"I don't understand why it exists as a popular sport anyways, it's 5 seconds of action followed by 30 seconds of two guys talking about it. The average football game has 11 minutes of action[1]. Everything but the last ~8 minutes of the 4th quarter is boring. Yet Americans love it. I don't get it."
better framed as a question like such:
"I'm not quite sure I understand the American fascination with football. Can someone provide context?"
