#3 Lack of Royal Rumble success
When we look at the careers of some the greats of this industry then there is one thing common, and that is the accomplishment of winning a Royal Rumble. The Royal Rumble holds a special place in the WWE folklore and ardent followers of this gigantic company have showered their love and support for this unique matchup.
Fans have enjoyed the Rumble ever since its inception, and it is a reason why the company gives such level of emphasis to this competition. When it comes to The Shield, Seth and Roman have each won the Royal Rumble once in their career, which then earned them a chance to face the world champion at WrestleMania.
Winning a Royal Rumble is a special thing simply because not many men can claim to have outlasted 29 other opponents in order to be the one! Dean will surely reckon this as something he should've done before leaving the company simply because both his Shield brothers have done it, thus giving them an edge.
