#3 Dolph Ziggler
Dolph Ziggler's recent heel turn has given him a renewed focus, and one of the few accolades he doesn't have on his resume is a Royal Rumble victory. He isn't being talked about as one of the favourites to win, which is exactly why he would be a good choice.
The Showoff is always capable of stealing the show with opponents who are on his level and he is popular enough with the fans to justify giving him one of the main event spots at WrestleMania 33. He's been there before, so he wouldn't crack under the pressure.
If AJ Styles were to retain the WWE Championship against John Cena, The Phenomenal One and Ziggler would be able to tear the house down together. It doesn't even matter that both men are heels because the crowd usually cheers for them anyway.
Ziggler is one of the most reliable performers on the roster, and it's a shame that WWE hasn't given him a more prominent position over the years. If there was ever a time to give him another shot at being a main event player, it's at the Rumble.
