Originally, over ninety teams plan were originally scheduled to compete during the 2011-12 season. However, much of that list included teams that had no plans to start the season and teams which disappeared before the season began. Of the teams listed, East Kentucky Energy and Chi-Town Bulldogs disappeared before the season began. Midwest Flames folded, with players and coaches joining another team. St. Louis Pioneers and Indiana Diesels both left to join the Premier Basketball League. Tampa Bay Rain and Greencastle Golden Knights were originally set to start the season, but were moved to expansion teams for the next season.
This season was the first full season where the league released scores from games played.
