The [drag force on an American football](http://users.df.uba.ar/sgil/physics_paper_doc/papers_phys/fluids/drag_football.pdf) is in the range of a coefficient of .05 to .06.  If the football is spinning the drag is slightly less.

The [drag on a FIFA soccer ball](https://www.grc.nasa.gov/www/K-12/airplane/socdrag.html) is a coefficient of .25.

The football should travel further.  The diameter of an American football is about 17.3 centimeters.  The diameter of a FIFA soccer ball is roughly 22 centimeters.  The greater cross sectional area of the soccer ball creates a thicker wake and more drag, as Sebastian Riese points out in his comment.

Another difference between the balls which produces greater drag on the soccer ball is the shape.  The American football's wake is significantly thinner than the soccer ball's, to a great extent because of the shape of the ball.  The hulls of ships, for example, are designed like a football's shape below the water line toward the stern in order to allow a more laminar flow as the boundary layer separates from the back of the ball.
