#3 Baron Corbin - 11/2
In a somewhat strange turn of events, Baron Corbin is one of the favorites to win the Greatest Royal Rumble. He certainly has a pedigree with winning these kinds of battle royal matches dating back to his win at WrestleMania 32, but he doesn't really have all too much momentum even after being moved over to Monday Night Raw in the Superstar Shake-Up.
There's still a great deal of potential in this guy even if some fans don't want to admit it, so maybe, just maybe, this could work out for the best for Corbin. His imposing style allows for him to make a notable impact in Rumble matches, in a similar manner to Kane. If he can tally up a good amount of eliminations, people may start to view him a little bit differently.
