#2 The match is bound to be a disaster

Let's face it!
it has been a long time since Undertaker had a good match. At this point, he has turned into a nostalgia act who still gets better pops than the majority of the WWE roster. But is that enough? WWE was aware of this fact at last year's WrestleMania, and thus we got a very short Undertaker vs John Cena match.

Since then, The Phenom has wrestled in Saudi Arabia on several occasions, with every single bout being a disappointment. A visibly old Undertaker vs a possibly injured Sting screams nothing but a disaster at this point. What's the point of this match, if it's bound to be bad, and would end up disappointing the fans more than they would have been had the match never happened?
