1999–2000 Seattle SuperSonics season

The SuperSonics had the thirteenth overall pick in the 1999 NBA draft, and selected shooting guard Corey Maggette out of Duke University, but soon traded him to the Orlando Magic in exchange for Horace Grant. The team also acquired Brent Barry from the Chicago Bulls, and signed free agents Vernon Maxwell, second-year forward Ruben Patterson and three-point specialist Chuck Person.

Two years removed from the George Karl-era, the SuperSonics held a 31–20 record at the All-Star break, and managed to qualify for the NBA playoffs after a one-year absence, finishing in fourth place in the Pacific Division with a 45–37 record, and earning the #7 seed in the Western Conference.

In addition, Vin Baker averaged 16.6 points and 7.7 rebounds per game, while Barry contributed 11.8 points and 1.3 steals per game, and also finished second on the team with 164 three-point field goals, Patterson showed improvement averaging 11.6 points and 5.4 rebounds per game, and Grant provided the team with 8.1 points and 7.8 rebounds per game. Off the bench, Maxwell contributed 10.9 points per game, but only played just 47 games due to a knee injury, and second-year forward Rashard Lewis provided with 8.2 points and 4.1 rebounds per game.

Payton also finished in sixth place in Most Valuable Player voting, and tied in fifth place in Defensive Player of the Year voting, and Patterson finished tied in sixth place in Most Improved Player voting, while Lewis finished tied in eleventh place.

In the Western Conference First Round of the 2000 NBA playoffs, the SuperSonics faced off against the 2nd-seeded Utah Jazz, where they lost the series in five games. Following the season, Grant was traded to the Los Angeles Lakers after only one season in Seattle, while Maxwell was traded to the New York Knicks, but was released to free agency, and re-signed as a free agent with the Philadelphia 76ers, and Person retired.

For the season, the SuperSonics added new dark red alternate road uniforms, which remained in use until 2001.
