The Eagles' search for their next general manager has focused on "four or five" candidates, and a new hire could be made within 36 hours, a league source said last night. Howie Roseman, the Eagles' vice president of player personnel, was the only candidate identified by the source, and it is believed that he remains the leading candidate to replace Tom Heckert, who was hired as the Cleveland Browns' general manager Monday. The source said the Eagles have interviewed a minority candidate as required by the NFL's Rooney Rule, but declined to identify the candidate.
