#1: Must avoid: Alberto Del Rio
Seen by many as the Mexican JBL, Alberto Del Rio burst onto the scene in 2010 and was very impressive.
In his rookie year, Del Rio won the 40-Man Royal Rumble match, the RAW Money in the Bank ladder match, and the WWE Championship.

Backstage though, attitude problems between Del Rio and the WWE made for some tense moments, and after his second release in 2016, it seems the Mexican Aristocrat is gone for good.
A mixture of suspensions and a toxic relationship with Paige certainly didn't help Del Rio, especially as the company has worked closely with the Anti-Diva since her retirement, including working on her biopic Fighting with my Family.
Though the former World Champion has said he hopes to return to WWE one day, we wouldn't bet on it.
