Tyson Chandler, DeShawn Stevenson, J. J. Barea and Caron Butler were the guys who left after the title. Good players, but none has made an impact on the league since (and they later re-acquired Chandler). They signed 6-man of the year Odom and Vince Carter. Defensive downgrade, offensive upgrade. Next season Kidd and Terry left in FA, but both were at the end of their careers. Kidd was a coach within 2 years. The team was on the end of the age curve, and the rest of the top of the West has been insane with the Spurs, Thunder, and Warriors. Cuban's tried to get every major FA, but you can't force people to sign in Dallas. Just ask Deandre Jordan. He's had to settle for Monta, Chandler, etc.
