The AFA continued to grow - some said too much, too fast as the league ballooned to 20 clubs for the 1923 season, its fourth campaign. Several names that would last for a very long time were there, near the top as the Detroit Maroons, Chicago Wildcats and Cleveland Finches all enjoyed successful seasons. But the team that finished first was also finishing for the last time.
Despite being one of the AFA's best teams since the league's inception, the Pittsburgh Pros were also probably the worst-run franchise in the league - and that was saying something. So while the team on the field was demolishing opponents and finished with an unblemished 12-0-0 record, the John Oxendine-led front office was losing money hand over fist. In the end, the 1923 championship season would be the last for the Pittsburgh Pros. Pro football wasn't gone forever in the Steel City, but the city's original franchise sunk in an ocean of red ink, it's players moving on to other clubs.
