Seth Rollins and Roman Reigns have known each other for a long time. Seth and Roman Reigns were both part of The Shield faction. Seth Rollins wanted to go to next level, so he decided to turn on The Shield and join Triple H’s Evolution faction.
Seth Rollins recently on Out of Character with Ryan Satin podcast talked about Roman Reigns. Seth feels if Roman Reigns had wrestled more matches then secondary title wouldn’t have been necessary.
If Roman was doing what I’m doing there wouldn’t really be a need for a secondary championship, there wouldn’t be a need for another World Heavyweight Championship on RAW, because we would have somebody who was doing those things and like you said it would give direction to the characters of the show, it would give directions to the show itself, but because of the route he has chosen and what he wants to do with his schedule and his title reign is not what I’m doing, somebody’s gotta fill that void.
We did our best with the US Championship for a while to do that but it never really felt like a World Heavyweight Championship, so there’s gotta be that person, that spot for everyone to get to and try and fight for, and I’m very happy to be that carrot that’s dangling there, and I think it’s a good thing, and again if Roman was doing all this stuff and defending the title all over the place then we wouldn’t have all these problems.
