On March 8, 2002, he scored 21 points to help the Eastern Conference defeat the West 115–103, at the EA Sports Roundball Classic at the United Center in Chicago. At that point, he was rated #4 High School Player in the United States in the Prep Stars Recruiter's Handbook.
To his surprise and disappointment, in the 2002 NBA Draft, all 29 NBA teams passed on Cooke in both rounds. Because he was not selected, Cooke became a free agent, eligible to sign with any NBA team that wanted him.
That summer, after being bypassed in the NBA Draft, he played in the Rucker Park Summer League in New York for the Terror Squad team. Later in 2002, Cooke was drafted by the Columbus Riverdragons of the NBDL. In April 2003, he tried out for the Brevard Blue Ducks of the USBL, and in May 2003 was signed by the USBL's Brooklyn Kings. In 15 games, he averaged 28.8 points and more than 9 rebounds per game.
