"Sacramento has been aggressive in pursuing a new home for Bibby, who has suffered while trying to complement Ron Artest. The Kings offered him to Dallas for young point guard Devin Harris and Croshere's expiring money, according to NBA sources, but the Mavericks weren't going to risk the league's finest chemistry just two months before the playoffs."

Is Harris really this valuable?
