Now, THIS is a maximum cool idea. Many years ago I played a board wargame that represented football, and like others, I agree that American-style football lends itself to this. [:)]
The game you are thinking of was probably "Scrimmage" from SPI and it was one of their S&T Magazine games. A "game" was basically 4 downs to see if you could make 10 yards. Interesting concept, but it was never really popular and quickly dropped from sight.
It was a bit interesting to see an offensive tackle counter that functioned pretty much like an Armored unit with similar "combat" (physical and skill factors) on it. You basically had "combat" as two players (counters) got into each other's zone of control. If nothing else, it made you realize that Football is a wargame.
