The Raiders broke an unwritten rule and made the Chiefs angry. Bad idea

After a shocking start to the season, Kansas City look back to their best. So it was an odd decision for their opponents to give them added motivation on Sunday

It's hard to imagine what motivated the Las Vegas Raiders to prance to the middle of Arrowhead Stadium and stomp on the Chiefs' logo during pregame warmups. You don't want people coming into your stadium and disrespecting what you've built," Patrick Mahomes would later say.

There is no official rule against what the Raiders did but there are also things called etiquette and common sense. And as the Raiders quickly learned Sunday, there's another thing called karma. Seventeen seconds into the game it was the Chiefs who were dancing after defensive tackle Jarran Reed caused a Josh Jacobs fumble, which cornerback Mike Hughes took to the house for the first of what felt like a million points for Chiefs. Twenty-one minutes later it was 28-0 Chiefs. The final score was 48-9. It was an embarrassment on all levels for Las Vegas. The Raiders' little pregame ritual certainly didn't help matters.
