Chargers linebacker Donnie Edwards, a Chula Vista native, will be moving on ? if not real soon then at least sooner than he would like. General Manager A.J. Smith verified when asked yesterday that he has notified the rest of the NFL (except AFC West foes) that Edwards is available for trade. Smith would not confirm what might pry Edwards away, but it is a good bet a first-day draft pick would accomplish it. ?If it's not attractive, nothing will be done,? Smith said. ?If it is, decisions will be made.?
