Knicks Add More Sharp-Shooting in Quentin Richardson

The Boston Celtics first round opponent this spring is adding some insurance to their roster pretty late in the game.

With only one or two games left for NBA teams, the New York Knicks have made a move to sign Quentin Richardson to the roster.

Richardson will be eligible for the postseason, as he was not on another roster on March 1, per Steve Bulpett of the Boston Herald.

Bulpett's Pierce comment seems to stem from unknown origins. According to a Yahoo! story, the two were friends at the University of Kansas, but were ejected for arguing at some point during Richardson's first run with the Knicks.

Richardson also played for the Miami Heat when the Celtics eliminated them in five games during the 2010 playoffs. In that series, he and Kevin Garnett got into an altercation after Richardson wouldn't exit the Celtics huddle. Garnett caught Richardson with an elbow and was suspended for Game 2 of the series.

The Celtics won Game 2, 106-77, courtesy of Glen Davis' 23 points in a starting capacity.

Richardson last played a year ago for the Orlando Magic. In 48 games during the 2011-12 season, he averaged 4.5 points and 2.6 rebounds in 18 minutes per game.

The Knicks are the league leaders with 29 three-point attempts per game, and the long ball was always Richardson's speciality. He is a career 35.5 percent shooter from beyond the arc, and presumably adds depth to the Knicks' crew of long-range bombers.

This adds some intrigue to the series, as Richardson has feuded with both Celtics' superstars. However, Richardson may be just a deep bench addition, after Rasheed Wallace re-injured himself Monday night.
