New York Yankees (NFL)

The Yankees arose as a result of a contract dispute between Grange and his previous team, the NFL's Chicago Bears.

During the early 1920s, Grange was the star attraction for the Bears, and his play had done a lot to promote the fledgling NFL.

Mara had just struggled through his first year as an owner, and was saved from financial disaster ironically by Grange's exhibition appearance.

But Grange's appearance drew 73,000 people to the Polo Grounds; in one afternoon Mara was in the black financially, and professional football had gained new respect among New York's influential sportswriters.

In comparison, an NFL game a week later in the same stadium between the Frankford Yellow Jackets and the New York Giants drew only 10,000.

Although the Brooklyn Horsemen disbanded after its last NFL game, the team's franchise was never withdrawn or canceled by the league.

The agreement between the two rivals limited the number of home games that the Yankees were permitted to play in its namesake stadium (four in 1927) and forced to be primarily a road team displaying the talents of Red Grange.
