The Ravens now have to make another replacement in the higher ranks of the organization, but this one has nothing to do with coaching.
Former Baltimore director of pro personnel George Kokinis was officially named general manager of the Cleveland Browns late Sunday after days of speculation and multiple interviews.
Kokinis takes over for departing general manager Phil Savage, under whom Kokinis had worked with the Ravens.
Mangini and Kokinis' relationship goes back many years. Mangini's career in the NFL began with the Browns as a ballboy and public relations intern in 1994, while Kokinis was moving up the ranks as a scout.
The duo even shared a small apartment with current Kansas City Chiefs general manager Scott Pioli for part of that year.
Pioli, who recently left a similar position with the New England Patriots, was actually the first candidate Browns owner Randy Lerner interviewed, but he decided to join the Chiefs.
Kokinis, 41, has been widely regarded as a rising star in the personnel business. Coming to Baltimore when the club moved from Ohio in 1996, Kokinis became the director of pro personnel in 2003.
He was a major reason why the Ravens were able to persevere through multiple injuries to key players this year en route to their 13-6 record, as depth was one of Baltimore's strengths.
Assistant director of pro personnel Vince Newsome, who has been in the franchise' front office since 1993, is one name that could replace Kokinis. Another scenario is expanding the responsibilities of director of college scouting Eric DeCosta. Ozzie Newsome heads the Ravens' personnel department as executive vice president and general manager.
Meanwhile, Harbaugh is expected to name his new defensive coordinator to replace Rex Ryan early this week. Ryan recently accepted a position as head coach of the New York Jets.
