Well in all honesty it's just a midcard championship. This has happened before, Kane's reign was like this when he took the belt from Stone Cold and lost it on Raw is War the next night. This kind of stuff happens, and it just builds up on the feud and makes the rematch clause look like something good. Also The Miz had his Wrestlemania moment. Barrett might have won on Raw, but he didn't win on the grandest stage of them all, so Miz's victory wasn't a total waste. Also I would be excited if I won at Wrestlemania, I wouldn't care if I had to lose the belt the next night, I'd be grateful that I won on the most important night of the year, Wrestlemania.
