Coincidence is a hell of a thing. Some folks believe there are no coincidences. Others remain true to the idea there are plenty, and if not analyzed properly, lead to a path of misinformation and destruction.
In a non-coincidental fashion (I think), coincidences are important in the game of football. Other than the players and select employees of a particular team, many of the in-the-huddle calls and pre-snap adjustments are complete unknowns. Best guesses and football knowledge help get onlookers part of the way home, but the true story is hardly ever realized.
It’s why coincidence is important.
