and George Karl (Montana Golden Nuggets). In 2001, the NBA formed its own minor league, the National Basketball Development League (the NBDL or "D-League"). At the end of the 2005–2006 season, three current and one expansion CBA franchises jumped to the NBDL. During the 2006–07 season no players were called up from the CBA to the NBA, ending a streak of over 30 seasons of at least one call-up per year. That would soon lead to the beginning of the end for the CBA. In 1987 the CBA announced that they would allow teams to sign players banned for drug use by the NBA. Mitchell Wiggins, who was suspended by the NBA for cocaine use, was one of the first players signed in the CBA under the new rule that was implemented in conjunction with the NBA and NBA Players Association. Rules and innovations The CBA followed largely the same basketball rules as the NBA and most other professional leagues. Sometimes rules adopted by the CBA on an experimental basis later became permanent in that league and were adopted by other levels of basketball as well; others remained unique to the CBA. From 1978 through 1986, CBA commissioner Jim Drucker created several new rules to raise fan interest, which were then adopted by the league: Season standings were changed from a win–loss percentage, to the "7 Point System". During each game, seven points were awarded—three for winning the game, and one point for each quarter in which a team outscored their opponent. (If each team scored the same number of points in a quarter, the point for that quarter was halved.) Team standings were determined by the number of points, rather than win–loss percentage. A player could not foul out of the game; after a player's sixth personal foul, the opposing team receives an automatic free throw. During the 1982–83 and 1983–84 seasons, overtime games were decided by the team that scored the first three points in overtime. During the 1984–85 season, that rule was modified so that victory went to the first team to lead by three points in overtime. By the 1987–88 season, that rule was superseded by a standard five-minute overtime period to determine the winner. During the 1981–82 season, the CBA created a "no call box"—an area in front of the baskets in which any contact in the box between offensive and defensive players was to
