#2 Seth Rollins (Universal Champion) vs Roman Reigns (WWE Champion)
With Seth Rollins winning the Universal Title at WrestleMania 35, fans were wondering who will challenge him for the title? One name that came to everyone's mind was his Shield-brother, Roman Reigns.
Thankfully, Roman has been drafted to SmackDown and would be away from the Universal Championship for the foreseeable future. But that doesn't mean he won't be in the title picture. If you know Vince, then you know that there is a good chance that he would book him against Kofi Kingston for the WWE Championship, and potentially even put the title on him, especially during the FOX network jump.
If this does happen, we might as well get to see two former brothers go down at it as the Universal and WWE Champions respectively, to determine brand supremacy. It would be amazing to watch these two go at it once more.
