It is really rare to read something on the internet that you haven’t at least tangentially come across before, so: THIS IS SOMETHING I HAVE NEVER READ ON THE INTERNET.
That is a brief but wild article on The California Tiebreaker. The format of The California Tiebreaker is butt-simple. The ball starts on the fifty. The winner of the coin toss gets possession, and each team receives four plays to move the ball however they like in the direction of the other team’s endzone.
The weirdness kicks in here: Each team trades possessions, and works the ball from the spot where their opponent left it on the previous play.
