I suppose the subject sums it up: does anyone know of a system or game in itself that has something similar to playable football? Even a pen and paper football game would be cool.

Thank you!

Bloodbowl?  Way more fun than regular football.

I second Blood bowl.

There's Strat-o-Matic football.  There's a computer version and a card version, but it might not be exactly what you're looking for:  http://www.strat-o-matic.com/products/football
