NBA legend Paul Pierce says he's ready to hang 'em up ... after ONE MORE run at an NBA title.
The Truth just released a video statement on The Players' Tribune -- and says he's realized that it's time to move on from the game of basketball ... "It's my final season."
Pierce says he's at peace with the decision -- and says he believes the Clippers are legitimate title contenders.
He also admits, "It's a young man's game" ... but says he thinks he has one more opportunity "with a great team."
Pierce was drafted by the Celtics with the 10th pick in the 1998 Draft -- and led the team to an NBA title in 2008.
