So who will sit at the front of the classroom and help JaMarcus Russell's development?
It won't be Greg Knapp, who per Adam Schefter of the NFL Network, has made the long expected move to Seattle to join Jim Mora's staff as offensive coordinator.
Knapp was Mora's offensive coordinator in Atlanta.
Knapp spent two seasons in Oakland and was one of three employees Al Davis spoke with before deciding to go with Tom Cable as interim head coach.
Knapp was stripped of playcalling duties he inherited after Lane Kiffin was fired following the Raiders' 24-0 loss to Atlanta, but continued to run quarterback meetings and work closely with Russell.
Davis is said to want to move quickly in hiring a head coach, but while every other team with an opening has been interviewing candidates, the Raiders have yet to bring in anyone.
A phone call with New York Giants offensive coordinator Kevin Gilbride (which the Raiders aren't calling an interview) is all the team has done since the end of the season.
Schefter reports the Raiders staff has several coaches that could leave as their contracts expire and the Raiders have no head coach in place.
Special teams coach Brian Schneider is sure to have suitors. Defensive coordinator Rob Ryan has maintained he'd have no problem finding another job if not retained by the Raiders. And if his twin brother Rex Ryan were hired to be a head coach, Rob would definitely have at least one place to go.
Eric Mangini has reportedly accepted the head job in Cleveland and he might be inclined to bring Ryan on as his defensive coordinator.
Ann Killion, in her column yesterday in the San Jose Mercury News, touched on the possibility of Raiders running backs coach Tom Rathman returning the to the 49ers.
So it looks as if Cable does return, he'll have to rebuild his staff, too.
