McCray made a name for herself in women's basketball as a world class defender. She was known for shutting down a number of the world's best players. She currently is an assistant coach at University of South Carolina. McCray 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. That mentality is instilled in Nikki, and I want people around me like that. She is energetic, confident and engaging – all qualities that you need when you're coaching and recruiting. We spent two Olympic Games together and have shared being successful in the very best arena there is to test yourself." 
In addition to her career on the court, McCray also created a name for herself in the realm of community service. In the year 2000 Nikki McCray was hand-picked by President Bill Clinton to be made a member of the President’s Council on Physical Fitness and Sports. At the age of 28 McCray had since moved on from her days as star player for the Lady Vols at her alma mater, the University of Tennessee, and on to becoming the star of a new team the Washington Mystics. 2000 was a good year for McCray; in addition to being named a member of the President’s Fitness Council, she was also chosen for the 2000 USA Olympic basketball team.
In 1999 The Library of Congress selected Nikki McCray to be the keynote speaker for the Women’s History Month Address. "We are pleased to have Ms. McCray with us to kick-off our month long celebration of women's history," said Federal Women's Program Manager Jean Parker. "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."
