4 Phases of Dean Ambrose's WWE career

#2 Feud with Seth Rollins (2014-15; June-July 2016)

The best rivalry of Ambrose's career

Ambrose couldn't move on from Rollins' betrayal and thus decided to take revenge. This started a long rivalry between the two, which produced some of the best and most memorable matches of Ambrose's WWE career. Rollins was hiding behind Kane and The Authority for the most part of it to stop Ambrose from attacking him.

The two finally faced off in a classic encounter at Hell in a Cell 2014 which resulted in Rollins winning after an assist from Bray Wyatt. After taking care of Bray, Ambrose again turned his attention on Rollins after WrestleMania 31, but this time, the stakes were much higher as it also involved the WWE Championship.

Seth Rollins retained his WWE Championship in the fatal four match way against Ambrose, Roman and Randy Orton at Payback 2015 and then again at Extremes Rules by disqualification. The duo against clashed at Money in the Bank, where after a classic half-hour encounter, both ended up grabbing the title and falling to the mat at the same time, with Rollins hanging on, just barely edging out his former Shield-brother.

Dean finally got to lay his hand on the company's top prize a year later at Money in the Bank 2016, when he defeated Seth Rollins after cashing his Money in the Bank contract on the same night that he won it and started his run as the WWE Champion. He retained his championship against Rollins on Raw and then again at Battleground 2016 to end their feud.
