#2 Braun Strowman

This one has already happened a few times amidst the Wyatt Family/Shield feuds and the recent Shield/Dogs of War feud. Like Elias, Braun Strowman turned to the side of the light, or maybe antihero, on the same night that Dean turned on Rollins, and by extension, Roman.
Strowman has always been a fan favorite, especially with his matches against Roman. Now that his mini-heel run is over again, he's back to being cheered for the right reason. No matter what he does he's going to have the crowd behind him.
Look who just shut down all of Tony Khan's critics! More HERE.
If Strowman is holding the Universal Title at some point, he might have a ready and willing challenger in the form of Ambrose. Ambrose will probably be a little more believable as a badass heel than a hot dog cart pushing face.
Yeah it was funny to a degree but it was hard to take Dean seriously then. We should certainly take him more seriously now. He and Braun can have all sorts of matches, so this one is a likelihood if the red belt changes hand next year.
