COO: Triple H
I think he's done a much better job in the role than people give him credit for. It's also a great use for him now that his wrestling career is winding down. We all know he's going to be involved in the company for probably his whole life, so we might as well give him a role on screen that fits him and doesn't hold other talent down too much. (I know he's the focus now, but I expect him to settle into a McMahon role in a few years when he's not there every week.)
Raw GM: Stephanie McMahon
So McMahon-Helmsley can rule once again. She's a hell of a personality and she's been sorely missed for a few years now.
SmackDown GM: Theodore Long
Nothing wrong with this as far as I'm concerned. He gets the job done and doesn't make the show about him. Hard to really hate on an authority figure like that.
WWE Champion: John Cena
Because, despite his twelve reigns, he hasn't had a proper one in years. As champion, he elevates everyone around him and gives the title credibility. But it's not easy for him to do that when he's winning and losing it every five seconds.
World Heavyweight Champion: Christian
It's completely ridiculous that he was never given a proper reign in favor of this annoying Henry push. Christian is more talented in every possible way, but he's small, so he's less of a focus. I love Vince McMahon, but if I had to pick one thing I don't like at all about him, it's his attitude that smaller guys can't be champion for a long period of time. Remember that while Rey Mysterio has been champion three times, all three reigns were very short (no pun intended

).
Intercontinental Champion: Cody Rhodes
Hard to pick a better candidate for this one given how he's focused on restoring prestige to the championship. Not necessarily my favorite midcarder on SmackDown, but probably the one that can do the most for the title.
United States Champion: Zack Ryder
Because he'll take care of it while he spikes his hair. Woo Woo Woo, you know it.
Tag Team Champions: Kane and Big Show
They never should have lost the titles when they did. I love them as a team, and when Kane returns, I would love for them to get the belts back and go on a long, dominating reign.
Divas Champion: Bella Twins
Because they're hot. Beth might be better, but I have a hard time actually getting into divas matches nowadays, except when the Bellas wear those catsuits.
