Collier was drafted by the
Milwaukee Bucks with the 15th overall pick of the
2000 NBA draft. He was traded on draft day to the
Houston Rockets in exchange for their pick,
Joel Przybilla. He then played for the Rockets and the
Atlanta Hawks, averaging 5.6 points per game over his career. With the Hawks, Collier dropped a career-high 22 points on March 12, 2004, in a 138–124 win against the
Washington Wizards. Out of the 151 career games Collier played, this was one of only three times where he scored 20 or more points. Collier's final NBA game was played on April 20, 2005, in a 86–110 loss to the
Philadelphia 76ers (this was also the Hawks' final game of the 2004–2005 season). Although he was Atlanta's starting center for that game, he only played for nine minutes and had two points and one rebound on 1-4 field goal shooting. == Death and legacy ==
