#3 Seth Rollins (WrestleMania 31)
While the main event for WrestleMania 34 hasn't been confirmed, it's highly likely that it will be a rematch of Brock Lesnar versus Roman Reigns. A main event we've seen before as the two behemoths did battle at the close of WrestleMania 31.
We never found out who was the better man though. Just as the match started to enter its closing stages Seth Rollins interrupted and cashed in his Money In The Bank contract, meaning that he was added to the bout.
The Architect ultimately ended up winning what became a triple threat, and at the time Rollins was a fully fledged heel. Less than a year removed from his infamous betrayal of The Shield he managed to screw Reigns over for a second time on The Grandest Stage Of Them All.
