Although the Undertaker has become more synonymous with WrestleMania than Shawn Michaels, Undertaker debuted at the 1990 Survivor Series. As such, it would make sense for him to say his final goodbyes to the wrestling industry at the same PPV as the one where the Undertaker was born. It would be a symbolic way to go out, at the same show where his career began. Although doing so would certainly take business away from WrestleMania season, it would help WWE during the fall season, when WWEs numbers usually go down due to increased competition from other sports and entertainment programs. Having Undertaker appear at the November Pay-Per-View would certainly help boost ratings or gain more WWE Network subscribers. It would also make Survivor Series feel big again, especially since it has become the least significant of the Big 4 PPVs in recent years.
