#3 Shane McMahon vs The Miz
Since Crown Jewel, it has been incredibly apparent that the end game for Shane McMahon and The Miz is going to be a showdown at WrestleMania 35, and the duo look set to finally implode at this Sunday's Fastlane event.
After losing the SmackDown Tag Team Championships to The Usos at The Royal Rumble, The Miz's character has shown plenty of signs of snapping, and that will all likely come to a head at Fastlane.
The match is likely to involve some sort of miscommunication for the finish, and that, in turn, will lead to some sort of post-match attack, most likely from The Miz on McMahon.
#2 Kofi Kingston vs Daniel Bryan vs Kevin Owens
Kofi Kingston is riding a huge wave of popularity on SmackDown Live right now, and the WWE would be foolish to not cash in on that come WrestleMania 35.
Last week, WWE made the decision to take Kofi Kingston out of his scheduled match with Daniel Bryan at Fastlane and replace him with Kevin Owens. The logic behind that decision, presumably, was to build more sympathy for Kingston and to help build him up towards a big WrestleMania showdown.
The original plan, reportedly, for WrestleMania 35 was to have Kevin Owens take on Daniel Bryan, and while that could still end up being the match, it makes sense to add Kingston to the bout by having him somehow get involved in Sunday's showdown between Owens and Bryan.
