Erick Dampier is prepared to leave the Mavericks if he does not get a deal worth the full mid-level exemption, which will be around $6 million.
Dampier has a $13 million non-guaranteed contract, which could be a big trading chip for the Mavs. A team can trade for him and then immediately cut him, and his non-guaranteed salary wouldn't count on their books. And if the Mavs can't trade him, they're going to cut Dampier, and then hope to re-sign him at a discounted price. However, they are probably not looking to give Dampier MLE money, and may just let him go as an unrestricted free agent.
