As it has been said a million times before: Sheamus' "downfall" has been because of Kevin Dunn. The guy just isn't a fan of his. Also, I see this as a great way of getting Sheamus into the main event again. If they just thrusted him back into the main event, to compete for WWE titles, it would seem like he doesn't deserve it, like many people said the first time he won the WWE title. But this way, he will look like he has gone through alot to finally get a WWE title match. And also, him and Bryan will have spectacular matches together, and will bring prestige to the US belt.
