#4 Alberto Del Rio
Alberto Del Rio has been one of WWE’s greatest finds over the past decade or so. Even though the company has had several issues with Del Rio, he was one of their most solid performers whenever he was presented with the opportunity.
Del Rio signed with WWE in 2009 and was assigned to Florida Championship Wrestling (FCW) after which he made his SmackDown debut where he defeated Rey Mysterio.

The WWE Superstar had a couple of good reigns as the WWE Champion and World Heavyweight Champion before he was released from his contract five years later in 2014 after an altercation with an employee.
Del Rio returned to the company within 18 months of his release and defeated John Cena for the United States Championship right away.
Del Rio had a much better first stint in WWE than his second one
However, his second run wasn’t as great and after forming the League of Nations and remaining with the faction for a few months, he was suspended because of Wellness Policy violations. Del Rio then went for the opt-out clause from his WWE contract as he was unhappy at how he was treated.
He was one Superstar who surely did not live up to his potential even though he won a few major titles during his two runs with the company.
