The USBA is a long-running online OOTP league started in 2013.
USBA is comprised of three leagues in a promotion-relegation format. The top tier is the 10-team Premier League, the middle tier is the 10-team Silver League, and the lower tier is the 12-team Menard’s Third League.
Each league plays a 108-game regular season, and there are also two inter-league competitions: The USBA Cup, including all 32 teams with group and knockout play, and the post-season Tournament of Champions including the top four teams from the Premier League, and the league winners of the Silver and Third League.
The league sims one three-game regular season series every weekday, and uses the OOTP real-time sim functionality to show every game as it happens.
