#1.) Seth Rollins – 2015
This was always going to be on top of the list. Seth Rollins’ MITB cash in at WrestleMania, known as The Heist of the Century is without a doubt the greatest cash-in in WWE history. The circumstances made it all the better. Fans didn’t want to see Roman Reigns become WWE Champion and they were tired of seeing Brock Lesnar as a part-time champion.
Seth Rollins, despite being a heel, was quickly winning over the WWE Universe and in the main event of WrestleMania 31, he cashed in the MITB briefcase to become WWE World Heavyweight Champion, a title he would hold for six months and never actually lose in that run.
