The Fort Worth Star-Telegram reported that, in an eight-player deal, the Warriors got shooting guard Nick Van Exel and the Mavericks got forward Antwan Jamison.
The paper said Golden State also will get center Evan Eschmeyer, forward Popeye Jones, and veteran point guard Avery Johnson. Going to Dallas are power forward Danny Fortson, small forward Chris Mills, and guard Jiri Welsch.
Jamison and Van Exel, who was stellar for the Mavericks in the playoffs last season, easily were the key players in the deal. The trade cannot be approved until the NBA offices open on Monday.
Jamison, a former No. 1 draft pick by Toronto in 1998, led the Warriors in scoring last season, averaging 22.2 points and 7.0 rebounds per contest while playing in all 82 games for the third straight season.
Van Exel was the Mavericks' second-leading scorer in the postseason last season, when he averaged 19.5 points per contest.
