With a deep and versatile secondary, the Ravens didn't expect pass defense to be a problem.

Instead, Baltimore has yielded more passing yards than any team in the NFL – 257 yards per game heading into Sunday's matchup against the Dallas Cowboys. Rashee Rice and Davante Adams have both had 100-yard games against the Ravens, and on Sunday they will face CeeDee Lamb, who's had three straight 1,000-yard seasons, including 1,749 yards last season.

Veteran safety Eddie Jackson started 0-4 with the Chicago Bears last season, and he's not looking to relive that experience with the Ravens, who are 0-2. Jackson remains confident the Ravens have an elite secondary, but the urgency to find solutions has arrived.

"Coming from Chicago to here, you feel the winning culture that's been built," Jackson said. "Guys are like, 'We've got to turn this thing around.' We've got guys in the locker room and coaches who really care. No, this is not OK. We need to go out and get this next win.

"We've got everything we need on this defense. But we've had some miscommunication, guys not lined up in the right spots. We just have to finish."

Gardner Minshew (30-of-38, 276 yards, one TD) had his way against Baltimore in Week 2 as the Las Vegas Raiders overcame a 10-point fourth-quarter deficit to win, 26-23. There were a couple terrific catches by Adams, but there were also times when he and tight end Brock Bowers (nine catches, 98 yards) found open spaces.

This isn't the way the defense expected to start. Not all of Baltimore's issues fall on the secondary, but the pass rush made its presence felt by sacking Minshew five times. Yet according to Pro Football Focus, Kyle Hamilton allowed seven catches in coverage against the Raiders, Marlon Humphrey allowed six, and Brandon Stephens allowed five.

The Ravens have talented and prideful players who expect more of themselves, and they're determined to put their best foot forward in Dallas.

"Just fixing the little details," Stephens said. "There's definitely things we can do better, like closing out games. It's something that's got to get fixed. It's [a] next game mentality. We can't change what happened, but we can improve. We're not backing away from anything. We know who we are, it's just a matter of proving it."

Hamilton took the blame for a coverage mistake in Week 1 that left Chiefs receiver Xavier Worthy wide open for an easy touchdown. The mental mistakes in coverage need to be kept to a minimum for the Ravens' secondary to become more consistent.

"We've had a couple of times we didn't play the defense right," Head Coach John Harbaugh said. "One was a 10-yard gain, and the other one was a touchdown two weeks ago. The other stuff is finishing plays, being in good position relative to the receiver, getting guys on the ground – things like that. We'll keep working on that stuff. Those are all correctable things."

Hamilton (back) and rookie cornerback Nate Wiggins (neck/concussion), who did not play against the Raiders, both didn't practice on Wednesday. The Ravens have been without valuable slot corner Arthur Maulet (knee) all season. However, Stephens is coming off his best season, Humphrey is a three-time Pro Bowler, and Marcus Williams is an instinctive ballhawk who covers as much ground as any safety.

Talent is not the issue, nor is confidence. Williams made that clear when asked about the Ravens starting 0-2.

"I don't even know what our record is," Williams said. "I just know we need to go out and get a victory. Nobody ever likes losing. But at the end of the day, you've got to have short-term memory and do your job."

Looking at the statistics and the standings is more than enough motivation for the Ravens' secondary. Jackson hopes their anger brings out the secondary's best against Dallas.

"Of course you're pissed," Jackson said. "You go out, you put in all this work and you lose? We know what type of team we have, we know what type of talent we have. For us to be 0-2 doesn't show the type of team we are. We have to get this thing turned around and do it fast."
