8. His Financial Worth To WWE
It isn't just The Undertaker who will make a ton of money from sticking around, though, and WWE will of course make huge sums from his continued presence should he stick around beyond 'Mania 32. If they can do what they did in 2015, have him wrestle on four specials next year, then the financial benefit to the company is considerable. He's one of the biggest draws in the business and will help to pull in more subscriptions for the WWE Network. As testament to that, in terms of traditional PPV buys, Hell In A Cell (headlined by Undertaker/Lesnar) was WWE's most purchased B show pay-per-view in 2015. 'Taker is a draw, it's as simple as that. For that reason, WWE should actively encourage Mark Calaway to hang on for one more year. He's talked in the past about feeling "obliged" to help Vince McMahon, so there's every chance he'll stay if asked.
