The Undertaker has worked more WWE matches in 2015 than he did from 2012 through 2014 combined. He's obviously not getting any younger so many fans believe the reason for the increase in his WWE appearances this year has to do with his career coming to a close. Perhaps this year, starting with WrestleMania 31, was to be a farewell tour of sorts for The Deadman. After an extremely controversial victory over Lesnar (but a victory nonetheless), teaming up with his brother Kane at the same event he debuted at 25 years prior, and another performance inside a match he helped create at Hell In A Cell, why not add the Royal Rumble Match to The Undertaker's potential bucket list of things to do one more time? Would anyone complain if the main event of WrestleMania 32 was Roman Reigns vs. The Undertaker for the WWE Championship? The Undertaker entering and winning the 2016 Royal Rumble could be the beginning of the end for the Deadman in Dallas and if so, there's far worse ways for him to go out.
