5 reasons why Undertaker should quit wrestling for good, and 5 reasons why he shouldn't retire just yet

#3 Should NOT retire: The WWE still needs him

John Cena is a polarizing figure who never truly united the WWE Universe behind him, and has moved on to more of a movie actor career. Roman Reigns is also polarizing, and despite WWE's best efforts, they cannot make him into another Hulk Hogan or even John Cena.

In short, the WWE needs Undertaker's presence. They benefit from just the SUGGESTION that he might perform (ala Cena's repeated attempts to draw him out prior to WrestleMania 34) Undertaker equals money, and there's nothing wrong with him sticking around a little longer even as a part-time talent.
