#4 Sheamus

Sheamus shocked the WWE Universe when he defeated John Cena to become the first ever Irish-born WWE Champion in 2009, and that too in less than 6 months of his WWE arrival. Sheamus' career witnessed a slight downfall in late 2010 and he transformed into an upper mid-card jobber but he again started to pick momentum with his face turn in 2011. Sheamus went to on the win the 2012 Royal Rumble match and chose to face the World Heavyweight Champion Daniel Bryan at WrestleMania. Sheamus was about to witness the best year of his wrestling career but unfortunately, his match with Daniel Bryan took place in the opener and ended in just 11 seconds and was billed as "Worst match of the night".
It's understandable that The Rock vs. John Cena was much bigger in stature than Sheamus vs. Daniel Bryan but it should have been given the chance as Daniel Bryan had always been popular with the fans while Sheamus was improving as a babyface too, more or less similar to Batista during WrestleMania 21 season. Sheamus didn't main event WrestleMania but what's even worse was that he wasn't even allowed to showcase his potential and have a good match at the Grandest Stage of Them All. Sheamus and Daniel Bryan had an amazingly intense 2-out-of-3 falls match at Extreme Rules the following month.
