Bulls also are exploring interest in Luol Deng / Berger, CBS

In addition to peddling Kirk Hinrich, sources say the Bulls also are exploring interest in Luol Deng, who has four years and $51 million left after this season. Trading both of them – or packaging one of them with Thomas – would provide Chicago with enough cap space to score two max free agents this coming summer, effectively placing them on equal footing with the Heat in the 2010 chase.
