ALAMEDA -- Lane Kiffin admitted Monday that he miscalculated the strength of the Oakland Raiders defense, which is one reason why Rob Ryan will be officially out as defensive coordinator sometime this week, free to accept the same position with the New York Jets.
Sources indicate Ryan was told before the Raiders' final game, against San Diego on Sunday, that he would not be returning in 2008 and had already secured his next place of employment, hardly a surprise but still somewhat remarkable in that just 12 months ago, Ryan received more than just cursory consideration for the head job Kiffin got.

How about switching Ryan's, apparently Rex was fired with the rest of the Raven staff. Billick was fired Monday, less than 24 hours after his team concluded a season of high expectations with a disappointing 5-11 record. His entire staff, including defensive coordinator Rex Ryan, also was dismissed. http://sports.espn.go.com/nfl/news/story?id=3175037
