The Detroit Pistons have traded forward Ronald Dupree to the Minnesota Timberwolves in exchange for a future second- round draft pick. Dupree appeared in 47 games last season and averaged 10.0 minutes, 3.2 points and 2.0 rebounds. "Ronald is a solid defensive player and we wanted to get another big defender at the small forward position," said Timberwolves vice president of basketball operations Kevin McHale. "He is a guy that we have looked at in the past and we are glad that we were able to add him to the team." The 6-foot-7 Dupree spent the 2003-04 season with the Huntsville Flight in the National Basketball Development League. He then signed for the reminder of the season with the Chicago Bulls, appearing in 47 games. The move will clear a roster spot for Pistons rookie guard Alex Acker, who was the 60th and final pick of June's NBA draft. Meanwhile, Minnesota waived forward Ndudi Ebi.
