On Friday, the Mavericks agreed to an eight-player trade with the Golden State Warriors that brought high-scoring Antawn Jamison to Dallas.

On Monday, the trade should finally become official. The NBA is expected to give its approval following an early-afternoon conference call.

But the Mavericks might have more to announce Monday.

Donnie Nelson, the Mavericks' president of basketball operations, said his cell phone "exploded" on Saturday about the time news leaked about the impending deal.

"We're getting a lot of calls from teams that are interested in doing business," Nelson said, estimating that he's spoken to as many as 20 teams this weekend.

The Mavericks are scheduled to acquire Jamison, Danny Forston, Jiri Welsch and Chris Mills from Golden State for Nick Van Exel, Avery Johnson, Evan Eschmeyer and Popeye Jones. Team officials can't comment about the trade until it's completed.

Each of the incoming players is attractive, to the Mavericks and other teams, although Mills is the most likely candidate to be on the move, again. He has one year remaining at $6 million in his contract, a cap-friendly number for teams planning a year ahead.

He could be a bargaining chip that might be flipped for players who could provide inside help, although the top big men are long gone from the board. The eight-player deal also erased any possibility of the Mavericks signing free-agent center Vladimir Stepania.

Timing is important, too. If the Mavericks don't deal one of the new additions Monday, packaging it as a three-team deal, they must wait two months to package any of the four with a player off their current roster in a deal.
