DALLAS (AP) -- The Dallas Mavericks finally made a major offseason move, acquiring Antawn Jamison in a nine-player trade with the Golden State Warriors.

The Mavericks also got Danny Fortson, Jiri Welsch and Chris Mills from the Warriors for Nick Van Exel, Avery Johnson, Evan Eschmeyer, Popeye Jones and Antoine Rigadeau.

The 6-foot-9 Jamison has averaged 20.2 points a game in his five NBA seasons, and has been the Warriors' top scorer the past four seasons.

Van Exel was the Mavericks' leading scorer off the bench last season. During the playoffs, when Dallas advanced to the Western Conference finals before losing to San Antonio, Van Exel averaged 19.5 points.
