Haley was drafted in 1987 by the Chicago Bulls and made his NBA debut on November 9, 1988. After several years playing elsewhere, Haley returned to the Bulls as a free agent in October 1995 and was a member of the
1995–96 Bulls team that won a league record 72 games and the
NBA Championship. However, Haley spent almost the entire season on the injured list with tendinitis in his left knee. As a result, he only played in one game during the regular season and did not participate in the playoffs. At one point, another unidentified team complained to the league office, which sent out a doctor to examine Haley's knee. Haley was mainly known for his friendship with
Dennis Rodman, and was sometimes referred to as Rodman's "babysitter". However, Haley bristled at the label, and argued that he had legitimately earned his spot on the team. ==NBA career statistics==
