The vast majority of the men who won the Royal Rumble have something in common - they all came up unsuccessful in other Royal Rumble matches. Three of the winners, though, only competed in the Rumbles they won, and therefore, their records are still unblemished - 1989 winner Big John Studd, 1999 winner Vince McMahon, and 2003 winner Brock Lesnar. Studd passed away in 1995, while McMahon is unlikely to enter another Royal Rumble. Brock Lesnar, though, has the opportunity this year to increase his 1-0 record to 2-0. As impressive as perfection already is, a second Rumble win with no losses would be unprecedented.
