The Ravens secondary was considered by pundits to be the team's weakness last season.
Baltimore has Matt Elam returning, but Darian Stewart and Jeromy Miles are unrestricted free agents, Will Hill is a restricted free agent and sophomore Terrence Brooks is coming off knee surgery.
The Ravens could look to free agency to strengthen the group, but there aren't a lot of great options.
Here's a look at who's out there (barring they sign with their current teams before free agency opens on March 10):
Devin McCourty, New England Patriots
Unrestricted; 27 years old; 5-foot-10, 195 pounds
2014 Stats: 68 tackles, 6 passes defensed, 2 interceptions
McCourty made the transition from cornerback early in his career and has flourished as a safety. He's started every game but three over his five-year career and is a sure tackler with ball skills. McCourty picked off quarterback Joe Flacco in the AFC divisional round. He's also known for his work in the community off the field.
Dawan Landry, New York Jets
Unrestricted; 32 years old; 6-foot-1, 212 pounds
2014 Stats: 107 tackles, 1.5 sacks, 1 passes defensed
The Ravens know Landry well as they originally drafted him and Landry spent five years in Baltimore (2006 to 2010). Like many homegrown products, Landry eventually bolted for a bigger payday in Jacksonville, then reunited with former Ravens Defensive Coordinator Rex Ryan in New York. He's on the market once again, and, despite his age, is still playing at a high level. He was the ninth-best safety in the league last year, according to Pro Football Focus. That's just one spot behind McCourty.
LaRon Landry, Indianapolis Colts
Unrestricted; 30 years old; 6-foot-0, 226 pounds
2014 Stats: 47 tackles, 2.5 sacks, 0 passes defensed
The younger brother of Dawan Landry, LaRon has made a name for himself, as well. He was the bigger prospect coming out of college, but has bounced between the Redskins, Jets and Colts the past four seasons. Landry was suspended four games last year for a performance enhancing drugs violation. Also due to injuries, he hasn't played more than 12 games in four of the past five years. But if healthy and out of trouble, he's a ferocious hitter who brings energy to the back end.
Louis Delmas, Miami Dolphins
Unrestricted; 27 years old; 5-foot-11, 210 pounds
2014 Stats: 51 tackles, 1 sack, 3 passes defensed, 1 interception
Delmas was a hot commodity coming out of college, and he was the first pick in the second round in 2009. Delmas is a big hitter with a lot of natural tools and speed. He hasn't been very consistent over his career, however. He signed a one-year deal with the Dolphins last offseason after five years with the Lions, and missed three games because of injuries and rated as the 51st best safety, per PFF. He still has a lot of potential, however.
Antrel Rolle, New York Giants
Unrestricted; 32 years old; 6-foot-0, 206 pounds
2014 Stats: 87 tackles, 9 passes defenses, 3 interceptions
In mid-February, the Ravens' Hill posted on Instagram saying he wanted to reunite with Rolle, as they played side-by-side in the Giants secondary. Rolle is a talented player who went to the Pro Bowl in 2009, 2010 and 2013, but he had a down year last season and is getting aging. Rolle ranked 81st out of 87 safeties by PFF. That's what makes him a bargain, and perhaps a change of scenery would help.
Nate Allen, Philadelphia Eagles
Unrestricted; 27 years old; 6-foot-1, 210 pounds
2014 Stats: 62 tackles, 1 sack, five passes defensed, 4 interceptions
Allen is a fierce competitor who has been a steady performer during his five years in Philadelphia. Allen is a big hitter who also shows some ball skills with a career-high four interceptions. Allen has run into some legal trouble with allegations of indecent exposure, but the State Attorney's Office in Florida released a statement clearing Allen of any wrongdoing.
