#4. Seth Rollins could be called upon to go up against Vince McMahon at WrestleMania
As previously noted, Seth Rollins doesn't yet have a WrestleMania match, and if he loses the RAW Tag Team Championship shot he has coming up, he may not even have a part to play in this year's show.
Rollins is one of the company's hottest talents, but he's arguably been held back in recent years. The Visionary has been mired in the mid-card now for a while now whilst Brock Lesnar and Roman Reigns take the spotlight.
It's clear who pulls the strings backstage, and given Rollins' new character, there is no reason he couldn't track down the WWE Chairman and demand answers.
If Rollins and Vince McMahon were to get into some sort of altercation, then while it would make sense for McMahon to ask Theory to do the job, Vince could decide to teach Rollins a lesson himself.
At 76 years old, McMahon should be looking for someone to step in the ring in his place, but this is the WWE Chairman we're talking about. He's never been known to shy away from a fight before.
