#2 Dean Ambrose's 351-day US Title run
The Shield is one of the best factions to ever grace the Squared Circle. They used their unity and numbers to their advantage, taking over the main roster like no other stable ever had.
They put on great six man tag team matches over the course of their career as a team, and won the WWE Tag Team Championships at Extreme Rules 2013, from Team Hell No. On the same day, Ambrose defeated Kofi Kingston to win the United States Championship.
Much of Ambrose’s reign was forgettable, as he was involved with The Shield and their dominance on the main roster. They entered the top story-line, siding with the Authority against rebels like Cody Rhodes, Daniel Bryan and CM Punk.
Through the beginning of 2014, The Shield would initiate a slow baby-face turn, assisted by the crowd’s adoration for the Hounds of Justice. They would then proceed to put on some of their best matches against The Wyatt Family and a reunited Evolution over the first half of the year.
That’s not to say Ambrose never defended his title at pay-per-views. He defended his title on 4 occasions, winning only one of his matches by pin-fall, and retaining the championship in other matches through disqualifications and count-outs.
Following the angle with the Rhodes brothers at Battleground, Ambrose never defended his title on pay-per-view. He would then lose his championship to Sheamus on an episode of Raw, in a battle royal involving 19 other Superstars.
The entire reign was unnecessary and unproductive. The championship could’ve been given to another Superstar, since Ambrose was always putting The Shield and their missions on top priority, with the belt serving the purpose of an accessory, and nothing more. I would’ve also considered all the members of The Shield defending the US Title once they lost their Tag Team Championships to Cody and Goldust.
