#4 The Big Show
There's a reason why this pick makes sense and I'll explain that very reasoning. First of all, this is probably the most unattractive pick of the list, primarily because Show doesn't really have a massive following.
However, if Harper does leave, as we expect he might, that opens up a need for an intimidating presence within the ranks of The Wyatt Family and who on the roster could possibly carry themselves with as much muscle and brute power as Big Show?
It's no secret that the Big Show is in his final years as a professional wrestler. His giant body has taken a beating over the course of his 20-year career. With that in mind, a role as the man behind Bray would give him an opportunity to remain on the roster, while keeping his actual physical activity to a minimum.
Personally, I can't think of a better way for Big Show to conclude his great career.
