Draymond Green is irked he won't be competing for a third gold medal this July at the Summer Olympics in Paris ... with the NBA star questioning the reason he was excluded.
Last week, Team USA revealed their 41-player selection pool ... of which 12 hoopers will eventually be named to the U.S. Men's Basketball squad that'll take on the world in France.
Grant Hill, the team's managing director, recently said Green wasn't included because of his on-court incidents this season ... believing Draymond needed to work on himself this summer, rather than hoop for Team USA.
