Green Bay Packers coach Mike McCarthy filled out the last key position on his staff Saturday, promoting defensive ends coach Bob Sanders to defensive coordinator. Sanders will replace Jim Bates, who announced last week he wouldn't return to the team after he was passed over for the head coaching job. McCarthy said he tapped Sanders, a coaching veteran of 30 seasons who was with the Packers for only one, after a week of interviews. "I was impressed with Bob's football knowledge, and, equally, with him as a person and his character," said McCarthy, who was hired Jan. 12 to replace Mike Sherman. "I felt like this is someone I could have a partnership with and who I would have great confidence in to run our defense."
