#4. Seth Rollins has lost steam since WrestleMania 35
There's no denying that Seth Rollins and his girlfriend and RAW Women's Champion Becky Lynch have both lost a considerable amount of steam since WrestleMania 35. Heading into the grandest stage of them all, Rollins had the third most momentum in the company, only behind Becky Lynch and Kofi Kingston on SmackDown Live.
While Kingston has managed to move forward as a very strong champion, Rollins has lost a bit of steam, which is why Vince McMahon may think twice before immediately putting the title back on him.
Since Roman Reigns has taken up a rather different role since his return, it's unlikely that we'll see The Big Dog go after Lesnar. Rollins has still been handpicked as "the guy" to take Reigns' place, but WWE knows that they have to rebuild his momentum to make him as hot as he was in early 2018.
