The Ravens announced Marty Mornhinweg as Trestman's replacement in a subsequent move. Mornhinweg previously served as the team's quarterbacks coach.
"My obligations are to the team, the organization and the fans to be the very best team we can be," coach John Harbaugh said in a statement. "Today we find ourselves one game out of the division and conference lead after experiencing two tough losses at home. We will work to be better in every aspect of our football team. Our expectations are high, and we look forward to fulfilling them."
Harbaugh spoke about the change again during his press conference on Monday, via the team's Twitter account:
On Thursday, Jason Cole of Bleacher Report cited sources that believe Ravens owner Steve Bisciotti had a hand in Trestman's firing:
Baltimore ranks 23rd in yards per game and is averaging just 18.8 points during its 3-2 start. Trestman's play-calling was again under fire after the Ravens attempted 47 passes against 19 rushes despite the run game being far more effective Sunday.
Quarterback Joe Flacco managed just 210 yards on his 46 attempts despite completing 30 passes. None of those passes went for more than 15 yards, and every Ravens pass-catcher averaged less than 10 yards per reception.
"It is frustrating. I'm not happy," Flacco said, per Jamison Hensley of ESPN.com. "It's embarrassing to run off the field in front of your home fans, in front of your teammates. Our defense is putting up awesome plays week after week, and we're just running off the field. It doesn't feel good as a quarterback, the leader of this offense, to do that."
The Ravens' abandonment of the run was curious given their success early on. They produced 76 yards on 12 carries in the first quarter, but Trestman called just seven runs in the final three quarters. Running back Terrance West had 95 yards on 11 carries, and his 35-yard scamper was by far Baltimore's biggest play of the afternoon.
Ian Rapoport of NFL Network offered context on the move:
Wide receiver Breshad Perriman, billed as a downfield threat who hasn't produced a play longer than 20 yards since Week 1, expressed frustration on Twitter:
The Ravens have had trouble keeping offensive coordinators in recent seasons, though the reasoning for their departures has varied. Jim Caldwell and Gary Kubiak parlayed successful turns in Baltimore into head coaching positions. Attacks led by Cam Cameron and Trestman have sputtered to the point that Harbaugh's been forced to make midseason adjustments.
As Jeff Zrebiec of the Baltimore Sun noted, Harbaugh previously replaced Cameron with Caldwell after a loss to Washington. The Ravens went on to a Super Bowl run during that 2012 campaign.
Trestman was in his second season in Baltimore after previously serving as the Chicago Bears head coach. He had a legendary career coaching in the CFL but has not been able to translate his offensive approach stateside.
Mornhinweg previously served as the offensive coordinator for the San Francisco 49ers, Philadelphia Eagles and New York Jets. He was the head coach of the Detroit Lions from 2001-02, posting a 5-27 record before being fired after two seasons.
