OWINGS MILLS, Md. -- Baltimore Ravens coach John Harbaugh answered a question about offensive coordinator Marty Mornhinweg's job security by again professing his faith in the NFL's 30th-ranked offense.

"There's no doubt in my mind that we can be a successful offense throughout the rest of the season," Harbaugh said a day after the Ravens' 23-20 loss to the Tennessee Titans. "We've shown enough flashes of it. Based on the tape, based on the way I see guys playing and who we have and haven't had out there, I feel like we're going to being able to do that. I have a lot of confidence in the coaching staff. I have a lot of confidence in the players. I can see the way forward."

The Ravens failed to score an offensive touchdown for the fifth time this season in Sunday's loss and didn't reach the end zone until there was nine minutes left in the game. Baltimore is averaging 16.5 offensive points per game, which ranks eighth-worst in the NFL.

Harbaugh said there is optimism surrounding the offense with the return of running backs Danny Woodhead (hamstring) and Terrance West (calf). Both will practice this week before players are given four days off for the bye. Woodhead, in particular, provides the biggest matchup problem for defenses and can provide a boost on third downs, which has been a trouble spot for Baltimore.

"I see an identity to this offense," Harbaugh said. "I understand the identity. I understand where we're going as an offense. I have a good feel for what we're trying to accomplish. I can look at it and see where we're going to build. I'm excited about it."

There's been a building frustration with the players after the Ravens were held to 20 points or less for the fifth time this season.

Joe Flacco ranks No. 31 in passer rating (72.7) and has thrown eight touchdowns and 10 interceptions. Wide receiver Jeremy Maclin is averaging a career-worst 11.5 yards per catch, and Mike Wallace is on pace for a career-low receptions total (36).

"We have too many players on our team for us not to be moving the ball," Wallace said after the game. "Whatever we got to do to fix it, we got to do."

Harbaugh has a history of changing offensive coordinators to create a spark. He fired Cam Cameron in December 2012 and parted ways with Marc Trestman in October 2016, and those offenses were statistically better than this year's.

So, what makes Harbaugh believe Mornhinweg is the right play-caller to lead this offense?

"It's a fair question," Harbaugh said. "I think those kind of decisions are always fairly complex. It cuts to the matter of what you're trying to do. Those are tough choices to make."
