No, they wanted Daniel Bryan to win. Simple as that.
Also fuck that "believeability" shit already. It's wrestling, it's fake. If it was real, Lesnar would rip Reigns to pieces, because Reigns has zero fighting background and is physically less than Lesnar.
It's only ever about a believable match, not a believable fight. "But he looks strong" is a shitty reason.
They didn't really want Bryan to win, when he got out the crowd gave no reaction or boos, they started doing it only after realizing that Reigns was the only one that could win after that point.
And i know it's Wrestling its fake but what makes it interesting is that you actually believe in the situation, it has some kind of logic behind it. If Orton or Cena were the champions I wouldn't complain but we're talking about someone that ended Taker's streak and squashed Cena vs someone that got injured by Kane and lost his returning match to Bray.
