#2. Seth Rollins Executes WWE's "Heist of the Century"
Some WWE fans might disagree that this cash-in belongs in the #2 spot on this list. However, that is only because they would want it to be placed higher.
At WrestleMania 31, the build leading to Roman Reign's face-off with then WWE World Heavyweight Champion Brock Lesnar was the source of much controversy and fan disapproval. The last thing WWE fans in 2015 wanted to see in the main event was The Big Dog go over The Beast and become the new champion.
Following the break up of The Shield, WWE set in motion a plan to make Roman Reigns a main event star. From the summer of 2014 to early 2015, making Roman Reigns look strong was a top priority for WWE. This included big wins like his SummerSlam match with Randy Orton, consistent wins on TV, and of course his Royal Rumble win in January 2015.
However, as much as WWE wanted the Big Dog to become the biggest star in the company and carry the WWE World Height Championship, die-hard WWE fans were not very accepting of this. They saw right through WWE's clear push of Reigns, and quickly felt that WWE didn't care what they wanted, rather looking at what they saw as their next John Cena.
With this, fans consistently booed Reigns, and were concerned that WrestleMania 31 was going to be the place where WWE would simply anoint Reigns. Lesnar was a part-timer even then, which made fans extra nervous. Many WWE fans felt that the result of the match was nothing but a foregone conclusion - Regins was going to become World Champion whether they liked it or not.
Towards the end of the match, it seemed as though WWE was setting up for Reigns to possibly begin to mount his big comeback and win his first WWE world title. However, WWE had a plan B that no one saw coming.
As both Reigns and Lesnar lay exhausted on the ground, Seth Rollins' theme music hit and the former Shield member sprinted to the ring to insert himself into the match. Much to the delight of WWE fans in the arena.
Rollin's cash-in was the first to successfully happen during a match, as the match then became a triple threat match. Before long, Rollins would set up Reigns and hit his signature Curb Stomp finisher. This secured him the win, completing the "Heist of the Century".
To this day, many fans regard this as one of the most unexpected and exciting cash-ins in WWE history. WWE fans constantly refer to this cash-in as the signature moment when Seth Rollins proved that he was a top WWE star and could hold his own.
The timing, the execution, and the pure gravity of the moment make this cash-in a no-brainer for a Top 5 list. However, there is one Cash-In that beats it as the best cash-in in WWE history.
