What brand are the NBA jerseys in 2003?

In 2003, NBA jerseys were primarily made by Nike and Reebok, with Nike being the official provider for the league's apparel. However, during that season, many teams still had jerseys produced by Adidas, which had been the official outfitter before Reebok took over. The switch to a single brand provider occurred later, with Nike eventually becoming the exclusive supplier for NBA jerseys in 2017.
