#3 Braun Strowman
One of the few Wyatt Family match-ups we haven had the opportunity to see in the WWE is one between Braun Strowman and Bray Wyatt.
Strowman's time in the Wyatt Family was fairly short and he soon moved away from the group to go and make a name for himself as a singles star.
Given Wyatt's penchant for revisiting the past since he made his big return, this feud probably wouldn't be too difficult to set up. The shared history of the two men could easily be tied into a storyline and it could be interesting to see Wyatt wrestle with his conscience as The Fiend lays waste to one of his former allies. We have already seen The Fiend take out Strowman once already, so they could easily build that into the story as well.
The only potential issue the WWE might have with booking this feud is that both men are both likely to need a boost after defeats at Crown Jewel. Strowman and Wyatt have both become perennial losers when it comes to major feuds, and it might be a smarter idea to book them both into different feuds that they can record a significant victory in.
That being said, a feud between the two could still be a lot of fun if the WWE weren't too heavy handed and made Strowman look strong in defeat.
