I heard him all broadcast! I love to see it. That is a great fan. He was not yelling anything inappropriate or profane. He was just supporting his team - loudly and passionately. And he kept it going for all 4 quarters somehow! I would have lost my voice at some point.
Can you imagine if every single fan in the stadium matched that level of intensity for the entire game!? It would literally be a frightening atmosphere to step into as an opposing team. I've never seen that though, at any professional sporting event, and suspect it will never be done. There will always be a % of "passengers" in the stands, casual fans, etc. And that is okay too.
