The Bulls have offered Tyson Chandler a guaranteed contract in the neighborhood of Samuel Dalembert's six-year, $64 million deal with Philadelphia, which isn't a stunning development given the similarities between the two big men.

In Chandler's case, however, it doesn't seem to be enough.

A source familiar with the negotiations confirmed the offer, and it is believed the Bulls are offering incentives that could make the deal more lucrative for their 7-foot-1-inch restricted free agent.

Just how much guaranteed money Chandler wants is unclear. His agent, Jeff Schwartz, did not respond to a message left Monday afternoon.

An agreement doesn't appear imminent, but Bulls general manager John Paxson said he isn't discouraged, perhaps because he and Schwartz have a strong rapport.

"We feel we're treating Tyson fairly in this," Paxson said. "Both Jeff and I feel we've made good arguments for our sides and have brought up concerns for both of us. Both sides are operating in good faith."
