Mark Andrews has heard enough. The question now is if his irritation will make any difference.

The Ravens tight end is typically concise and steely when talking with the media, being careful not to say too much. On Tuesday, he again didn’t speak for very long — two minutes — but he let loose, firing back at criticism the Ravens, and their sputtering offense in particular, has faced recently.

The negative commentary around the team, still squarely in the playoff hunt, showed up literally at the Ravens’ front door over the weekend in the form of “Fire Greg Roman” messages calling for the offensive coordinator’s removal. They were written in black marker on five pieces of notebook paper and left by someone outside the team’s headquarters in Owings Mills in the hours after its 13-3 loss at the Cleveland Browns.

“I know there’s a lot of outside noise,” Andrews said, speaking to reporters to begin his defiant rant. “For us, it’s coming in here and working. ... There are a lot of hungry people in this building. We have an incredible team. We have coaches that really want to win, that are doing everything they can. This is an inspired group.”

To hear Andrews — the team’s leader in receiving yards (702) and touchdowns (5) — they’re not just inspired, but angry, too, ahead of Saturday’s Christmas Eve tilt, scheduled for 1 p.m. against the visiting Atlanta Falcons (5-9).

Despite all the noise — and the absence of their primary offensive engine — the Ravens (9-5) actually still have a chance to clinch a playoff berth with a win.

“We’re going to bring it every game no matter what,” he said, “and that’s all I can say about that.”

Asked if the team would rally around criticism to prove people wrong, Andrews said: “I don’t give a shit, to be honest. I don’t give a shit. If someone wants to take that and use it as fuel, that’s fine. I have a chip on my shoulder either way.”

After an ugly loss in Cleveland that took control of the AFC North out of the Ravens’ hands, though, the question now is if the right attitude — however edgy it may be — can help the Ravens win enough games down the stretch to take the division, and host a playoff game, and/or make the postseason at all.

Because the challenges keep mounting.

The defense has been on a heater since its late-game breakdown in a 28-27 loss to the Jacksonville Jaguars. But the Ravens offense — led mostly by backup quarterback Tyler Huntley — has scored only two touchdowns in the last three games, and has had plenty of problems in the red zone. It frequently had issues simply getting plays called on time, even before Jackson was injured.

Fans are not frustrated without cause. The problems are plain to see.

Jackson’s status is in doubt ahead of the Falcons game. Out with a reported PCL strain in his left knee, Jackson hasn’t practiced since before he was hurt Dec. 4 against the Denver Broncos. Ravens coach John Harbaugh this week has been mum on Jackson’s availability, citing competitiveness reasons, though it looks like he won’t play for the third straight game after not practicing Tuesday or Wednesday.

And injuries keep piling up. Defensive back Marcus Peters (calf) and veteran defensive lineman Calais Campbell (knee), injured in the second half against the Browns, haven’t practiced the past two days. And the latest setback for the offense is a foot injury to wide receiver, kick and punt returner, and frequent jet-sweeper Devin Duvernay, who got hurt Tuesday in practice and was put on injured reserve, at least ending his regular season.

In an effort to help replace Duvernay, the Ravens signed veteran Sammy Watkins, who was with the team a year ago, off waivers from the Green Bay Packers. But Watkins isn’t likely to make a meaningful difference to a passing game that has mustered only 220 yards in the last two games with Huntley behind center, and hasn’t seen a wideout catch a touchdown pass since Week 3. Even Huntley appears to be dealing with an injury: He was limited in practice Wednesday with an injury in his throwing shoulder.

Andrews, by far the team’s most threatening pass-catcher, is constantly double-teamed, something Roman talked about two weeks ago, and at other times has been open on long developing pass plays but not found in coverage.

Still, the Ravens had won six of their last seven before last week. And the offense had gotten by lately in wins over the Carolina Panthers, Broncos and Pittsburgh Steelers, powered by a ground game increasingly led by a rejuvenated J.K. Dobbins, who has 245 rushing yards in the past two games.

But Dobbins’ 125-yard effort on 13 runs — and Gus Edwards’ 55 yards on seven carries — were spoiled Saturday night by a plethora of mistakes that cost the Ravens the division lead and dropped them to the top spot in a competitive AFC wild card race.

One of the issues might have been the play-calling itself. Dobbins didn’t touch the ball in the fourth quarter. The Ravens were trying to score quickly, down 10 points early in the fourth quarter, but only ran the ball once in the final 15 minutes and not at all in the final 11 minutes, despite averaging more than seven yards per carry.

Harbaugh admitted Monday in a press conference, “We could have done some runs at that point.”

On Wednesday, Roman addressed the idea, too, of not running the ball on the Ravens’ second-to-last drive in particular. “We were down two scores and we got into a different mode,” Roman said. “You can go back and second-guess that all you want. ... We got more into a hurry-up mode, tried to change the tempo of things.

“We were moving it really well on the ground for sure. … Could we have stayed into that mode more? Probably. You look back and you’re like, ‘Jeez. We could have kept going with that a little bit more.’ But on Monday, it’s always easy to say that.”

Frustrations around the offense aren’t new among swaths of the Ravens fanbase. Calls for Roman’s departure date to at least last season. Instead, defensive coordinator Don “Wink” Martindale was replaced in the offseason.

But the drumbeats for change on offense might be louder than ever. The papers dropped outside the Ravens facility are surely the most visible sign of that.

Outside linebacker Tyus Bowser said he came across them Saturday night when he showed up to the facility after the team’s flight back from Cleveland.

“Well, alright then,” he uttered and wrote in a caption on a short Instagram story, where he showed the pieces of looseleaf paper calling for Roman to lose his job. He was more surprised than anything, Bowser said, and posted the clip on social media.

That turned out to be a mistake, as it made clear the team has heard the complaints about its sputtering offense of late and began speculation on the source of the papers. The Ravens’ headquarters is hardly an impenetrable fortress; a disgruntled fan could have walked up and left them. However, there are cameras everywhere.

If he knows, Harbaugh declined to reveal the source of the complaints, saying Monday, “I don’t care how they got there. I don’t care. I’m not security. Security has got to worry about that. It’s paper — paper.”

Bowser said he apologized to Roman in person on Sunday morning for the post, which he later deleted. Roman said after talking with Bowser he chalked the post up to a “misunderstanding that people in the arena probably laugh about.”

“I think his intentions were misinterpreted,” Roman said. “We had a great discussion. We had a great handshake and hug.”

Still, despite the mounting issues and public criticisms, the Ravens can make the playoffs with a win and some help this weekend. The Falcons, though, rank third in the NFL in rushing yards per game with 164, though they became less experienced lately with former starting quarterback Marcus Mariota going on injured reserve. Rookie Desmond Ridder (a third-round pick out of Cincinnati) is the Falcons’ new signal-caller and will make his second career start.

There are 10 scenarios in play in which the Ravens can clinch a playoff berth:

So making the playoffs still looks like a good bet for the Ravens, which might be all that should be expected with Jackson sidelined.

But the Ravens still want to win their division, and to do that they’ll likely have to beat the Bengals for a second time this season on the road in their season finale Jan. 8. And unless the Bengals drop a game or two of their own down the stretch, the Ravens will also have to win out, starting Saturday against the Falcons and again on New Year’s Day in a rematch with the Steelers.

“Everything that we want, everything that we can do is still ahead of us,” Andrews said. “There’s no like, ‘Poor me.’ There’s none of that in this building. That’s all outside noise. We’re fired up. We’re going to be ready to go. Everything’s in front of us, so be ready.”

Roman: It’s not the critic who counts

Here’s more from Roman on how he handles criticism as an offensive coordinator: “I’m a fan. I sit in the stands at Orioles games and whatnot. I know what it’s like to be a fan. You love the passion, you love the emotion. … That’s a great thing.

“But it’s two different worlds. That world of the fan is the fan, and then there’s the people in the arena — the players, the coaches, etc. The first thing you’re told when you get into this profession is don’t listen to any of the noise. … It comes with the job.

“In the arena, you have to laser-beam focus on the task at hand. You can’t let anything distract you from that. … How the offense performs, that’s what I’m concerned about.”

He was asked if it’s hard not to take the criticism personally.

“I don’t listen to it at all,” Roman said. “It doesn’t move me at all.”

It’s going to be cold

Whatever happens Saturday, the conditions at M&T Bank Stadium will be frigid. Temperatures are forecast in the low 20s and strong winds could make it feel as low as 2 degrees.
