The National Basketball Association (NBA) is a major professional basketball league in North America. It was founded in 1946 as the Basketball Association of America (BAA).[1] The league adopted its current name at the start of the 1949–50 season when it merged with the National Basketball League (NBL).[2] The league consists of 30 teams, of which 29 are located in the United States and one in Canada. In the NBA, a head coach is the highest ranking coach of a coaching staff. They typically hold a more public profile and are paid more than the assistant coaches.

He won six titles with the Chicago Bulls and five titles with the Lakers, and is one of three coaches who have won multiple championships with more than one team (Pat Riley and Alex Hannum are the others).
