Professional sports leagues in North America are made up of a certain number of teams known as franchises, each of which fields one team. The majority of the teams in the four major North American leagues were formed as a result of a planned league expansion or the merging of two rival leagues. In some cases, such as with the Montreal Canadiens and New York Knicks, a franchise was given its name before it became part of the league. The first six teams were awarded to owners who had been selected by A.C. Greenburg, a prominent baseball owner, on January 8, 1946. The first game played by a franchise after their official introduction into the league took place that same day between the Boston Celtics and Philadelphia Warriors. The Celtics won this match-up 97-93 at Fenway Park in Boston. Bob Cousy was named the first captain of the Celtics. In July of that year, the National Basketball League (NBL) merged with the American Basketball Association (ABA) to form the current NBA. The Celtics were one of the twelve original teams of the NBA. The franchise has won more games than any other team in NBA history. Currently, the Celtics play their home games at the Verizon Center in Washington, D.C., and are led by head coach Brad Stevens. The Charlotte Hornets originated as the Atlanta Hawks' minor league affiliate until 1972 when they were granted an NHL franchise.
