#1. The Undertaker
I know what you're thinking - The Undertaker? Why The Undertaker?
We know that The Dead Man is making his return to the ring at Extreme Rules this year, and he will be teaming with his WrestleMania opponent Roman Reigns to face the team of Drew McIntyre and Shane McMahon.
If reports suggesting The Phenom's TV return is to help boost declining WWE ratings, then it seems reasonable to assume Undertaker will be around for the next few months, and might even be appearing on TV regularly from now until WrestleMania 36.
Should The Dead Man indeed be returning to WWE TV on a semi-regular basis, why not turn him heel? It's a version of The Dead Man we haven't seen in years, and it could culminate in one final match at WrestleMania against the man who holds a coveted win over 'Taker at the big PPV - Roman Reigns.
One final match for The Undertaker at WrestleMania, inside Hell in a Cell, against The Big Dog Roman Reigns, could be the perfect sendoff for The Dead Man, and a return to Big Evil for 'Taker could be just what WWE needs to infuse a bit more edge into its transformative game plan.
Who else in WWE do you think needs to turn heel right now? Let us know in the comment section!
