Notable exceptions
There are so many WWE superstars who do belong in the Wyatt Family. But somehow, they're at a stage of their career where a Wyatt Family stint may not necessarily benefit them.
The three names that immediately come to mind are Randy Orton, Braun Strowman and of course, Daniel Bryan. Each of these men has been in the Wyatt Family in the past, but unfortunately, they're so well established as singles stars at this time, that I see no point in having them join the Wyatt Family once again.
The same could be said for someone like Lars Sullivan, whose physical attributes make it seem like he would be ideal for the Wyatt Family. He's doing fine in a singles environment for now.
Rowan is also doing fantastically as Daniel Bryan's sidekick. Eric Young could become a potential member, but he'd be number 7 in my list of probable candidates.
