The 2003 NBA draft class is one of the greatest of all time, with LeBron James, Carmelo Anthony, Chris Bosh and Dwyane Wade all having carved out Hall of Fame-caliber careers. The remaining Top Five pick from that class, however, has seemingly decided to give up on basketball and try something else.

Darko Milicic, the No. 2 overall pick in the 2003 draft, is now pursuing a career as a kickboxer in Belgrade, Serbia, NBASerbia.com reported Monday. According to the report, he's set to sign a contract with the World Kickboxing Association on Wednesday.

You can see some of Darko's training below, via EuroHoops.net:

The 7'0", 275-pound big man played for six teams in his 10-year NBA career, averaging 6.0 points, 4.2 rebounds and 1.3 blocks per game. The 29-year-old played one game for the Boston Celtics back in 2012 but has not appeared in a game since.

The Detroit Pistons drafted Milicic right behind LeBron and ahead of Carmelo, Bosh and D-Wade. Given the success the latter three went on to experience, passing on them is a mistake that continues to haunt the franchise to this day.

Here's hoping Milicic's kickboxing career goes better than his NBA one did.
