#3 Seth Rollins could turn face and challenge his old friend Roman Reigns

As things stand, Seth Rollins is currently on paternity leave as he and Becky Lynch welcomed their daughter, Roux, to the world earlier this week. He is likely to return at some point in January, possibly at the Royal Rumble. It would be quite the moment if he returns in the match and wins it, effectively turning babyface in the process. It would add a new layer to his storied saga with Roman Reigns.
Rollins and Reigns were together for years as part of The Shield, before The Architect broke up the group. The two stars have clashed on several occasions, with some interesting outcomes. Aside from Rollins' cash-in at WrestleMania 31, he and Roman Reigns faced off in a classic at Money in the Bank 2016. However, all of it happened with Rollins as the heel and Reigns as the face.
This time, the story would be different. Seth Rollins sacrificed himself for the 'greater good' at Survivor Series, which may end up in a face turn upon his return to WWE. He would be a great opponent for Roman Reigns at WrestleMania simply based on their history together and chemistry with each other.
It's been a while since Reigns and Rollins have interacted on-screen and since the two of them are on the same brand, WWE would be smart to take advantage. Babyface Seth Rollins vs. heel Roman Reigns was the match that everybody was clamoring for in 2016. It would work just as well in 2021, in the main event of WrestleMania.
