#4 Enzo and Cass Reunion
Enzo Amore and Colin Cassady were "the realest guys in the room" when they came together in NXT. They were the hottest act down in the developmental territory and were destined for greater heights on the main roster based on their popularity.
Even though they were quite popular, they failed to win the tag championships, both on NXT and the main roster. WWE never really capitalized on the duo, apart from the merchandise sales.
They should have become the tag champions when the time was right but WWE kept on putting the title on nostalgia acts like the Hardy Boyz or the stale New Day.
Soon, Enzo and Big Cass split and this started their downfall with both of them now released from the company for different reasons.
Though, not technically sound, Enzo and Cass reunion on the AEW could bring some much-needed spotlight and star power to their tag division.
