#4 The Undertaker costs Roman Reigns the match
The Undertaker has only lost twice at WrestleMania. When he was pinned by Brock Lesnar, The Undertaker made him pay over the months that followed. The two men had a lengthy program stemming from The Phenom's embarrassing loss. Why would he go easy on Reigns?
If anything, we expect The Undertaker's appearance at RAW 25 to be much more than a visit to say hello to the WWE Universe. The Undertaker's whole agenda may be to cost Reigns his Championship. If so, we could be in for a big rematch at WrestleMania 34.
In helping Roman Reigns, The Undertaker may inadvertently assist The Miz in picking up a big win as well. The A-Lister could become an Eight Time WWE Intercontinental Champion in this very process.
Bruce Prichard recently claimed that The Undertaker is looking better than ever, and if he's in ring shape, he may not be done in the squared circle, just about yet.
