The Knicks have signed veteran swingman Quentin Richardson for the remainder of the season, GM Glen Grunwald announced today. Richardson, who played for the Knicks from the 2005-06 through 2008-09, last played in the NBA in 2011-12 where he appeared in 48 games for the Magic. Richardson has averaged 10.3 points and 4.7 rebounds in 782 games during his 12-year career. Richardson adds yet another threat from beyond the arc for the Knicks, who released Solomon Jones in order to clear a roster space. Richardson is a career .398 shooter from 3-point range and has experience in the postseason, playing in 31 games and averaging 8.5 points and 4.3 rebounds. The Knicks will be allowed to use Richardson in the playoffs because he was not on an NBA roster as of March 1. The team was also looking at Delonte West, who has been playing in the D-league, as a potential signing. With the impending return of Tyson Chandler and Kenyon Martin, the Knicks’ depth at the forward/center position is no longer a major concern.
