10 Things The Undertaker Must Do Before He Retires

4. Confront Sting

There's quite a few fans out there who still want to see The Undertaker vs. Sting at WrestleMania 32, and admittedly, I'm one of those fans. While I'm well-aware the match will likely never come to fruition, there's no reason why they can't at least cross paths before they retire from the ring. With Undertaker active and Sting signed to WWE, officials would be leaving money on the table by not having them come in contact at some point. Granted, it's all dependent on Sting's health come WrestleMania season, but even a quick run-in backstage between the two icons would suffice. Picture this: Undertaker is shown preparing for his final match at WrestleMania when he's confronted by Sting in a dark corridor at AT&T Stadium. No words would need to be spoken, only looks would be exchanged between the two most mysterious men in wrestling history. Cue the goosebumps.
