She won gold medals at the 1996 and 2000 Summer Olympics, and she participated on America's 1998 FIBA World Championship team.

In 2000, she was named a member of the President's Fitness Council,[4] and was also chosen for the 2000 USA Olympic basketball team.

Her debut game was played on June 11, 1998, in a 57–83 loss to the Charlotte Sting where she recorded 19 points and 6 assists.

However, the team's playoff run was short lived as they were eliminated in the first round by the New York Liberty in two games.

[6] In the second game of that playoff series, McCray was held scoreless throughout her entire 30 minutes on the floor and shot 0–3 FG.

That game was played on June 21, 2006, and the Sky were defeated by the Fever 55–77 with McCray recording 1 steal and 2 rebounds.

She made a new home for herself at the University of South Carolina with a former teammate as head coach, Dawn Staley.

Staley said about McCray: "Nikki is hungry for success, and that comes from playing at Tennessee where the coach never settles for anything less than being number one at whatever she's doing.

[12] In addition to her career on the court, McCray also created a name for herself in the realm of community service.

In 1999 The Library of Congress selected McCray to be the keynote speaker for the Women's History Month Address.

"As an employee of the first women's professional basketball team in the nation's capital and through her community service, Ms. McCray is a wonderful role model for young people.
