#2 Ryback

Another WWE superstar who was never given his full due is this man. Ryback was initially depicted as 'The Big Guy' who was hungry to be fed more. However, WWE could never fully utilize the potential of his superb talent and ability to combat inside the ring. Backstage politics also played a part in his demise as well.
Ryback won the Intercontinental Championship once and that was his only taste of any championship in WWE. His catchphrase "Feed Me More" was loved by the fans and he was recognized as a dominating force in the WWE. Inspite of that, apart from a few narratives with The Nexus and Curtis Axel, Ryback has nothing to brag about in the WWE.
Had he been in the Attitude Era he would have done much better. His strength and feuds could have been used to obtain high viewership. Fans would have loved to see Ryback vs Stone Cold or Mick Foley.
