So I came up with a good trade for the Mavs.
Samuel Dalembert is much better than Eric Dampier. He is a better defender and rebounder. I thought he would be a better fit than Dampier and Philly wants expirings anyway and his contract is enticing.
Josh Howard and Barea both expirie in 2010 and are similar to Iguodala's so the cap works.
Kidd/ Terry/ Rodrigue Beaubois
Andre Iguodala/ Jet Terry/ Rodrigue Beaubois/ Carrol
Marion/ Ross/ Tim Thomas
Dirk/ Najera/ Tim Thomas/ Gooden/ Marion
Dalembert/ Gooden/ Najera
This is a much improved roster with the addition of Iguodala and Dalembert. Iguodala being a huge improvement over Howard and Dalembert is an improvement over Dampier.
