6. The Undertaker Is Impossible To Replace, So When Trying To Replace Him, Maybe He Shouldn't Physically Be In WWE Anymore
Yes, absence makes the heart grow fonder, but absence also just means that the person isn't around anymore. Insofar as WWE moving on PAST The Undertaker, well, actually having him not physically present is incredibly important. If you're say, tall, brooding and physically impressive NXT performer Baron Corbin, not having The Undertaker around for wrestling fans to possibly compare you to is important. In all future big men in WWE needing to craft unique legacies, not having The Undertaker around actually makes that much easier of a proposition.
