Ravens associate head coach and special teams coordinator Jerry Rosburg blamed himself for the defense he called on the Jacksonville Jaguars’ 58-yard fake punt in the third quarter Sunday. Offensive coordinator Marty Mornhinweg said the responsibility lies with him to get the offense playing at a higher level and to get the wide receivers more involved. Defensive coordinator Dean Pees acknowledged that the onus is on him and the other defensive coaches to make sure their unit plays with more intensity.

Coach John Harbaugh’s top three assistants each took turns after Thursday’s practice accepting some of the blame for the team’s woeful performance in a 44-7 loss to the Jaguars.

“I’ll tell you what, this is my responsibility now. I’ve got a little responsibility here and I take that responsibility very, very seriously. What happened that last ballgame, a lot of colorful verbs, right? So now where do we go? We get better every day,” Mornhinweg said after his offense was shut out for the first 56 minutes and Joe Flacco threw for just 28 yards. “Our expectations stay very, very high. And we put the hard work in and we prepare. Everybody needs to step up, and it starts with me. That thing last week, everybody needs to do better, period. That’s how we’re going to handle this thing.”

Mornhinweg said that Ravens’ focus is solely on Sunday’s matchup with the Pittsburgh Steelers, but he acknowledged that the mood of the players has been a little bit sharper, given what happened Sunday in London.

“I think everybody is probably a little different this week after that,” he said. “We can all do better. We went through a deal and we’ve got to rebound this thing. Now. I don’t fluff over anything. I don’t want to dance through the tulips or anything like that. That’s not the case. We’ve got some work to do.”

Despite giving up 410 yards of offense and allowing Blake Bortles to throw four touchdown passes and post a 128.2 quarterback rating, Pees said his defense actually made fewer mistakes against the Jaguars than it did in the first two games versus the Cincinnati Bengals and Cleveland Browns.

“I know one guy wrote that we disappeared on Sunday. Well, on third down, they were three of 12. So evidently, we didn’t disappear on third down. OK, did they have two really good backs? They averaged 3.3 [yards] a carry by those backs. There’s 60 yards of rushing on there that was on a fake punt. They averaged 3.3 yards,” Pees said. “We asked Carl Davis, who hadn’t practiced at five-technique all week, to go out and play five technique for Brent Urban and [for] WillieHenry to go in and play. Those two guys played their butt off. You watch the film, they played their butts off. It wasn’t that we didn’t get them stopped. Here’s what we didn’t do: We didn’t disappear on third down and we didn’t disappear in the running game. It kind of offends me that that comment was made.”

Pees did acknowledge that the defense lacked the intensity that it maintained through the first two weeks.

“The biggest thing for us is the intensity and I’d be shocked if we didn’t have it this week against these guys at home,” Pees said.

No surprise: Alex Collins might have surprised fans by leading the Ravens in average yards per carry at 7.8 on just 16 attempts in one fewer game than starter Terrance West and backup Buck Allen. But the least surprised person is the second-year running back himself.

Asked after Thursday afternoon’s practice whether he anticipated playing as well as he has since being promoted from the practice squad Sept. 16, Collins said: “Anyone in my position would. That would be our intent coming in, and that just how I took it. Every practice is like a game day for me, the way that I prepare. So if I am going into the fire, I know what I’m doing and I’m capable and ready. So that’s just how I looked at it. And then the chips fell, and I got the opportunity, and I was ready for it.”

Collins, a 2016 fifth-round draft pick of the Seattle Seahawks who was signed by the Ravens to their practice squad Sept. 5, has rushed for 124 yards and trails Allen and West by just 28 yards and 4 yards, respectively. West has two touchdowns on the ground while Allen and Collins are still searching for their first. That that has not stopped Collins from aiming to be the featured tailback.

Harbaughsaid what he appreciates most about Collins is, “the fact that he gets yards. He makes tacklers miss, he breaks tackles. I like guys that get yards on their own.”

For now, Collins is still third on the depth chart, but Mornhinweg praised Collins for working diligently under running backs coach Thomas Hammock.

“He’s got a little speed, he’s got a little quickness,” Mornhinweg said. “He’s a good football player, he’s got instincts, all those things. He’s a sharp kid. He puts the hard work in. He prepares well. With hard work and preparation, he can get this thing done pretty well.”

No changes:For the second day in a row, starting nose tackle Brandon Williams was at Ravens practice. But for the second day in a row, he was not participating.

Williams, who missed Sunday’s loss because of a foot injury suffered the week before, stretched, but did little else during the portion of practice open to the media Thursday afternoon.

Tight ends Benjamin Watson (left calf) and Maxx Williams (left ankle) and rookie cornerback Jaylen Hill (hamstring) were absent from practice. None of the three participated in Wednesday’s session.

New anthem performers:The Ravens announced Thursday that a vocal trio from the United States Air Force Heritage of America Band will perform the national anthem before Sunday’s game.

Among the band’s previous anthem performances include the 2015 Preakness, the 2013 World Series and the 2012 NFL Pro Bowl.

The decision comes two days after the team’s anthem singer for the past four years, Joey Odoms, resigned. A combat veteran, Odoms wrote on Instagram that the “tone/actions of a large number of NFL fans in the midst of our country’s cultural crisis, have convinced me that I do not belong” at M&T Bank Stadium.

Odoms later clarified his post, writing, “Fans who attack players for protesting, (a right in which I fought to defend) but are simply not interested in understanding why, is the reason I am resigning.”

Jones to retire a Raven:The team announced Thursday that former return specialist-wide receiver Jacoby Joneswill retire Friday as a Raven. Jones, who scored six touchdowns on kick and punt returns in three years with the organization, will retire during a news conference attended by general manager Ozzie Newsome and Harbaugh.
