#4 Rollins cheats or gets help from Murphy to win at WrestleMania 37
Murphy is a part of the Andre the Giant Battle Royal on the SmackDown episode prior to WrestleMania 37. Once the angle with the Mysterios ended, it seems creative had nothing for Murphy. This is a shame since he's proven to be an extremely gifted performer in the ring.
There was a point during the build of the feud with Cesaro where Murphy returned to Seth Rollins' side. Rollins didn't want anything to do with him at first, but the two had a loose alliance against Cesaro and Nakamura.
The former Universal Champion was ringside for a match between the Swiss Superman and Murphy. Cesaro would win but Rollins didn't care, as he would attack his WrestleMania 37 opponent right after the bout ended.
Rollins' anger, along with his outlandish suits, has only highlighted his delusion. Getting swung a lot by Cesaro has also made Rollins seem more paranoid than ever.
The Messiah has shown he isn't afraid to sneak attack someone or use underhanded tactics to get his points across. He's attacked both Nakamura and the Swiss Superman from behind and could very well do the same at WrestleMania 37.
Since Murphy was briefly back in alliance with Rollins, it wouldn't be a huge shock if he somehow costs Cesaro the match. He might be trying to get back on Rollins' good side, since he is finished with the Mysterios.
The former Cruiserweight Champion also lost to Cesaro on a previous episode of SmackDown, as we discussed earlier. That probably hasn't sat well with him. He could very well show up to try and distract the Swiss Superman in order to help Rollins win.
While this seems like a match Cesaro should be booked to win, anything can happen. Cheating to win at WrestleMania is a high possibility given the shady nature of Rollins.
