#2 The Viper is put down
The spring of 2002 saw possibly the greatest batch of WWE rookies making their way to the main roster. The class consisted of the likes of Brock Lesnar, John Cena, Batista, and Randy Orton. All four Superstars went on to become multiple-time champions. By the time SummerSlam 2016 rolled around, WWE announced that Brock Lesnar will face Randy Orton at The Biggest Party of the Summer. The match was dubbed by WWE as "fifteen years in the making".
