2. Avery Johnson
Unlike Simmons, Avery Johnson was not originally signed by San Antonio. He first played in the NBA in the 1988-89 season with the Seattle Supersonics, then was traded to the Denver Nuggets. He enjoyed short stints with the Spurs, Rockets and Warriors, before returning to San Antonio where he would remain for seven straight seasons.
At just 5'11", Johnson earned the nickname "The Little General," due to his small stature but big heart. He enjoyed the most productive seasons of his career in the Alamo City, and he was an intregal part of the Spurs' first championship team in 1998-99.
He is best known for hitting the game-clinching shot for the Spurs in Game 5 of the 1999 NBA Finals against the New York Knicks. The next season, he started all 82 games in San Antonio at 35 years old. Johnson's jersey was hung in the rafters of the AT&T Center in 2007, and he remains one of just 10 players in Spurs history to have their jersey retired by the franchise.
