Ravens are far from done with free agency

PHOENIX -- The Baltimore Ravens are known for signing free agents after the first wave is complete, and the team could follow a similar path this offseason.

At the NFL owners meetings Monday, coach John Harbaugh indicated the Ravens intend to be active in free agency. The biggest positions of need remain wide receiver, tight end, cornerback and backup quarterback.

"We're just staying on top of it every second," Harbaugh said. "It's not like we're sitting back and just relaxing. We're monitoring it and we're talking to guys and agents. We want to be proactive."

Through the first two weeks of free agency, the Ravens have re-signed six of their own free agents, but they've only added one free agent from another team: safety Kendrick Lewis. Their current salary-cap space is $8.3 million after restructuring cornerback Lardarius Webb's contract.

The Ravens have yet to replace wide receiver Torrey Smith (49ers), tight end Owen Daniels (Broncos) and backup quarterback Tyrod Taylor (Bills), all of whom left for bigger paydays elsewhere.

Here are the top available free agents at the Ravens' positions of need:

Wide receiver: Michael Crabtree, Greg Jennings, Denarius Moore and Hakeem Nicks.

Tight end: Jermaine Gresham (injured), Rob Housler, Zach Miller and James Casey.

Cornerback: Alan Ball, Tarell Brown, Kyle Wilson and Josh Wilson.

Quarterback: Jason Campbell, Tarvaris Jackson, Michael Vick and Matt Schaub.

The Ravens' history is to sign free agents later into free agency because they get the best value that way. They did it last year when they brought in running back Justin Forsett and Daniels on April 3.

"The more that you can add before the draft, it takes pressure off the draft to chase a position," Harbaugh said. "The more we can do that, the better off we'll be."
