Related documents: [0]  [DOC] The 2004–05 NBA season was the 59th season for the Boston Celtics in the National Basketball Association. The season is memorable when the team hired Doc Rivers to be their head coach for the upcoming season. During the offseason, the Celtics acquired All-Star guard Gary Payton, and former Celtics forward Rick Fox from the Los Angeles Lakers, but Fox would retire before the season. The Celtics struggled playing under .500 for the first half of the season. At midseason, Payton was traded to the Atlanta Hawks for former Celtic All-Star forward Antoine Walker. However, Payton would never suit up for the Hawks and was released shortly after. He then re-signed with the Celtics afterwards for the remainder of the season. The team went on a 7-game winning streak in March, finishing first place in the Atlantic Division with a 45–37 record. Paul Pierce was selected for the 2005 NBA All-Star Game. [END]
