The Hawks are trying hard to trade Marvin Williams, who has two years and more than $15 million left on his contract after this season.

He also has a player option for 2013-14 worth $7.5 million.

"For what he makes, it's a tough sell," said one NBA coach.

Atlanta wants to acquire Kirk Hinrich from Washington, but they haven't been able to sell the Wizards on taking back Williams.
