Enzo and Cass
Enzo Amore and Big Cass were a big prospect in NXT and they got over on the main roster immediately. They had the whole WWE Universe chanting along with their catchphrase every night but WWE saw fit to break them up.
Enzo was moved to 205 Live while Cass was pushed as a singles star. Enzo was fired after RAW's 25 Anniversary after WWE found out that police were investigating allegations against him and he never informed WWE about it. Big Cass was released in June.
Enzo and Cass recently reunited and made their Ring of Honor debut after crashing the ROH G1 Supercard in Madison Square Garden.
Neville
Neville left the WWE in 2018 after refusing to job for Enzo Amore and then walking out of WWE and letting his contract run out. Pac has since wrestled in Dragon Gate and signed with All Elite Wrestling earlier this year.
