Ravens, Steelers, Browns, Bengals: Free agency signings around the AFC North

This is the time of the year where NFL teams make a push to add a missing piece or two (or three) to the mix to improve upon the previous season.

Some teams take an aggressive approach. Others play it more subdued. The Ravens, in particular, like to lock up the guys they want to keep from the previous season's roster before hitting the market.

Each team is different in its approach to rebuilding a roster, naturally.

That stated, here's a look at how the AFC North has shaped out in free agency thus far:

Baltimore Ravens

Re-signed: WR Jacoby Jones, OT Eugene Monroe, TE Dennis Pitta

New arrivals: None yet

Leaving: CB Corey Graham (Bills), DE Arthur Jones (Colts)

Remaining free agents: TE Dallas Clark, DT Terrence Cody, TE Ed Dickson, S James Ihedigbo, S Jeromy Miles, OT Michael Oher, RB Bernard Scott, ILB Daryl Smith

Analysis: The Ravens locked up their top two priorities in Pitta and Monroe. Jones was also high on the list of guys to bring back. The Ravens will likely hit the receiver market in the coming days for either Steve Smith or Julian Edelman, or perhaps both if it works in their budget. But before looking at other positions, the Ravens may want to see what they can get done with Oher and Smith first.

Cleveland Browns

Re-signed: K Billy Cundiff

New arrivals: ILB Karlos Dansby, DB Isaiah Trufant, SS Donte Whitner

Leaving: ILB D'Qwell Jackson (Colts), OG Shawn Lauvao (Redskins), SS T.J. Ward (Broncos)

Remaining free agents: OG Oniel Cousins, LB Paul Hazel, RB Willis McGahee, WR Brian Tyms, OT Martin Wallace

Analysis: The Browns did a good job replacing Jackson and Ward with Dansby and Whitner. Dansby is an upgrade, though Whitner and Ward are probably equals. The Browns just missed on Darrelle Revis, which would have immediately made that defensive backfield the best in the NFL. But it's the Browns. Good things aren't allowed to happen to them (or so they say).

Cincinnati Bengals

Re-signed: WR Brandon Tate

New arrivals: None yet

Leaving: OT Anthony Collins (Buccaneers), DE Michael Johnson (Buccaneers)

Remaining free agents: LB Michael Boley, DB Chris Crocker, DB Brandon Ghee, FS Taylor Mays, P Zoltan Mesko, OG Mike Pollak, OT Dennis Roland, TE Alex Smith

Analysis: The Bengals lost two quality players, though they wouldn't have been able to afford them. However, their team is still loaded, especially on offense outside of quarterback. But maybe with another year of experience, Andy Dalton can show he's the franchise quarterback the Bengals thought he'd be. The Bengals do have plenty of cap space to make a splash at some point.

Pittsburgh Steelers

Re-signed: SS Will Allen, C Cody Wallace, LS Greg Warren, OLB Jason Worilds

New arrivals: FS Mike Mitchell

Leaving: RB Jonathan Dwyer (Cardinals), DE Ziggy Hood (Jaguars), TE David Johnson (Chargers), NT Al Woods (Titans)

Remaining free agents: OT Levi Brown, WR Plaxico Burress, OT Rashad Butler, FS Ryan Clark, WR Jerricho Cotchery, RB Felix Jones, DE Brett Keisel, P Mat McBriar, TE Michael Palmer, WR Emmanuel Sanders, RB LaRod Stephens-Howling, LB Stevenson Sylvester, C Fernando Velasco, LB Jamaal Westerman, OG Guy Whimper, OLB LaMarr Woodley

Analysis: The Steelers have a lot of work to do this offseason judging by all of the free agents hitting the market. Mitchell is a decent replacement for Clark, who isn't expected to return to Pittsburgh. This could be an offseason where the Steelers look to re-built their offensive line, which couldn't garner any kind of push (except against Baltimore for whatever reason) in 2013.
