I don't really believe in the notion of a "WWE reject" these days.
From what we hear through dirt sheets, over the last 5-10 years your fate in WWE has been decided by one ancient guy who isn't current with pop culture or young fans. These guys, for the most part, weren't rejected by fans or by writers, they were rejected by VKM. Certainly that's the case with Brody Lee and the Revival.
Along with the current people in there as well. Like Zayn, Balor, Cesaro, Alexander and Ricochet. So much talent being under-utilised.
