7. WrestleMania 21 - Undertaker vs. Randy Orton - This match may be the only instance where we actually though that The Undertaker's Wrestlemania streak was going to come to an end. We admit, we weren't looking forward to seeing Orton's bland offense against Taker's expansive arsenal. The match itself is a surprise unto itself. Orton had something to prove that night and The Undertaker came ready to steal the show (as usual). This slept-on Undertaker match was surprisingly fun and filled with hype. That RKO out of a chokeslam moment is worth the re-watch alone.
