#1. Luke Harper
Luke Harper has been vocal about his frustrations in WWE dating all the way back. Around pre-WrestleMania period, he admitted that he was cleared to wrestle in February and stated his frustrations of not being utilized.
He then appeared at the Andre the Giant Memorial Battle Royal and hasn't been doing much since, despite being clear. Harper made a big mistake when he stated on social media that he requested his release from WWE - because his request got rejected.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
Moreover, it was worsened by the fact that WWE froze his contract when injured and added the months to his contract. As a result, his WWE contract ends around November 2019.
It's absolutely no secret that Harper is biding his time until it ends. He's a true wrestler and loves to wrestle in front of audiences. Being denied the opportunity probably feels like being trapped in a jail.
