Turns out Azubuike was included in the trade. The trade is Zeller + Azubuike for Cunningham, Crowder, James.
Mavs save 1.4 million on move.
Azubuike was picked up as a potential defensive stopper with great range (a one time 40% three-point shooter), but he had been out of basketball for two years prior to landing with the Mavs and never saw much of the court for them.
