4: Big Cass
We've all watched enough Royal Rumbles to know the commentary cliches about big men in battle royal matches. The company loves to play up the idea of no-one being able to eliminate anybody over the height of 7 foot, and while those big men rarely find success in the actual Rumble match itself, given that this match is in honour of the company's most iconic big man, there is every chance someone like Big Cass could walk away victorious in New Orleans.
Cass has not been seen on TV since August when he was injured in a match on Raw against Enzo Amore. If recent reports are to be believed, however, Cass' in-ring return may just coincide with Wrestlemania.
Cass' solo career got off to a somewhat mediocre start, with his feud with Enzo Amore being one of the worst things on television last summer, and his return from injury will provide a chance for the WWE to reboot his solo run.
