The Ravens aren't making any changes at either coordinator position this offseason following a 5-11 campaign.
Head Coach John Harbaugh told reporters Thursday that Defensive Coordinator Dean Pees and Offensive Coordinator Marc Trestman will both be back for 2016.
The only change, as of now, is Linebackers Coach Ted Monachino has left to become the defensive coordinator of the Indianapolis Colts.
It will be the first time since the 2009-2010 seasons that the Ravens have the same offensive and defensive coordinators in consecutive years.
"No changes to the coaching staff," Harbaugh said. "Certainly changes in how we do things, and how we approach things, and schemes and things like that. We're going to work on that already. But the same guys will be in place and I'm excited to work with our guys."
There has been radio and internet chatter about the possibility of Pees moving on, but Harbaugh said he doesn't listen to that.
"I know what kind of coach Dean Pees is," Harbaugh said. "I look at the season and the improvements that we made, especially on the back end, throughout the course of the season, and that's what you look for."
The Ravens secondary struggled with giving up big plays for the first half of the season. It directly led to losses against the Oakland Raiders, Cincinnati Bengals, Cleveland Browns and Arizona Cardinals.
But over the second half of the season, the Ravens were the second-best overall defense in the league and the best pass defense.
The Ravens gave up a paltry 182.6 passing yards per game over their final eight games. They improved by more than 100 passing yards per game (283.9 over the first half).
Baltimore finished the year eighth in total defense (337.4 yards) and 24th in points per game (25.1).
"I thought we were up and down and inconsistent throughout the first eight games of the season, for sure," Harbaugh said. "We went to battle and went to work to correct those things and found a way to correct most of them throughout the course of the season."
The Ravens began blitzing their linebackers less and playing more zone defense. When playing man-to-man defense, they told cornerbacks to simply shadow their man in order to keep eyes in the right place. Harbaugh referred to it as "minding your luggage." Baltimore still struggled to create turnovers, but it at least stopped giving up so many big plays.
"We have plenty of work to do, but I trust Dean and know he's a very good coach," Harbaugh said. "All those guys are very good coaches. When you work side-by-side with a bunch of guys through a season like this, you find out what they're made of. And I like our guys."
In his first year, Trestman engineered an offense that finished 14th in the NFL with 359.3 yards per game. The Ravens were 25th in points per game (20.5).
Baltimore finished with the second-most net yards in team history, 90 yards short of the record set last year under now Broncos Head Coach Gary Kubiak.
Despite not having starting quarterback Joe Flacco for the final six games, and using four different starters over the course of the season, the Ravens set a new franchise record for passing yards in a single season (4,271 yards).
