NFL Nation reporters pick out the biggest strength and the biggest weakness for every team heading into the 2016 season.

AFC East | AFC North| AFC South | AFC West

NFC East | NFC North | NFC South | NFC West

AFC EAST

Biggest strength: Cornerbacks. The Bills have two of the NFL's best in Stephon Gilmore and Ronald Darby, giving coach Rex Ryan the lockdown confidence on the outside that he needs to run his blitz-heavy scheme effectively.

Biggest weakness: Pass rush. In past years, this might have been their offensive line or quarterback, but now the Bills must prove they can get after passers after posting a mere 21 sacks last season. Jerry Hughes can't do it all himself. -- Mike Rodak

Biggest strength: Defensive line. Ndamukong Suh, Mario Williams and Cameron Wake combine for 12 career Pro Bowl appearances and they should be a force together this season.

Biggest weakness: Cornerbacks. Veteran Byron Maxwell is the only proven commodity out of this group and he struggled last season in Philadelphia. -- James Walker

Biggest strength: Elite play at quarterback with Tom Brady and top-level coaching to go with it. When it comes to places to start when building a team, those are usually the first two on the list.

Biggest weakness: Running back, where outside of Dion Lewis -- who is coming off a torn ACL from Nov. 7 -- there are a lot of question marks. -- Mike Reiss

Biggest strength: The defensive line has three blue-chip talents -- Muhammad Wilkerson, Sheldon Richardson and Leonard Williams. Each of the 300-pounders has double-digit sack potential.

Biggest weakness: Lack of quick-strike ability on offense. The Jets have talent at the skill positions, but there's no true home run threat. Statistically, Ryan Fitzpatrick was one of the worst deep-ball passers in the league last season. -- Rich Cimini

AFC NORTH

Biggest strength: Special teams. The Ravens return a Pro Bowl punter in Sam Koch and the second-most accurate field goal kicker in NFL history in Justin Tucker. Baltimore also has the best punt return team over the past three seasons and blocked five kicks in 2015.

Biggest weakness: Cornerbacks. Shareece Wright, who was re-signed to be a starter, has struggled with his technique in the first two preseason games, and nickelback Jerraud Powers has been a step slow in covering crossing patterns. This is a concern for a pass defense that allowed a franchise-worst 30 touchdown passes a year ago. -- Jamison Hensley

Biggest strength: Defensive line. The Bengals' Pro Bowl lineup of Carlos Dunlap and Geno Atkins combined for 24.5 sacks last season. Those two next to Michael Johnson and Domata Peko provide a line that has been consistently good.

Biggest weakness: Pass-catchers. It's hard to say any team with A.J. Green could have a weakness from the passing attack, but the Bengals' top two tight ends are hurt, and they don't have many options at receiver behind Green, with Brandon LaFell also nursing an injury and rookie Tyler Boyd unproven at this point. -- Katherine Terrell

Biggest strength: Tight end. Coming off a career season and contract extension, Gary Barnidge is a pro's pro, a tremendous route runner and a guy with great hands. Barnidge gives the offense a big and dependable target, which conceivably should open the field for players such as Josh Gordon and Corey Coleman.

Biggest weakness: Defensive front seven. There are no elite pass-rushers or any impact players. Teams will run on the Browns until February. -- Pat McManamon

Biggest strength: Vertical passing game. Quarterback Ben Roethlisberger throws the deep ball with precision. Going for 300-plus yards in the air is now considered an average day because of Pittsburgh's insistence on testing corners and safeties deep.

Biggest weakness: Secondary. This unit faces the most questions, particularly the starting corner spot opposite William Gay. But the Steelers have invested in several draft picks to bolster this spot. -- Jeremy Fowler

AFC SOUTH

Biggest strength: Front seven. This group is led by three-time defensive player of the year J.J. Watt, nose tackle Vince Wilfork and inside linebacker Brian Cushing. The Texans ranked fifth in the NFL with 45 sacks last season, and with Jadeveon Clowney, who looks poised for a breakout year, that number could increase in 2016.

Biggest weakness: An unproven offense. Aside from receiver DeAndre Hopkins and running back Lamar Miller, no other skill position players have produced at a high level before in the NFL. The pressure will be on quarterback Brock Osweiler and rookie receivers Will Fuller and Braxton Miller to produce right away. -- Sarah Barshop

Biggest strength: Quarterback. The Colts have used Andrew Luck's overall talents to make the playoffs in three of the past four seasons. And they'll continue to ride Luck's talents this season.

Biggest weakness: Offensive line and defense. The Colts' have struggled in these areas for the past four years. Indianapolis' inability to block well caused it to use five different quarterbacks last season. The Colts have finished 20th or worse on defense in three of Chuck Pagano's four seasons as coach. -- Mike Wells

Biggest strength: Playmakers. The Jaguars have a good supply of playmakers in wide receivers Allen Robinson and Allen Hurns and tight end Julius Thomas, and they added running back Chris Ivory in free agency. If WR Marqise Lee continues to stay healthy and performs the way he did in the spring, the Jaguars' offense could be one of the most potent in the NFL.

Biggest weakness: Offensive line, especially on the left side. LT Luke Joeckel hasn't become the dominant player the Jags hoped for when they drafted him No. 2 overall in 2013, and he may end up at left guard. Kelvin Beachum is coming off a torn left ACL and his effectiveness is in question. QB Blake Bortles has been sacked 106 times in his first two seasons -- some of which were his own fault -- and the O-line has to do a better job of protecting him. -- Mike DiRocco

Biggest strength: Running game. This should be an area of strength considering the Titans invested in two top backs -- DeMarco Murray and Derrick Henry -- as well as a new center in Ben Jones and a new right tackle in Jack Conklin.

Biggest weakness: Secondary. The defensive backs need to show they can be far better than last season's group and make some plays on the ball. They can start by not playing so far off receivers, which coaches don't want so often. -- Paul Kuharsky

AFC WEST

Biggest strength: The Broncos have speed across the depth chart and it shows, particularly in their depth at edge rusher and cornerback. Defensive coordinator Wade Phillips has the flexibility to rotate players and vary his looks so that the end result is Denver can consistently affect opposing quarterbacks in a wide variety of down and distance situations.

Biggest weakness: The Broncos don't know if it's actually a weakness yet, so it might simply be the biggest question right now: There is a scenario in which Denver has two quarterbacks -- Trevor Siemian and Paxton Lynch -- who have never started a regular-season game. Siemian has played just one regular-season snap overall (a kneel-down last December). There are decisions still to be made, but the Broncos have already shown they are not deterred by the prospect of youth at quarterback. -- Jeff Legwold

Biggest strength: Depth at running back. When Jamaal Charles is healthy, the Chiefs can go three deep like few teams in the NFL with Spencer Ware and Charcandrick West completing the trio. Ware and West combined to rush for more than 1,000 yards and score 11 touchdowns in Charles' absence last season.

Biggest weakness: Pass rush. The Chiefs went through training camp without either of their two top rushers, Justin Houston and Tamba Hali. With no indication that Houston will return any time soon, this could be a season-long problem. -- Adam Teicher

Biggest strength: Oakland's relative youth. Derek Carr, Amari Cooper and Khalil Mack have yet to turn 26 but they also have yet to experience a winning NFL season, which is something the Raiders have not done since 2002.

Biggest weakness: Well, more youth. Indeed, the biggest strength for this purportedly up-and-coming team is also its greatest weakness. In Oakland this season, it's youthful exuberance versus lack of grizzled experience, especially with the retirements of Charles Woodson and Justin Tuck. So who steps up? Carr and Mack believe it is up to them. -- Paul Gutierrez

Biggest strength: Philip Rivers. The Chargers QB hasn't missed a start in a decade and needs a little over 1,500 passing yards to eclipse Dan Fouts as the franchise's all-time passing leader.

Biggest weakness: Run defense. The 288 rushing yards San Diego gave up to the Titans was the most allowed by any team in Week 1 of preseason play. However, with the starters playing most of the first half, San Diego's defense allowed just 63 rushing yards in the Week 2 preseason game against the Arizona Cardinals. -- Eric D. Williams

NFC EAST

Biggest strength: Offensive line. The Cowboys have built their team through the offensive line with Tyron Smith, Travis Frederick, Zack Martin, La'el Collins and Doug Free. They signed Frederick to a six-year extension through 2023. They have Smith signed through 2023. They hope to sign Martin to a long-term deal next summer. There isn't a team in the NFL that doesn't envy the Cowboys' line.

Biggest weakness: Pass rush. Dallas hasn't been able to build through the draft on the defensive line as well as the O-line. DeMarcus Lawrence (second round, 2014) led the Cowboys in sacks last season with eight but will miss the first four games of 2016 because of a suspension. Randy Gregory (second round, 2015) is on the reserve/did not report list and is in a treatment facility. He is looking at a longer suspension than four games. Among the defensive linemen eligible to play Week 1, tackle Tyrone Crawford has the most sacks with eight. The Cowboys will have to make do with what they have up front this season. -- Todd Archer

Biggest strength: Passing offense. Eli Manning and Odell Beckham Jr., more specifically. The Giants are built around these two players, and without either, they are done. Manning's experience and pre-snap reads help them work around their offensive line deficiencies. Beckham draws the attention of multiple defenders. He's one of the most dangerous weapons in the league, as evidenced by his 25 touchdown receptions the past two years.

Biggest weakness: Right side of the offensive line. Right tackle Marshall Newhouse is a backup. Right guard John Jerry is an average starter. Their combined experience makes the right side of the Giants' line vulnerable. It's a good thing the Giants have Manning and Beckham to occasionally mask this weakness. -- Jordan Raanan

Biggest strength: Defensive line. Fletcher Cox and Vinny Curry lead a front that should do plenty of damage in Jim Schwartz's attack 4-3 scheme. With Connor Barwin, Brandon Graham and Bennie Logan also in the mix, this looks to be the most potent unit on the team.

Biggest weakness: Wide receiver. To this point, no player has grabbed a leading role alongside Jordan Matthews. While there is talent in the room, from Nelson Agholor to the newly acquired Dorial Green-Beckham, questions persist as to whether the Eagles have enough on the outside to give the offense the type of production it needs. -- Tim McManus

Biggest strength: The passing game. That starts with the receiving talent -- DeSean Jackson, Pierre Garcon, Jamison Crowder and tight end Jordan Reed. The Redskins are able to create matchup issues because of this talent. They have speed (Jackson), toughness (Garcon), quickness (Reed) and shiftiness (Crowder). And they're good enough that first-round pick Josh Doctson, still out with Achilles tendinitis, isn't even missed. But the team also features an offensive line that protects well and a quarterback in Kirk Cousins who understands where to go with the ball. The Redskins will be more aggressive on certain downs (first) with passing the ball this season. Their play-action game could be scary on this down, with the addition of tight end Vernon Davis.

Biggest weakness: The run defense. The Redskins have to prove they're better than last season when they ranked 31st in the NFL, allowing 4.80 yards per carry. Last season they struggled to get off blocks up front -- especially in nickel packages -- and therefore struggled to make plays. Washington's secondary should be improved, but the front must do its part on early downs. There are questions about the pass rush, but the team can be put in better situations with stronger run defense, leading to more third-and-long situations. -- John Keim

NFC NORTH

Biggest strength: Defensive coordinator Vic Fangio and his staff. Chicago did plenty of work to upgrade the defense in the offseason, but Fangio's coaching style is what ties it all together. The Bears are fortunate to have such an experienced and respected coordinator to oversee the rebuild on defense.

Biggest weakness: Lack of overall roster depth. The Bears are a couple more key injuries (offensive line, cornerback, tight end, wide receiver) away from being in serious trouble in the NFC North. -- Jeff Dickerson

Biggest strength: Defensive front. Having a defensive front that can rotate and initiate attack has been a priority for new defensive coordinator Teryl Austin because it helps out the rest of the scheme. This year's line has a star in pass rushing end Ezekiel Ansah, a former All-Pro in Haloti Ngata and a couple of emerging players in end Devin Taylor and tackle Tyrunn Walker. This might be Detroit's deepest defensive line in years and an obvious strength.

Biggest weakness: Offensive line. While Riley Reiff (RT) and Larry Warford (RG) have looked good, the Lions have questions at center with Travis Swanson, and at left guard with Laken Tomlinson. And the left tackle, Taylor Decker, is a rookie who will have some issues as he learns. This is a weakness for the Lions and could cause some major problems if they can't protect Matthew Stafford long enough to make correct reads or open up holes for Ameer Abdullah. -- Michael Rothstein

Biggest strength: The Packers' biggest strength is their winning experience, culture and internal expectations. They're one of only two teams (the Patriots are the other) to make the playoffs each of the past seven years, and young players quickly learn from the veterans what is expected around Green Bay.

Biggest weakness: If there's a weakness, it's on the defensive line, where inexperience dominates. Going into Week 1, the only defensive linemen available who have played in an NFL regular-season game are Mike Daniels and Letroy Guion. -- Rob Demovsky

Biggest strength: The Vikings' defense has become the identity of the team, and it's also their biggest strength heading into 2016. Coach Mike Zimmer's double-A gap blitz package has helped turn the Vikings into one of the league's best pass rushing defenses, and the group should disrupt quarterbacks again this season.

Biggest weakness: The Vikings' biggest weakness also involves a pass rush -- namely, their inability to stop one from affecting Teddy Bridgewater. No quarterback in the league was pressured more often last season, and the Vikings spent considerable resources trying to fix their offensive line before 2016. -- Ben Goessling

(Editor's note: The information above was published prior to Bridgewater's injury on Tuesday at practice).

NFC SOUTH

Biggest strength: Julio Jones. Arguably the league's most dominant receiver coming off a season in which he fell just 129 yards shy of an NFL-record 2,000 receiving yards. And Jones is always striving to be better.

Biggest weakness: The pass rush. The Falcons had a league-low 19 sacks last season, but they hope the addition of veteran Dwight Freeney will improve that number dramatically. Plus, much is expected from former eighth overall pick Vic Beasley Jr. in Year 2. -- Vaughn McClure

Biggest strength: Quarterback Cam Newton. The threat the NFL MVP creates in the run and pass game keeps defensive coordinators up at night. Add No. 1 receiver Kelvin Benjamin back into the mix with the rest of the starters returning, and Newton will be even more dangerous.

Biggest weakness: Secondary. I easily could have said the defense was the strength since it has ranked in the top 10 each of the past four seasons. But since the weakness is a secondary that likely will include two rookie starters, it seemed like a conflict. But from what I've seen of the corners thus far the weakness doesn't appear terribly weak. -- David Newton

Biggest strength: Passing attack. For the 11th straight year, the Saints' biggest strength is their passing attack. QB Drew Brees has led the NFL in passing yards for four of the past five seasons -- and the Saints might be even more dynamic after adding rookie WR Michael Thomas and veteran TE Coby Fleener to complement rising star receiver Brandin Cooks.

Biggest weakness: Defense. The defense is coming off a historically bad season in which it shattered the NFL record for TD passes allowed (45). The D can't help but be better -- and it has been very good for most of the preseason. But the pass rush remains a huge question mark, especially after injuries to young linemen Hau'oli Kikaha and Sheldon Rankins. -- Mike Triplett

Biggest strength: Running game. The Bucs will continue to be a run-first offense. Doug Martin is a tough inside and outside runner, while Charles Sims gives them great flexibility as a runner in the short passing game and downfield. An honorable mention on the strength meter is the Bucs have a lot more depth along the defensive line this season.

Biggest weakness: Kicking game. Roberto Aguayo has missed three kicks in two preseason games and is now struggling in practice. In the third preseason game against the Browns, Aguayo made three field goals, including a 48-yarder, and he made all three extra points. Does that mean the kicking woes are officially behind him? We'll find out soon enough. -- Jenna Laine

NFC WEST

Arizona Cardinals

Biggest strength: Offensive continuity. The Cardinals return every playmaker from a year ago, meaning everyone who caught a pass from Carson Palmer and everyone who scored an offensive touchdown in 2015 are back.

Biggest weakness: Uncertainty at starting right cornerback. It would have been Justin Bethel's job had he not fractured his foot and required offseason surgery. While he was on the mend, rookie cornerback Brandon Williams won the starting job for now with an impressive OTAs, minicamp and start to training camp. Bethel, who just recently returned to practice, further hurt his case by missing the first three weeks of training camp after suffering a setback a few weeks before camp began. -- Josh Weinfuss

Biggest strength: Running game. The Rams' ground attack is anchored by the boundless ability of star tailback Todd Gurley, who finished third in rushing yards as a rookie despite having to wait until Week 4 to receive a sizable workload. Benny Cunningham, Malcolm Brown and Aaron Green have also impressed throughout training camp, giving the Rams plenty of depth in the backfield despite the bizarre absence of Tre Mason.

Biggest weakness: The passing game. The Rams finished last in passing yards, passing touchdowns and QBR last season, and their hopes for a turnaround in that department will fall largely on four rookies -- quarterback Jared Goff, receiver Pharoh Cooper, and tight ends Tyler Higbee and Temarrick Hemingway. -- Alden Gonzalez

Biggest strength: Secondary. There might not be a true superstar in the bunch, but there's no shortage of capable players back there. Antoine Bethea provides the steady veteran presence at safety with Eric Reid and Jaquiski Tartt offering a lot of upside. And at cornerback, Tramaine Brock remains underrated and surrounded by an eclectic mix of skills in Jimmie Ward, Rashard Robinson, Will Redmond, Chris Davis, Keith Reaser and others. The 49ers figure to have some tough decisions to make here when setting the 53-man roster, which is a good thing.

Biggest weakness: Quarterback. Until the Niners find a good resolution, it's hard to pinpoint anything other than QB. Yes, the receiver corps could use some help, but the choice between Blaine Gabbert and Colin Kaepernick as the starting quarterback still doesn't inspire much confidence. Coach Chip Kelly's offense has made stars of lesser quarterbacks in the past so there is hope, but it's clear an upgrade would provide the offense a much higher ceiling. -- Nick Wagoner

Biggest strength: The secondary. The Seahawks return cornerback Richard Sherman, along with safeties Earl Thomas and Kam Chancellor. Jeremy Lane and DeShawn Shead are versatile players capable of playing either right cornerback or nickel. This is a deep and talented group that will once again make life difficult for opposing quarterbacks.

Biggest weakness: The offensive line. No surprise here. The Seahawks are spending less money on their offensive line than any other team in the NFL. They will have at least three new starters, and Justin Britt, who played left guard last season, is making the switch to center. The interior of the line -- with Mark Glowinski, Britt and Germain Ifedi -- has looked good throughout camp. But the tackle spots, where Bradley Sowell, Garry Gilliam and J'Marcus Webb are competing for playing time, remains a serious question mark. -- Sheil Kapadia
