The Undertaker's WWE contract is reportedly expiring soon, casting a little doubt over a potential WrestleMania 32 showdown with Sting (as well as a host of other rumoured names). Fans of the Deadman can rest easy however; the chances of 'Taker turning down a marquee bout in his home state of Texas are slim, given the eagerness with which he has returned to the past few WrestleManias despite a very limited schedule. Is this the right decision, however? Even though the Undertaker would likely continue to dart in and out of the WWE, spending most of his time training his ageing body off-screen, is it not time for the Phenom to hang up his boots once and for all? The Undertaker is undoubtedly one of the most legendary and beloved stars in wrestling history, one of the last defenders of kayfabe, and one of a few WWE performers regularly recognised and referenced in mainstream pop culture. His retirement would be a huge loss to the business, but also makes sense for a number of reasons. Here are seven arguments for the Undertaker's retirement. A contract extension may seem tempting, especially if it's limited to one final 'Mania showdown, but the Deadman's wisest decision may instead be to simply walk away.
