Fan interest was diminishing after four seasons, with one game in the 1967–68 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.
