The 2. Basketball Bundesliga is the second level league of the German professional basketball league system. Until the 2007–08 season, the 2. Basketball Bundesliga consisted of two geographical divisions (North and South). Since 2007 the 2. Basketball Bundesliga now consists of two leagues, ProA and ProB. At the end of each season, the top two teams of the ProA are promoted to the Basketball Bundesliga, and the teams positioned 15th and 16th are relegated to the ProB.[1]
