#2 The Undertaker
There is perhaps no greater honour for an active professional wrestler than getting to compete against The Undertaker at WrestleMania.
Not only did Roman Reigns get that opportunity, but he became one of just two men to beat him on the "Grandest Stage Of Them All". Plus at this point, it seems like it may have been The Deadman's last ever match. What if it isn't though?
There has been no formal announcement that The Undertaker has retired from pro wrestling, and rumours of his return are not done quite yet. The Phenom could return during next year's WrestleMania season to seek revenge on Roman, only to find common ground with "The Big Dog" and team up with him to take on all comers.
It would be pretty special and would also mean less work to do for a returning Taker.
