5. The Undertaker vs. Brock Lesnar - WrestleMania 30
There's a general consensus amongst wrestling fans (or at least there was before Sting signed with WWE) that The Undertaker's defeat at WrestleMania 30 was the end of the road. The way he walked off at the end of the contest and trudged to the back was a real sign that he wouldn't be wrestling again. But if you look closer, there's an even bigger sign that Taker should call it a day after his match against Brock Lesnar - the actual match itself. Taker has been getting slower and slower inside the ring for the last few years - which is probably expected given how he only competes once a year. We can all forgive him for that, as he's provided wrestling fans with some absolutely outstanding moments that will stand the test of time. But he was miles behind Lesnar - another part-time guy who has been lamented himself for being sluggish in the ring - all the way through the match, and he actually looked hurt at the end of the contest. He ended up in hospital after the match, which perhaps told Taker and Vince McMahon all they needed to know about his future. The match itself was poor, and it never got going due to Taker's poor physical shape. At least the WWE didn't go with it as the main event, and they let Daniel Bryan have his moment.
