That's where the Mavs really miss Chandler. He could dive to hoop and get easy basket. Mavs were better with him on defense but drop off isn't that bad. Still the right move to let him go to Knicks.
They equally miss some snipers. When Dirk was doubled, he could kick it to Stevenson or Peja. After they made 2 or 3 in few minutes, teams would ease up on Dirk double teams. Kidd only shoots long ball when he has five seconds to prepare. Jet can get his own shot and hasn't been shooting that great anyway.
