Input: Question: Who is the head of the National Basketball Association? Passage:The 1993–94 NBA season was the Spurs' 18th season in the National Basketball Association, and 27th season as a franchise. It was also their first season at the Alamodome. During the offseason, the Spurs acquired All-Star forward Dennis Rodman from the Detroit Pistons, and signed free agent Sleepy Floyd. Rodman led the league with 17.6 rebounds per game as the Spurs went on an 8-game winning streak after a 4–5 start to the season. The team would then win 13 consecutive games between January and February, and finish second in the Midwest Division with a 55–27 record. David Robinson captured the scoring title leading the league with 29.8 points per game, and was selected for the 1994 NBA All-Star Game. However, in the first round of the playoffs, Rodman became a distraction as he scuffled with head coach John Lucas as the Spurs lost to the 5th-seeded Utah Jazz in four games.
