<P> On January 16, 1966 Chicago was granted an NBA franchise to be called the Bulls . The Chicago Bulls became the third NBA franchise in the city, after the Chicago Stags (1946--1950) and the Chicago Packers / Zephyrs (now the Washington Wizards). The Bulls' founder, Dick Klein, was the Bulls' only owner to ever play professional basketball (for the Chicago American Gears). He served as the Bulls' president and general manager in their initial years . </P> <P> After the 1966 NBA Expansion Draft, the newly founded Chicago Bulls were allowed to acquire players from the previously established teams in the league for the upcoming 1966--67 season . The team started in the 1966--67 NBA season, and posted the best record by an expansion team in NBA history . Coached by Chicagoan and former NBA star Johnny "Red" Kerr, and led by former NBA assist leader Guy Rodgers, guard Jerry Sloan and forward Bob Boozer, the Bulls qualified for the playoffs, the only NBA team to do so in their inaugural season . </P> <P> In their first two seasons, the Bulls played most of their home games at the International Amphitheatre, before moving to Chicago Stadium . </P> <P> Fan interest was diminishing after four seasons, with one game in the 1968 season having an official attendance of 891 and some games being played in Kansas City . In 1969, Klein dropped out of the general manager job and hired Pat Williams, who as the Philadelphia 76ers' business manager created promotions that helped the team become third in attendance the previous season . Williams revamped the team roster, acquiring Chet Walker from his old team in exchange for Jim Washington and drafting Norm Van Lier--who was traded to the Cincinnati Royals and only joined the Bulls in 1971--while also investing in promotion, with actions such as creating mascot Benny the Bull . The Bulls under Williams and head coach Dick Motta qualified for four straight playoffs and had attendances grow to over 10,000 . In 1972, the Bulls set a franchise win - loss record at 57 wins and 25 losses . During the 1970s, the Bulls relied on Jerry Sloan, forwards Bob Love and Chet Walker, point guard Norm Van Lier, and centers Clifford Ray and Tom Boerwinkle . The team made the conference finals in 1975 but lost to the eventual champions, the Golden State Warriors, 4 games to 3 . </P>

Who did the bulls beat to win their championships
