theScore goes division by division to identify the biggest need for all 32 NFL teams entering free agency, which opens March 13 at 4 p.m. ET

AFC West

Denver Broncos

Biggest need: Defensive line

Von Miller is a one-man wrecking crew, but he shouldn't always be required to be, especially as he approaches his 30th birthday. With Denver still potentially set to use its first-round pick on a quarterback after acquiring Joe Flacco, John Elway should spend big to fix the interior of the defensive line to free up Miller and running mate Bradley Chubb.

Top potential FA targets: Ndamukong Suh, Sheldon Richardson

Kansas City Chiefs

Biggest need: Secondary

Kansas City can go touchdown-for-touchdown with any offense in the league, but even Patrick Mahomes can't continue to overcome his team's woeful defensive backfield, which allowed the second-most yards through the air in 2018. Adding a playmaking cornerback or safety in free agency would give the Chiefs the counter-punch they need to complement their explosive offense.

Top potential FA targets: Earl Thomas, Ronald Darby

Los Angeles Chargers

Biggest need: Defensive tackle

The Chargers' roster is one of the most well-rounded in the NFL, but there's a glaring hole right in the center of the defense. Corey Liuget's option was declined, meaning he will test the open market along with three other defensive tackles from 2018. Los Angeles has to add multiple bodies up front, and while the draft is deep at the position, experienced veterans are needed to help end Philip Rivers' long wait for a ring.

Top potential FA targets: Ndamukong Suh, Sheldon Richardson

Oakland Raiders

Biggest need: Front seven

The Raiders could overhaul nearly every position on their roster (which is what Jon Gruden appears to be doing) and few would argue against it. But the talent on defense is particularly bad. The secondary has several exciting pieces, such as Gareon Conley and Karl Joseph, but the defensive line and linebacking corps both need a serious infusion of playmakers if Gruden is to return to winning ways in 2019.

Top potential FA targets: C.J. Mosley, Trey Flowers, Muhammad Wilkerson

NFC West

Arizona Cardinals

Biggest need: Offensive line

Whether it's Josh Rosen or Kyler Murray under center for the Cardinals, priority No. 1 must be improving the offensive line after Arizona trotted out 11 different linemen in 2018. Even middling offensive linemen command significant deals in free agency due to a lack of options (see Nate Solder), but Arizona can't get cheap when it comes to protecting its franchise player and should target free agency's top pass-protectors.

Top potential FA targets: Trent Brown, Matt Paradis

Los Angeles Rams

Biggest need: Pass-rusher

The Rams tried to fix their lack of pass rush by acquiring Dante Fowler Jr. at last season's trade deadline, but their inability to get edge pressure was still evident in the postseason. While paying a big name is out of the question after Aaron Donald's monster deal, veterans could be convinced to sign an affordable short-term deal to play on a Super Bowl contender.

Top potential FA targets: Cameron Wake, Ezekiel Ansah

San Francisco 49ers

Biggest need: Free safety

The 49ers desperately need to boost their pass rush after tying for 22nd in sacks last season, but adding edge rushers isn't the only way to fix the issue. Coordinator Robert Saleh's single-high Cover 3 defense requires a rangy free safety to patrol the deep middle of the field to make it effective, which is why reuniting Earl Thomas with fellow former Legion of Boom member Richard Sherman makes so much sense. He won't come cheap, however, so San Francisco would be smart to identify a Plan B.

Top potential FA targets: Earl Thomas, Lamarcus Joyner, George Iloka

Seattle Seahawks

Biggest need: Pass-rusher

The Seahawks used the franchise tag on Frank Clark after he emerged as the team's best sack artist in 2018 with 13 QB takedowns. But Clark needs backup. While defensive tackle Jarran Reed made a big leap as a pass-rusher, racking up 10.5 sacks, Seattle needs more edge talent if it's to terrorize opposing passers as it did in the days of Michael Bennett, Cliff Avril, and Co. The leading pass-rushers will command huge contracts, so Seattle should target the second tier of available defensive ends.

Top potential FA targets: Ezekiel Ansah, Dante Fowler Jr., Cameron Wake

AFC East

Buffalo Bills

Biggest need: Wide receiver

Josh Allen was one of the league's worst passers during his first season in the NFL; only fellow rookie Josh Rosen had a lower QB rating. But Allen's struggles are understandable given his supporting cast of offensive linemen and receivers. Allen's athleticism mitigates his line's issues to an extent, so Buffalo should focus on finding its young pivot pass-catchers who can either stretch the field or excel after the catch to play alongside promising second-year wideout Robert Foster.

Top potential FA targets: Golden Tate, John Brown, Adam Humphries, Mike Wallace

Miami Dolphins

Biggest need: Quarterback

Ryan Tannehill is reportedly done in Miami after seven years. The Dolphins now need to find their latest "next Dan Marino," but as they sit at No. 13 overall in the draft, it'll be hard to land Dwayne Haskins or Kyler Murray without moving up. A stop-gap option is therefore needed, and outside of making a shock trade for a quarterback like Jacoby Brissett, Miami will need to land one of the two potential starters on the free-agent market.

Top potential FA targets: Nick Foles, Teddy Bridgewater

New England Patriots

Biggest need: Pass-catchers

Josh Gordon might be done with football (again), Rob Gronkowski is widely expected to retire, and Julian Edelman turns 33 in May. Tom Brady desperately needs some new weapons. The Patriots rarely shell out big bucks in free agency, so the likes of Golden Tate and Tyrell Williams aren't realistic. Expect New England to target reclamation projects that it can squeeze every ounce of production from.

Top potential FA targets: Demaryius Thomas, Cole Beasley, Devin Funchess, Tyler Eifert

New York Jets

Biggest need: Running back

Sam Darnold looked every bit a franchise passer down the stretch last season. However, handing him the keys to the offense risks putting too much on his shoulders too soon. A dynamic ground game is always a young passer's best friend. With Isaiah Crowell likely to be shown the door, there's no doubt the Jets must find a new starter. The only question is: how much are they willing to spend?

Top potential FA targets: Le'Veon Bell, Tevin Coleman, Mark Ingram

NFC East

Dallas Cowboys

Biggest need: Defensive line

The Cowboys had little choice but to franchise-tag star pass-rusher DeMarcus Lawrence for a second consecutive season. Just days prior, they lost both Randy Gregory and David Irving to indefinite suspensions. The pair combined for seven sacks in 2018, and though they accounted for just one start between them, their absences for 2019 will affect the depth on the defensive line.

Top potential FA targets: Ndamukong Suh, Domata Peko, Shane Ray

New York Giants

Biggest need: Secondary

If the Giants bring in a quarterback to challenge - or perhaps replace - Eli Manning, it'll be through the draft. Free agency should be all about defense for New York. With Landon Collins avoiding the franchise tag and cornerback Janoris Jenkins potentially being a cap casualty, a revamp of the entire secondary could be in the cards.

Top potential FA targets: Ronald Darby, Tre Boston, Bradley Roby

Philadelphia Eagles

Biggest need: Running back

The Eagles' current group of running backs - Wendell Smallwood, Corey Clement, Josh Adams, and Boston Scott - is full of useful role players but lacks a standout option to rely on with Jay Ajayi hitting free agency. Re-signing the oft-injured veteran to a prove-it deal is an option, but the Eagles likely won't want injuries to severely hamper their run game again. A home-run threat like Tevin Coleman could help Philly's offense return to the level of its 2017 Super Bowl run.

Top potential FA targets: Le'Veon Bell, Tevin Coleman, Jay Ajayi

Washington Redskins

Biggest need: Quarterback

Alex Smith reportedly won't play in 2019 after a devastating leg injury, but his $20.4-million cap hit isn't going anywhere. Josh Johnson and Colt McCoy are, at best, mediocre backups, and the former is a free agent. While the Redskins are likely to draft a first-round quarterback, they did also show interest in trading for Joe Flacco. There are several big names on the market, but Washington doesn't have a ton of cap space; a free-agent bidding war could end its chances of landing a veteran pivot.

Top potential FA targets: Teddy Bridgewater, Nick Foles, Tyrod Taylor

AFC North

Baltimore Ravens

Biggest need: Wide receiver

Lamar Jackson's passing remains a work in progress. If he's to make improvements in that part of his game, the Ravens will have to supply him with a replenished stable of receivers. With John Brown set to hit free agency, Jackson's top targets are Willie Snead and two tight ends from the 2018 draft.

Top potential FA targets: Tyrell Williams, Golden Tate, Devin Funchess

Cleveland Browns

Biggest need: Defensive tackle

Now that Greg Robinson has been retained, the Browns should turn their attention to the interior of the defensive line. The position is barren behind former third-round pick Larry Ogunjobi, who impressed with 5.5 sacks in 2018. Cleveland has the cap space to target the best defensive tackles available.

Top potential FA targets: Timmy Jernigan, Ndamukong Suh, Sheldon Richardson

Cincinnati Bengals

Biggest need: Linebacker

New defensive coordinator Lou Anarumo's first inclination would likely have been to address the Bengals' secondary, considering his background as a DBs coach. However, the more pressing need is to restock the linebacker corps, one that sees Preston Brown and Vincent Rey headed to free agency and veteran Vontaze Burfict a candidate to be cut.

Top potential FA targets: KJ Wright, Kwon Alexander, Anthony Barr

Pittsburgh Steelers

Biggest need: Cornerback

Le'Veon Bell is gone and Antonio Brown is headed out the door behind him. The natural reflex is to find replacements for those marquee talents. The sensible move would be to find a No. 2 corner to play opposite Joe Haden.

Top potential FA targets: Morris Claiborne, Ronald Darby, Bryce Callahan

NFC North

Chicago Bears

Biggest need: Kicker

The Bears are in an enviable position. They own a roster so stocked with talent that their biggest need is one that doesn't have to be addressed through the draft. Chicago is set to cut ties with Cody Parkey. Luckily, a couple of veteran replacements are available on the free-agent market.

Top potential FA targets: Stephen Gostkowski, Jason Myers

Detroit Lions

Biggest need: Pass-catchers

Not long ago, Detroit was thought to have one of the stronger receiving corps in the league. Golden Tate has since been traded and TJ Jones joins tight ends Luke Willson and Levine Toilolo in free agency. And it must have hurt to see Eric Ebron flourish in Indianapolis. If Matthew Stafford and the Lions are to turn things around, they'll need more offensive weapons.

Top potential FA targets: Jamison Crowder, Jared Cook, Devin Funchess

Green Bay Packers

Biggest need: Edge rusher

Clay Matthews, Jake Ryan, and Muhammad Wilkerson are all set to become free agents. With or without that triumvirate, the Packers need a pass rush that will help take pressure off of their young, developing corners. Luckily for Green Bay, the draft is ripe with future star defensive linemen. Unfortunately for the Pack, they own the No. 12 pick and could miss out. At least there's free agency.

Top potential FA targets: Trey Flowers, Dante Fowler Jr., Ezekiel Ansah

Minnesota Vikings

Biggest need: Offensive line

The Vikings' biggest area of need isn't up for debate. From tackle to guard, Minnesota needs better play along the entire offensive line. If they're to make the most out of their $84-million investment in Kirk Cousins, the Vikings must protect him and allow him more time to throw. They have little cap space to play with and therefore will have to get creative to find the necessary funds to plug the holes on their O-line.

Top potential FA targets: Ramon Foster, Rodger Saffold, Ja'Wuan James

AFC South

Houston Texans

Biggest need: Offensive line

Deshaun Watson was sacked a league-high 62 times in 2018, and those struggles to protect the franchise quarterback cost the Texans in the wild-card game. As the home team and division champion, Houston was upset by rival Indianapolis after scoring just seven points and allowing three sacks and eight QB hits on Watson. Pass protection is the Texans' Achilles heel.

Top potential FA targets: Trent Brown, Ja'Wuan James, Mitch Morse

Indianapolis Colts

Biggest need: Cornerback

Pierre Desir impressed in his second season in Indianapolis, so the Colts should make it a priority to bring the 28-year-old back. Armed with the most cap space of any team, Indy has the capacity to re-sign Desir and target the top free agents at the position to play alongside him.

Top potential FA targets: Ronald Darby, Pierre Desir, Bryce Callahan

Jacksonville Jaguars

Biggest need: Quarterback

The belief in Jacksonville is that the Jaguars were one competent quarterback away from reaching the Super Bowl in 2017. While they can't go back in time to rectify that situation, management is finally intent on making a change under center. Blake Bortles' time has run out as the Jaguars are reportedly the only bidder for Super Bowl LII MVP Nick Foles.

Top potential FA targets: Nick Foles, Teddy Bridgewater

Tennessee Titans

Biggest need: Outside linebacker

Brian Orakpo's retirement and Derrick Morgan's expiring contract leave the Titans with an obvious need at outside linebacker. While the pair's production dropped off substantially in 2018, the veterans still leave glaring holes. A likely target is Za'Darius Smith, whom defensive coordinator Dean Pees knows well from his time in Baltimore.

Top potential FA targets: Za'Darius Smith, Preston Smith, Aaron Lynch

NFC South

Atlanta Falcons

Biggest need: Offensive line

Both starting left guard Andy Levitre and backup right guard Ben Garland aren't expected to return in 2019 and general manager Thomas Dimitroff has openly considered taking a guard with Atlanta's first pick in April's draft. With little cap room to play with, it's a likely scenario. The Falcons were sixth in quarterback hits allowed in 2018 and are therefore open to making improvements across the offensive line.

Top potential FA targets: Mike Iupati, James Carpenter, LaAdrian Waddle

Carolina Panthers

Biggest need: Center

The Panthers need help along the offensive line, but there's no bigger hole than at center after the retirement of 12-year pro Ryan Kalil. If Carolina opts to find a veteran replacement rather than start fresh through the draft, it'll likely have to pay up for the top players available at the position.

Top potential FA targets: Mitch Morse, Matt Paradis, John Sullivan

New Orleans Saints

Biggest need: Tight end

Following Benjamin Watson's retirement, the Saints are thin at the tight end position with sparingly used options Josh Hill and Garrett Griffin. There was a belief that New Orleans would seek a reunion with Jimmy Graham, but the Packers expect him back in 2019. Still, there are reliable hands available on the open market that could make the third highest-scoring offense even more dangerous.

Top potential FA targets: Jared Cook, Jesse James

Tampa Bay Buccaneers

Biggest need: Secondary

The Buccaneers have ranked in the bottom third in pass defense in each of the past three seasons. Though the offense has finished in the top 10 in points scored over the past two seasons, the Bucs can't seem to allow fewer points than they score. They're currently set to enter 2019 with one of the youngest secondaries in football, headlined by Vernon Hargreaves, Carlton Davis, and Justin Evans. Tampa needs back-end help in the worst way.

Top potential FA targets: Tyrann Mathieu, Glover Quin, Bradley Roby
