The Ravens haven't made many waves in the free-agency pool, but they're still swimming in it.
Head Coach John Harbaugh indicated that Baltimore is interested in adding pieces at multiple positions, including wide receiver, tight end, running back and quarterback.
"We're staying on top of [free agency] every second," Harbaugh said at Tuesday's NFL Owners Meetings.
"It's not like we're sitting back and relaxing. We're monitoring it and we're talking to guys' agents. We want to be proactive."
The Ravens still have salary-cap space to make some moves following the trade of defensive tackle Haloti Ngata and the restructuring of cornerback Lardarius Webb and outside linebacker Terrell Suggs' contracts.
Thus far, the Ravens have mostly been focused on retaining their own free agents. They re-signed unrestricted free-agent running back Justin Forsett, defensive end Chris Canty, defensive lineman Christo Bilukidi, defensive lineman Lawrence Guy and long snapper Morgan Cox.
The only free agent they've brought in from outside is safety Kendrick Lewis.
Harbaugh indicated that he would like to solidify some of the team's need positions before April's draft. The Ravens seemingly need the most help at wide receiver and tight end after the departures of Torrey Smith and Owen Daniels.
Harbaugh was asked how important it is to make some "meaningful" additions before the draft.
"It would be really helpful for us to do that," Harbaugh said. "Obviously, the more you can add before the draft, it takes pressure off of the draft to chase a position need. The more we can do that, obviously, the better off we'll be."
Harbaugh said the team would be interested in a wide receiver "if it's the right guy," and still sees talent available on the market at receiver and tight end.
Despite re-signing Forsett, Harbaugh said the Ravens don't have enough running backs. With the release of Bernard Pierce, the only backups on the roster are Lorenzo Taliaferro and Tauren Poole.
"We need more running backs," Harbaugh said, adding that it could come via free agency.
Quarterback is a position where the Ravens could look for a veteran as opposed to adding more youth via the draft. Baltimore selected Keith Wenning in the sixth round last year, and he showed potential while also having typical rookie struggles.
"I want the best guy, the best players we can get," Harbaugh said. "Keith Wenning's got a good future. I like Keith. But we're looking to upgrade everywhere at all times."
