WWE WrestleMania 35: 10 Things That Must Happen
9. Roman Reigns & Drew McIntyre Go To A Non-Finish

This is Roman's first match back since beating cancer a second time, and it'll be an emotional one for a guy who has been booed out of the building on his past few trips to 'Mania. WWE need to remember that their product rolls on beyond New Jersey though, and that's why Reigns shouldn't beat Drew McIntyre cleanly.
Where do they go from there?
McIntyre has all the tools to be that credible challenger for the Universal Title during the usual post-show slump. He has presence, looks like a machine and can wrestle against all shapes and sizes. He shouldn't then be sacrificed just so Roman has that feel good comeback win. A non-finish would be fine in this instance.
WWE have 14 other matches (including the pre-show ones) to play with here. One screwy finish won't hurt, and Roman's return won't feel like a disappointment if he can't leap the first hurdle. This one has rematch written all over it, possibly with a gimmick tacked on.
