Golden State Warriors forward David West announced his retirement on Thursday, one day after celebrating his 38th birthday. The two-time All-Star posted a message on Twitter: "We are but a collection of our experiences I have been fortunate enough to live out my childhood dream of playing in the NBA. Belief in yourself is non-negotiable." The 18th overall pick in the 2003 NBA Draft, West averaged 13.6 points, 6.4 rebounds and 2.2 assists in 1,034 games over 15 NBA seasons, playing for the Warriors, San Antonio Spurs, Indiana Pacers and New Orleans Hornets.
