actually see Cena being drafted to Smackdown. All the big events will take place on RAW anyway, and it seems that the blue brand is a little short of faces in the main event scene. I mean Orton, Sheamus and Big Show, against 5 or 6 heels, just doesn't work. With the lines blurred on a brand "split", and talent appearing on both shows, Cena's major storylines could still happen on RAW, with the bulk of his time on Friday nights. RAW's ratings aren't going to drop just because Cena isn't on the RAW "brand".
I feel that one man, DOES need to move. Jack Swagger, like Miz, has been sort of lost in the WM shuffle, and a move back to Smackdown could help him. He is a gifted wrestler and the guy doesn't seem to cope awfully well in the promo-heavy RAW environment.
It could be that with the GM Johnny arc, that this year's Draft is the final one.
