|National Football League seasons
The 1925 NFL season was the 6th regular season of the National Football League. Five new teams entered the league: New York Giants, Detroit Panthers, Pottsville Maroons, Providence Steam Roller, and a new Canton Bulldogs team. The Kenosha Maroons and Minneapolis Marines folded, with Racine Legion mothballing.
1925 NFL Championship controversy
Controversy surrounds who actually won the 1925 NFL Championship. Officially, the Chicago Cardinals are listed as the 1925 NFL champions because they finished with the best record; however, many Pottsville fans at the time claimed that the Maroons were the legitimate champions. The Maroons and the Cardinals were the top contenders for the title, with Pottsville winning a late-season meeting between them, 21–7. But the Maroons scheduled a game against a team of University of Notre Dame All-Stars in Philadelphia (and winning 9–7) on the same day that the Frankford Yellow Jackets were scheduled to play a game in the same city. Frankford protested, saying that it was violating their protected territory rights.
Although NFL president Joe Carr warned the Maroons in writing that they faced suspension if they played in Philadelphia, the Maroons claimed that Carr approved the game during a telephone call, and played anyway. In response, Carr fined the club, suspended it from all league rights and privileges (including the right to play for the NFL championship), and returned its franchise to the league.
In 2003, the NFL decided to again examine the case regarding the 1925 championship. But in October the NFL voted 30–2 not to reopen the case. Thus the Cardinals are still listed as the 1925 NFL champions.
