The crowd in the second fight was massively in fury favor what changes happened that the crowd was rooting for wilder?
The difference was who they were wagering on. In Nevada, fight attendees tend to cheer for the people they gambled on. And when you hear people cheer wildly at the end of a round that wasn't particularly exciting, it's because they bet the over/under in completed rounds. "YEAH, it went seven." (Not that the seventh round was all that great.) For fights in halls around the world, the reason people cheer tends to be different. But Nevada is Nevada.
