Sirmon has had considerable success as the Bears' defensive coordintor the past six years, but now he's headed to the NFL as a linebackers coach

Sources: Cal defensive coordinator Peter Sirmon is leaving to become the linebackers coach for the New Orleans Saints. He spent seven seasons at Cal, the last five as the defensive coordinator.

This was a somewhat surprising hire for the Saints. New defensive coordinator Brandon Staley will have a total of three collegiate position coaches on his staff under head coach Kellen Moore. Only one of those has any coaching experience at the NFL level.
