After spending four and a half seasons in Phoenix, Joe Johnson left the team after the season and signed with the Atlanta Hawks.
The Suns drafted Luol Deng with the 7th pick, who was immediately traded to the Chicago Bulls for second-round pick Jackson Vroman and a 2005 first-round pick. The Suns received the 16th pick (Kirk Snyder) in a trade with the New York Knicks, but traded the pick to the Utah Jazz. The Suns second-round pick was traded to the Orlando Magic in 2003.
After trading Stephon Marbury (owed $76 million through 2008–09) and Penny Hardaway (owed $30.4 million through 2005–06), the Suns freed enough cap space to sign free agent point guard Steve Nash to a 6-year, $65.6 million deal, with a sixth-year team option, and swingman Quentin Richardson to a 6-year, $43.5 million deal, with a sixth-year player option. The Suns also signed Steven Hunter, Yuta Tabuse and Derrick Dial as free agents.
