Andre the Giant Memorial 30-man Battle Royal
In what is essentially a way to get several members of the roster with nothing else to do on the show, the 30-man battle royal in honor of the Eighth Wonder of the World doesn't really have a participant who could greatly benefit from winning, unless that participant has yet to be announced. Of the announced participants, my top five favorites are: Big Show, Sheamus, Big E, Dolph Ziggler and The Miz.
Show has never really gotten his WrestleMania moment, and because of comparisons to Andre in the past, that's a reason to give him a win. However, I think his role will be more suited to help put over the eventual winner.
Sheamus is a perennial favorite of WWE management and would be a fine choice as well, although if he does win, I think this match should be a vehicle for a heel turn, as he's done about as much as he can as a babyface.
Big E is already the IC champion, but if he's being positioned to move up the card, a win here would go a long way. Instead, I suspect his budding feud with Alberto Del Rio will be furthered here.
Dolph Ziggler? He's a dark horse, but WWE seems to be getting behind him again and he'll be an important part of the upper mid-card post WrestleMania when the part-timers are gone.
Not announced yet, but possibly the odds-on-favorite is Alexander Rusev. He's been getting a lot of TV time for not wrestling any matches yet (sans a short appearance in the Royal Rumble) and if he's going to get a mega-push out of the gate, this is how you start it.
However, my pick to keep his WrestleMania undefeated streak alive is The Miz (kind of -- he and John Morrison lost in a pre-show match back at WrestleMania 25). After months of being an ambiguous tweener, Miz seems to have gone full heel lately, and has a string of losses heading into WrestleMania. A victory here could set him up as a potential title contender for a long-time rival in the coming months.
WINNER: The Miz
