#3 Alex Riley (2011)
Alex Riley made his first on-screen appearances for WWE as a rookie on the second season of NXT. Paired with The Miz as his professional mentor on the show, Riley finished the competition in third place. The A-Lister's protege also had a shot at the Money In The Bank briefcase.
Following the conclusion of the competition, Alex Riley began to appear on RAW as The Miz's protege, often interfering in matches on his behalf. Riley enjoyed significant exposure in his heel role, especially when The Miz cashed in the Money In The Bank briefcase on Randy Orton to become WWE champion in November 2010.
The partnership even led Alex Riley to an appearance as part of the WrestleMania 27 main event. Riley accompanied The Miz to the ring for his championship defense against John Cena. Riley interfered several times on The Miz's behalf, in a match that also famously saw involvement from The Rock.
Alex Riley turned babyface after The Miz blamed him for losing his WWE title to Cena the following month, but was rarely featured prominently following the pair's feud.
Alex Riley competed in his sole Money In The Bank match in 2011, featuring in the RAW brand match won by Alberto Del Rio. By the end of the year, Riley was mainly competing on Superstars.
Several runs in NXT, and a stint as a television announcer, followed over the next few years. Truthfully, though, Riley never came close to recapturing the form which saw him compete for the famed briefcase. He was released from his WWE contract in 2016 and moved into acting. Alex Riley did, however, hint at a comeback late last year.
