#1 Roman Reigns and the future of the Universal Title feud after WrestleMania Backlash

The Universal Championship picture has been kept interesting for all of Roman Reigns' Title reign, and he headlined WrestleMania Backlash. In his second Championship defense post-WrestleMania, Roman Reigns faced Cesaro.
The tension with Jimmy Uso was looming and we had a couple of segments featuring The Usos at WrestleMania Backlash. While Jey Uso wanted to accompany Roman Reigns to ringside, he didn't, but it made no difference.
Roman Reigns choked Cesaro out clean and post-match, the Swiss star seemed to get up in shock, unaware of what happened. Post-match, Seth Rollins came out and had a face-to-face confrontation with Roman Reigns before proceeding to attack Cesaro.
But that wasn't before Jey Uso had already come out, put a garland on Roman Reigns, and attacked Cesaro himself.
This could mean one of two things. The first one is that Seth Rollins will weasel his way into the Universal Title picture alongside Cesaro or they're splitting off into a separate rivalry for Hell in a Cell.
It doesn't make much sense for the Cesaro-Rollins feud to continue, but if it does, Jimmy Uso could be the man challenging Roman Reigns next. That would be an interesting direction as well.
