Linebacker:

1. Zach Brown
2. Kevin Minter
3. Perry Riley
4. Gerald Hodges
5. DeAndre Levy
6. Daryl Smith
7. Sio Moore
8. Sean Spence
9. Manti Te’o
10. Mike Morgan
11. Keenan Robinson
12. Nick Bellore
13. D’Qwell Jackson
14. Erin Henderson
15. Josh Bynes

While players at other defensive positions have flown off the board, there’s been almost no movement among off-ball linebackers. Only five of PFR’s original top-15 free agent linebackers have signed new contracts, a group that includes Dont’a Hightower, our previous No. 1 ‘backer who re-signed with the Patriots today. Zach Brown, who now holds that honor, broke out in his fifth NFL campaign and played especially well in coverage, a skill that should lead to a handsome reward. Brown, 27, met with the Raiders today, while the Dolphins also hope to schedule a visit.

The Bengals, specifically, are in the linebacker market, as they’ve met with both Kevin Minter and Keenan Robinson in recent days. But the rest of the players on this list aren’t drawing much interest as of yet, a fact that speaks to the devaluation of the linebacker position. Teams will pay up for a three-down linebacker like Hightower, but if a player can be formation-ed off the field, he’s not going to land a hefty deal.

One linebacker who did prove he could stay on the field on third down was Perry Riley, who played 370 coverage snaps for the Raiders last season. Riley is still only 28 years old, but posted awful marks from Pro Football Focus during his previous campaigns with Washington. Whether it was Oakland’s scheme (including its talented pass rushers) that allowed Riley to flourish, or a true breakout coming in the middle of a career, Riley could help a number of clubs. The Raiders are reportedly working to bring him back.

Cornerback:

1. Morris Claiborne
2. Brandon Carr
3. Nickell Robey-Coleman
4. Darrelle Revis
5. Brandon Flowers
6. Patrick Robinson
7. Sterling Moore
8. Alterraun Verner
9. Sam Shields
10. Tramon Williams
11. Jerraud Powers
12. B.W. Webb
13. Valentino Blake
14. Leon Hall
15. Leodis McKelvin

The top two corners still on the open market are both former Cowboys, and Brandon Carr looks like the surer bet to return to Dallas at this point. Morris Claiborne, meanwhile, has drawn interest from the Ravens, and most opposing clubs believe he’ll end up signing with Baltimore. Clairborne, 27, appeared to be a prime overpay candidate heading into the offseason, but if the Ravens can land him on a short-term deal, they’d be making a wise investment.

Nickell Robey-Coleman was surprisingly cut loose by the Bills earlier this offseason, and the 25-year-old has already drawn interest from numerous teams, with the Vikings, Chargers, Dolphins, Steelers, and Titans all considering a run at the slot man. Like Robey-Coleman, Alterraun Verner, Valentino Blake, and Leon Hall are all probably best sticking to slot duty, while Hall can even offer safety versatility.

Now that all charges have been dropped against Darrelle Revis, he’ll make for an interesting test case in free agency. Clearly, Revis is not the shutdown corner he once was, and may even be mulling a move to safety as he closes his career. But clubs in the market for secondary help could do worse than Revis, and he should be on a roster when the regular season rolls around.

Safety:

1. Darius Butler
2. T.J. McDonald
3. Bradley McDougald
4. Corey Graham
5. Jairus Byrd
6. Lardarius Webb
7. Rashad Johnson
8. Rafael Bush
9. Daimion Stafford
10. Steven Terrell
11. Kendrick Lewis
12. Duke Ihenacho
13. Chris Prosinski
14. Donte Whitner
15. Aaron Williams

Tony Jefferson, Duron Harmon, and Barry Church all came off the board quickly, leaving Darius Butler as the top safety who is still unsigned. Butler is 30 years old, but as a former cornerback, offers the type of coverage skills that NFL teams are looking for in today’s passing league. He’s taken a visit with the Bears (who have already added Quintin Demps), while a return to Indianapolis is still possible.

Most of the safeties on this list are in-the-box types — that’s thanks to the fact that center field-esque safeties are more rare and thus more expensive. Recently-released veterans such as Jairus Byrd, Lardarius Webb, and Corey Graham, however, offer coverage ability and would make for decent signings on short pacts. T.J. McDonald and Bradley McDougald, on other hand, are big hitters that will patrol near the line of scrimmage. McDougald, specifically, will take a visit with the Seahawks this week.

Chris Prosinski is just a special teamer, but he’s a great special teamer. While he only played 173 defensive snaps in 2016, he saw time on more than 80% of the Bears’ special teams plays, and was listed as one of the season’s best special teams players by Gordon McGuinness of Pro Football Focus. Football Outsiders ranked the Cardinals, Jets, and Texans as the bottom-three teams in special teams DVOA, and any of those clubs would benefit from adding Prosinski.

Kicker:

1. Nick Folk
2. Dan Carpenter
3. Mike Nugent

Demand is not high for placekickers at the moment, as only the Giants and Bengals stand out as clubs that immediately need a kicker. Injuries and ineffectiveness are sure to strike the position, however, at which point the specialists on this list will surely receive calls. Dan Carpenter and Mike Nugent missed a combined 11 extra points in 2016, and given that he topped both Carpenter and Nugent in field goal percentage, Nick Folk should be the first kicker on clubs’ emergency list.
