A former four-time world champion, a former Royal Rumble winner is now a lower mid card. You cannot blame Sheamus for this demotion, it is the fault of the creative teams who continuously booked him poorly. So what are the best booking options for the Celtic warrior? Let us discuss;

Continuing as a tag team with Cesaro, split later – To be honest, whatever he is doing right now with Cesaro as a tag team is not bad. It’s just not the right way of booking. They should win the tag team titles again and they needed to be shown as pretty strong individually, because they will split up sooner or later, so this tag team must not affect their singles’ career in future.
Forming a stable like the League of Nations – The League of Nations was a great idea, just terribly booked. Big heel stables are always interesting to see. For example, nWo was one of the main reasons behind WCW’s rise, D-Generation X was the answer of WWE for WCW’s nWo. Right now WWE does not have any interesting stable. You can see Sanity is doing an excellent job at NXT, so why not forming one in the main roster with Sheamus as the leader?
Gimmick change – Sheamus has been playing the same gimmick since the very first day of his debut. It is a high time to change his gimmick. Fans are not enjoying his current gimmick much, which is affecting his career. He is a great athlete and such things being barriers before his rise is not a good thing to see.
Turning him a proper heel – Tell me, is Sheamus a heel right now? Or is he a babyface? What is he? Neutral? This is the biggest confusion, we do not know what is his current situation. Keeping his current gimmick in mind, a heel persona suits him more. So they should turn him a proper heel.
Sending him to Smackdown – Another reason why he is suffering from poor booking is because of his brand, the problem that most of the Raw wrestlers are facing right now. The raw creative team is not being able to utilise everyone perfectly like Smackdown is doing. So if he goes to Smackdown, he will get proper booking and he might get his lost glory times back as well because Smackdown creative team know how to book which athlete properly.
