I just thought it would be funny to see an NFL ref spraying foam on the field to mark a turnover or first down, something.
THey’d go through a whole can before the commercials were over.
Uh, no. In the NFL the commercials are never over. I think it was the Wall Street Journal who did a study of the average time the game was actually played in the NFL. It turns out that the actual game play time in an average NFL game is only 11 minutes within the entire 3 hour spectacle.
From the time the QB hikes the ball until the play is whistled dead -- 11 minutes. The rest of the 3 hours is replays, commercials, huddles, sideline shots, and assorted chatter.
