Cincinnati Bengals

Key additions: RB BenJarvus Green-Ellis, S Reggie Nelson, G Travelle Wharton, CB Jason Allen, CB Adam Jones, DE Jamaal Anderson, DE Derrick Harvey

Key losses: DE Frostee Rucker (Browns), G Nate Livings (Cowboys), G Mike McGlynn (Colts), DE Jonathan Fanene (Patriots), WR Andre Caldwell (Broncos)

Grade after first wave of free agency: B. The Bengals were the most active team in the division and they should have been. Cincinnati entered free agency with more than $50 million in salary-cap space, which was more than the rest of the AFC North combined. The Bengals upgraded at running back and left guard while bringing back their top free-agent priority in safety Reggie Nelson. The biggest knock against the Bengals is they didn't make a splash by signing a high-profile free agent like guard Ben Grubbs or wide receiver Robert Meachem.

The prize of the Bengals' signings is running back BenJarvus Green-Ellis, who is an improvement over Cedric Benson. Green-Ellis isn't known for breaking long gains, but he is a force in the red zone and has never fumbled in the NFL. Wharton is a step up from Nate Livings at left guard because he is a strong run-blocker who will open holes inside. The biggest losses came on the defensive line, where Cincinnati will miss Frostee Rucker on run defense and Jonathan Fanene in the pass rush.

What’s next: The Bengals can still close the gap between the Ravens and Steelers because they have two first-round picks in the draft (No. 17 overall, which came from Oakland in the Carson Palmer trade, and No. 21). Even with the signing of Wharton, Cincinnati needs a right guard and could have a shot at the top interior offensive lineman coming out of college. Stanford's David DeCastro is one of the safest picks in the draft and would start immediately for the Bengals.

The second first-round pick could be used on a wide receiver or a cornerback. The Bengals surprisingly didn't add a free-agent wide receiver to pair with A.J. Green. Georgia Tech's Stephen Hill or Baylor's Kendall Wright should be available in the bottom third of the draft. Another need is cornerback because Cincinnati could use an eventual replacement for Nate Clements, who is entering his 12th season. Alabama's Dre Kirkpatrick, the second best corner in the draft, has a chance of sliding to the Bengals.

Cleveland Browns

Key additions: DE Frostee Rucker, LB D'Qwell Jackson, CB Dimitri Patterson, DE Juqua Parker

Key losses: RB Peyton Hillis (Chiefs), S Mike Adams (Broncos), G Eric Steinbach, OT Tony Pashos

Grade after first wave of free agency: C. Browns president Mike Holmgren and general manager Tom Heckert said they were building this team through the draft and they weren't joking. The Browns desperately needed to improve at quarterback, wide receiver and right tackle. But Cleveland's offense came out of the initial wave of free agency empty-handed. Blame the Washington Redskins. The Browns attempted to move up in the draft to take Robert Griffin III, and the Rams instead traded the second overall pick to the Redskins. Cleveland reportedly pursued wide receivers Pierre Garcon and Josh Morgan, and both took high-priced deals from Washington.

The Browns provided more help to the defense in free agency. Frostee Rucker will make an impact in stopping the run, which was the biggest weakness on the NFL's 10th-ranked defense. Juqua Parker, who has 31.5 sacks over the past six seasons, will team with Jabaal Sheard to give Cleveland a strong rush coming off both edges. The Browns didn't try to keep Peyton Hillis and Mike Adams from going elsewhere.

What’s next: Offense, offense and offense. Did I mention offense? The Browns need a quarterback but there's no one worthy of the fourth overall pick. Cleveland could trade down to select Texas A&M's Ryan Tannehill or wait until the second round for Oklahoma State's Brandon Weeden. The big decision comes if the Browns stay put at No. 4. Cleveland's choices are Alabama running back Trent Richardson or Oklahoma State wide receiver Justin Blackmon. The Browns could use either one because they don't have a starting running back or a No. 1 wide receiver.

Cleveland has a second first-round pick as a result of last year's trade with the Atlanta Falcons. The Browns need to target a wide receiver (if they don't take one earlier in the first round), right tackle or outside linebacker with the 22nd overall pick. Baylor receiver Wright, Mississippi offensive tackle Bobby Massie and Nebraska outside linebacker Lavonte David have been linked to Cleveland.

Baltimore Ravens

Key additions: C Matt Birk, ILB Jameel McClain, OLB Brendon Ayanbadejo, CB Corey Graham, S Sean Considine

Key losses: G Ben Grubbs (Saints), OLB Jarret Johnson (Chargers), DE Cory Redding (Colts) and CB Domonique Foxworth

Grade after first wave of free agency: D. The Ravens lost three starters (Ben Grubbs, Jarret Johnson and Cory Redding) from last season's AFC North champion team and have yet to add anyone to replace them. It was a rough start to free agency for Baltimore, which didn't sign any of its first three visits (guard Evan Mathis, defensive end Mark Anderson and receiver-returner Ted Ginn Jr.). The toughest part of free agency was when the Ravens failed to sign Mathis, who re-signed with the Eagles, after Baltimore had just lost Grubbs.

Baltimore was able to keep two free-agent starters, Matt Birk and Jameel McClain, and boost a struggling special-teams group that allowed three touchdowns last season. The Ravens signed Cory Graham, a Pro Bowl special-teams player from the Bears; Brendon Ayanbadejo, a three-time Pro Bowl special-teams standout; and Sean Considine, who played special teams for three seasons under John Harbaugh in Philadelphia.

What’s next: The Ravens' biggest need is at left guard, but there might not be one that warrants being taken at No. 29. Wisconsin center-guard Peter Konz's stock has slipped recently even though he can play guard right away before switching to center in future seasons. It's hard to pin down a player for Baltimore, which can go in a lot of different directions in the first round.

The Ravens could take the best wide receiver available (especially if he's a returner) because they need a third target who can eventually take Anquan Boldin's starting spot. They could take a safety because Ed Reed turns 34 at the start of the season and Bernard Pollard is a free agent next year. And they could take an offensive tackle because they don't have a reliable backup and Bryant McKinnie is a free agent in 2013.

Pittsburgh Steelers

Key additions: None

Key losses: CB William Gay (Cardinals), LB James Farrior, NT Chris Hoke, G Chris Kemoeatu, DE Aaron Smith, WR Hines Ward

Grade after first wave of free agency: D. It's been a quiet free-agency period so far for the Steelers. Then again, it's usually quiet for the Steelers at this point in the offseason. The only team that consistently does less than the Steelers in free agency is the Green Bay Packers.

The Steelers avoided a failing grade because they've lost only two starters from last season's playoff team. James Farrior was cut in the team's salary-cap purge, and William Gay left as an unrestricted free agent. What Pittsburgh really lost in trimming $25 million to get under the cap was veteran depth and leadership. Injuries would force young players to step up into starting roles.

What’s next: There are question marks at running back, guard, inside linebacker, nose tackle and cornerback. Despite all of those needs, the consensus has been Pittsburgh will draft Alabama inside linebacker Dont'a Hightower if he's available at No. 24. He has a great combination of size and speed and excelled in a 3-4 defense in college. It seems like Hightower would be the perfect fit for Pittsburgh.

There's no chance that Memphis' Dontari Poe falls to the Steelers, but there some quality nose tackles in the draft. Those who should be available after the first round are: BYU's Loni Fangupo (second round), Washington's Alameda Ta'amu (third round) and Alabama's Josh Chapman (fourth round). The Steelers likely will become active later in free agency, especially in retaining their own players. Wide receiver Jerricho Cotchery, running back Mewelde Moore and quarterbacks Byron Leftwich and Charlie Batch could potentially return to the team.
