Several years later, when the construction of the current high school was proposed, the team moved to Brown's Field.

In the early 1920s, the Frankford Athletic Association's Yellow Jackets gained the reputation of being one of the best independent football teams in the nation.

The Yellow Jackets assembled in September 1924 under coach Punk Berryman to begin preparing for the upcoming season.

The team included players Harry Dayhoff, Russ Stein, Bill Kellogg, Joe Spagna, Whitey Thomas, Al Bedner, and Bob Jamison.

After a 9–1 start in league play, Frankford lost several key players, including Chamberlin, to injuries.

After a 49–0 defeat to the Pottsville Maroons, Frankford's captain Bull Behman was suspended indefinitely from the team for indifferent play.

The Yellow Jackets began the 1926 season with an exhibition game against the Atlantic City Roses, which Frankford won 45–0.

The Yellow Jackets prepared for another two-game set, this time against the New York Giants, resulting in a pair of 6–0 Frankford victories.

This string of victories left Frankford in great shape in the standings as the team headed into its Thanksgiving Day game with the Green Bay Packers.

The Jackets' 14 wins during the 1926 championship season set an NFL record for regular-season victories that stood until 1984 when it was broken by the 15–1–0 San Francisco 49ers.

One day after capturing the title, however, Theodore "Thee" Holden and Guy Chamberlin stepped down as president and coach of the Frankford Athletic Association.

However, Moran's son Tom briefly served as the team's interim coach that year after Charley took a leave of absence to officiate in the 1927 World Series between the New York Yankees and the Pittsburgh Pirates.

Weir had fellow players Russ Daugherty, Charlie Rogers, and Swede Youngstrom serve as assistant coaches.

At the same time, however, the Association's management decided to retain only a few veteran players, replacing most of the squad with rookies direct from college.

This resulted in a string of ten consecutive losses (eight of which were in October), the worst losing streak in Yellow Jackets history.

To end the streak, Frankford purchased eleven players from the Minneapolis Red Jackets, and George Gibson took over the team's coaching duties from Behman.

However, the effects of the economic depression and poor performance on the field combined to reduce the team's fan base.

Before the start of the 1931 season, Frankford Stadium was severely damaged by a fire, forcing the club to find another location for its home games.

Philadelphia Municipal Stadium and Baker Bowl were located outside of the Frankford area, making attendance difficult for local fans.

Some members of the press began referring to the team as the Philadelphia Yellow Jackets, in an attempt to increase fan support, which failed to materialize.

By October, NFL President Joe Carr, after witnessing the poor attendance at Frankford's home loss to the Portsmouth Spartans, approved a plan for the Yellow Jackets to finish the season as a traveling team.

The Association also sponsored bus and train trips for fans to travel along to games in such places as Pottsville and New York City, where even the host teams' sportswriters took notice of their enthusiasm.

Additionally, Bell and Wray assembled an almost entirely new team; Art Koeninger was the only player from the 1931 Yellow Jackets on the roster of the 1933 Eagles.
