CHARGERS SHOPPING TRIO OF VETS A league source tells us that the San Diego Chargers currently are shopping three veteran players -- safety Hanik Milligan, cornerback Sammy Davis, and linebacker Donnie Edwards. Edwards is under contract through 2007, and he's scheduled to make $3.55 million in 2006. Davis' deal runs through 2009, with relatively manageable salaries. Milligan is scheduled to earn $460,000 in 2006, the final year of his rookie deal. Milligan made it to the 2005 Pro Bowl as a special-teamer, and word is that he's staying away from voluntary workouts in an effort to get a new contract. The efforts to move Edwards and Davis could be a precursor to a post-June 1 release of either or both of them.
