He added that he wasn't interested in the storyline because it didn't matter which star emerged victorious, and that it went on for far too long."I'm gonna throw out a very simple question to you. This Rusev and Sheamus has been going on for at least two months. I'm gonna ask a simple question. Why do I care if either one wins or loses? If Sheamus goes over because he's the babyface, what does that matter at all?" said Russo.Bryant @BryantkJohnsonLINKI miss Sheamus #WWERawIt will be interesting to see when the former WWE Champion returns to television in the weeks ahead.
