10 Biggest Swerves WWE Made Before WrestleMania

10. The Big Show Debuts Amidst Cage Match Chaos (1999)

The fact a villainous Mr. McMahon character won the 1999 Royal Rumble match is something of a swerve to begin with. Steve Austin was chasing a third consecutive Rumble win in '99, only to be foiled by his arch nemesis. The box office appeal of Austin vs. McMahon continued the next month at the St. Valentine's Day Massacre pay-per-view.

Locked inside a steel cage with one another, the warring duo were set to determine whether or not Austin would go on to WrestleMania XV and receive a shot at the WWF Title. As if that wasn't dramatic enough, the cage bout witnessed the company debut of The Big Show.

Show would aid Austin unintentionally by hurling him against the cage wall. Breaking the structure, Stone Cold tumbled to the floor and was declared the winner as McMahon stood aghast inside the ring.

Many had been expecting Austin to defeat McMahon, although there were few accounting for the idea of Big Show accidentally helping his cause. The swerve here is that McMahon's Rumble victory meant little in the end, as the WWF eventually promoted Austin vs. The Rock come 'Mania anyway.
