#4 and #3 Enzo Amore and Big Cass
The Certified G Superstar Enzo Amore, who started wrestling in 2012, retired last year. Enzo is a wrestler that wasn’t popular for wrestling but his amazing promos. I would say that he was just an average performer with a golden voice.
His tag team with Big Cass (now Big Cazz) became popular among the WWE Universe, but since they parted ways, things have changed significantly. In 2017, Cass sustained a knee injury which kept him out of actions for months.
Now coming to the point, Amore and Cass are no longer WWE Superstars. They both got fired by the company for different reasons. Amore got accused of sexually assaulting a woman -- which immediately led to his release. On the other hand, Vince released Cass because of his unacceptable behavior towards WWE Officials and breaking the script. Not only these two firings were justifiable but also are a strong reason why these wrestlers won’t appear in WWE again.
