Passage: The 1992–93 NBA season was the Spurs' 17th season in the National Basketball Association, and 26th season as a franchise. During the offseason, Terry Cummings suffered a serious knee injury and only played in the final eight games of the season. With the acquisition of Dale Ellis from the Milwaukee Bucks and signing free agent Vinny Del Negro, plus re-signing Avery Johnson after a brief stint with the Houston Rockets, the Spurs struggled with a 9–11 start to the season as new head coach Jerry Tarkanian was fired. After playing one game under Rex Hughes, the team hired John Lucas II as their new coach. At midseason, they acquired J.R. Reid from the Charlotte Hornets. Under Lucas, the Spurs would play solid basketball posting a 10-game winning streak in January, then winning eight straight in February, finishing second in the Midwest Division with a 49–33 record. David Robinson and Sean Elliott were both selected for the 1993 NBA All-Star Game.
