Reports are starting to surface that the Vikings have, as expected, officially parted ways with defensive line coach Karl Dunbar.

Some may find it funny that Dunbar, a fairly longstanding and respected member of the coaching staff, is being fired after one of his key players nearly broke the single season sack record.

The problem Leslie Frazier has with Dunbar may never be made public, but there are a few things to point towards when wondering why this has happened.

First, in May, Dunbar was charged with sexual assault and he received a restraining order as a result of the woman’s complaints.  That type of thing will never sit well with an organization trying to maintain a positive public image.

Secondly, I found it interesting that Jared Allen recently came out and enthusiastically defended defensive coordinator Fred Pagac but never said a word (that I heard or read, anyways) about what a great job Dunbar, his position coach, had been doing.  Allen is seemingly willing to fight tooth and nail for Pagac, which makes his silence on Dunbar even more telling.

Dunbar is likely the first of multiple coaching changes to be made on defense.

Pagac may or may not stay in his current role and may even be bound to leave the team all together.  We already passed along the fact that the Vikings are talking to Raheem Morris about a role on the defense.

Another interesting thing to throw into all of that, Larry Fitzgerald Sr. is a fairly connected guy within the Minnesota sports community, and he is under the impression that Mike Singletary will be the next defensive coordinator of your Minnesota Vikings.
