OWINGS MILLS, Md. -- A month after "going Trump" in training camp, coach John Harbaugh tapped into Winston Churchill for some motivating words for the winless Baltimore Ravens.

"What's the old saying, 'When you're going through hell, keep going,'" Harbaugh said Monday, a day after the Ravens fell to the Cincinnati Bengals, 28-24. "That's what we're going to do. We're going to keep going. We're going to find a way out. We will come out of this the other way."

The Ravens are one of four winless teams in the NFL, joining the Detroit Lions, New Orleans Saints and Chicago Bears. The Saints and Bears, however, are without their starting quarterbacks.

This marks the first time the Ravens are 0-3 in their 20-year existence, but Baltimore has had three previous three-game losing streaks under Harbaugh (2008, 2009, 2013). The Ravens made the playoffs in 2008 and 2009.

But there are no easy fixes for Baltimore. Injuries have taken away the Ravens' fastest player on offense (first-round pick Breshad Perriman) and their emotional leader on defense (linebacker Terrell Suggs).

On offense, the Ravens have the 27th-ranked rushing attack and only one proven playmaker (wide receiver Steve Smith Sr.). On defense, over the last two weeks, Baltimore has allowed the fourth-most points (65) and the second-most passing yards (723).

In comparison, the Ravens didn't lose their third game last season until Oct. 26.

"We're a very confident football team and we feel like we can overcome any adversity," Harbaugh said. "We have before and we will again."

Since the NFL expanded to its current 12-team playoff format in 1990, only three teams have started 0-3 and reached the playoffs: 1992 San Diego Chargers, 1995 Detroit Lions and 1998 Buffalo Bills.

But the Ravens, who play at rival Pittsburgh on Thursday, believe they can turn their season around because they've lost their three games by a combined 14 points. That's a similarity to the 1998 Bills (who lost their first three games by nine points) and the 1995 Lions (16 points).

"We've been in a whisker, a play of winning all three of these games," Harbaugh said. "That doesn't count for a hill of beans when it's all said and done when you look back. But it does count for something going forward. We understand what kind of football team we're capable of becoming."
