Just show 3 hrs of advertisements, then follow the ads with a circle of refs, the captains, and a coin flip. Whoever wins the coin flip ... wins the game.
With the pro-offense lean of the NFL game today, it's pretty much the same thing. Whoever won the coin flip in that game would have won the game. Period.
The Offenses have every advantage, and if the Defense somehow miraculously makes a great play on the ball, another ref will throw a flag after the play for a penalty on the other side of the field, and give the Offense a 1st down.
