Yep, we have absolutely no arguments with the list - especially when it comes to number one.

'Shocking' and 'stunning' are just two other words to describe Rollins' Money in the Bank cash-in at WrestleMania 31. 

After Roman Reigns and Brock Lesnar had gone the distance, Seth came charging down the ramp with his briefcase to cash-in his title shot - and boy - he didn't disappoint. 

Rollins pulled off 'the heist of the century' at WrestleMania

Catching his former Shield Brother Reigns with a Curb Stomp, Rollins picked up the three count and left Levi's Stadium with the WWE World Heavyweight Championship.

It really was 'the heist of the century' and while it goes down as the most controversial moment in WrestleMania history, it's also one of the greatest.
