#4 King Corbin
Baron Corbin has solidified himself as a top heel in WWE and spent the last few months getting the better of Roman Reigns until The Big Dog finally bested him at the Royal Rumble PPV. Now that it appears that the feud with Roman Reigns is over, he could pick a fight with the much smaller Daniel Bryan, something King Corbin seems predisposed to do.
It would be quite easy to set up a WrestleMania program with the two of them. It's likely that the number one contender for the Universal Championship will be determined inside the Elimination Chamber. Bryan could eliminate Corbin from the match, but before leaving the structure, Corbin could attack Bryan, either leaving him unable to continue or directly leading to his elimination.
Corbin could then spend weeks ducking Bryan, with The Planet's Champion taking on the likes of Dolph Ziggler and Robert Roode before finally getting a match with Corbin at WrestleMania. This could be a very intriguing match-up, and it makes sense that Bryan, who is one of the most popular wrestlers in the company, and Corbin, one of the most hated heels, would be looking across the ring at each other in Tampa on April 5th.
