The Dallas Mavericks are aggressively looking to trade, but they don't want to limit their future financial flexibility.

"The thing that Mark has brought is the ability to hit the grand slam home run," Nelson, the Mavs? GM, said Wednesday from Chicago, where he planned to watch the University of Connecticut play. "You have an owner who is a proven, willing spender if the right deal comes along, and you can count those guys on one hand right now. Almost everybody is looking to cut back.

"I don?t want to take that card away from Mark in 2010, because he?s shown he?s capable of pulling a rabbit out of his hat."
