Dean Ambrose, Seth Rollins and Roman Reigns all are undefeated at WrestleMania, a record that is unlikely to remain intact for all three after Sunday. The trio represent the future of WWE, and they got their careers off to a great start with their 2012 debut. Their first WrestleMania, at XXIX in 2013, was a great sign for the group, as they defeated three former world champions: Sheamus, Randy Orton and the Big Show. Last year, they toppled the New Age Outlaws and Kane in under three minutes. Sure, they havent been around long, but undefeated wrestlers at WrestleMania are rare (especially among active performers), so they deserve kudos.
