The Dallas Morning News (Eddie Sefko) reports: The Mavericks must decide if there is a reasonable market for players such as Josh Howard, Jason Terry and/or Jerry Stackhouse. Those are trade chips of varying value. But it’s about all the Mavericks have to dangle unless they want to make a serious change in philosophy and trade Dirk Nowitzki or admit the Jason Kidd trade was a mistake and deal him. Kidd enters the final year of his contract, worth $21 million. The Mavericks also will have Reyshawn Terry and Renaldas Seibutis, two former second-round picks, in summer league. Both are being given a decent chance of making next season’s roster. Meanwhile, some of the prominent names around the league who could be on the trading block are the LA Clippers’ Corey Maggette, Sacramento’s Ron Artest and Charlotte’s Gerald Wallace or Jason Richardson.
