Background: Parker was born in Bruges, Belgium, and raised in France. His father, Tony Parker Sr., an African American, played basketball at Loyola University Chicago as well as professionally overseas. His mother, Pamela Firestone, is a Dutch model. Parker's great-uncle Jan Wienese is an Olympic gold medalist in rowing.
Context: Before the 2001 NBA draft, Parker was invited to the San Antonio Spurs' summer camp. Coach Gregg Popovich had him play against Spurs scout and ex-NBA player Lance Blanks. Parker was overwhelmed by Blank's tough and physical defense, and Popovich was ready to send him away after just 10 minutes. But after seeing a "best of" mix tape of Parker's best plays, Popovich decided to invite Parker a second time. This time, Parker made a better impression against Blanks; the Frenchman later described Blanks as a "one-man wrecking crew". But while Popovich decided that Parker was worth the gamble, the Spurs still had to hope that other teams would not pick Parker during the draft. Parker's name was barely mentioned in the pre-draft predictions, and the point guard was drafted 28th overall by the Spurs on draft day. After initially playing backup to Antonio Daniels, Parker became a starter and made 77 regular-season appearances in his rookie season, averaging 9.2 points, 4.3 assists and 2.6 rebounds in 29.4 minutes per game. When he played against the Los Angeles Clippers on 30 November 2001, he became the third French player to play in an NBA game, after Tariq Abdul-Wahad and Jerome Moiso. By the end of the season, the rookie led San Antonio in assists and steals, and was named to the All-Rookie First Team for 2001-02, becoming the first foreign-born guard to earn the honor. In 2002-03, Parker played in all 82 regular-season games as San Antonio's starting point guard on a team that was largely revamped from previous years. He improved his regular season statistics, averaging 15.5 points per game (ppg), 5.3 assists per game (apg) and 2.6 rebounds per game (rpg). Parker's role as the team's playmaker was reflected in his leading the team in assists on 49 occasions. During the 2003 NBA All-Star Weekend, Parker represented the Sophomores in the Rookie Challenge, and also participated in the inaugural Skills Challenge. In the post season, the Spurs, led by Tim Duncan, defeated the New Jersey Nets 4-2 in the finals, and Parker earned his first NBA championship ring. Despite the victory, Parker struggled with inconsistent play throughout the playoffs, and was often substituted for the more experienced guards Steve Kerr and Speedy Claxton late in the games.
