The Baltimore Ravens have experienced some unexpected shake ups within their coaching staff over the past few weeks, and have now officially announced they've stabilized their back-end braintrust in accordance with a few of those losses.

This puts an end to the search for a replacement of Leslie Frazier, who departed in a somewhat surprising move to join Sean McDermott’s new staff in Buffalo.

A few other moves were made that rounded out their defensive front end on the coaching side, as well as their strength and conditioning program.

Finally, they announced Marty Morninwheg, who was retained as offensive coordinator, will still play the role heading into the 2016 season.

None of these moves are particularly splashy or shocking, save for the continued presence of Mornhinweg, but that has been known about for some time now.

While there are no huge names to report on this list, the focus on continuity and hiring from within is reason for potential optimism, as it maybe goes against the impatient grain of the modern NFL.

As for how these changes will affect the team, the only way to know is to wait and see how they perform on the field in 2017.
