The United Basketball League is a spring semi-professional basketball league in the Southern United States. Founded by Mac Claire in 2006 as the Regional Basketball League, the UBL began its inaugural season in the spring of 2008. With an aim to provide stable, family-friendly basketball teams for all to enjoy, the UBL plays with 12 teams in cities with populations between 100,000-300,000 in Texas, Arkansas, Oklahoma, and Missouri.
Its rules and style of play include a shot clock shortened to 20 seconds and 5 seconds to advance the ball past midcourt to promote a consistently up-tempo game. Teams are geographically located to create a favorable travel schedule where players and coaches may return home on most nights.
