Biggest storyline for each team as NFL training camp approaches

Arizona scored a league-low 225 points last season, so it wasn't a surprise when they hired an offensive-minded head coach in the offseason. The surprise was that it was Kingsbury, who was fired by Texas Tech last year due to his limited overall team success. Kingsbury has been at the helm of some spectacular offenses, however, and he has rookie Kyler Murray under center. The Cardinals might not be ready to win many games in 2019, but they should be entertaining.

After a disappointing 7-9 season, the Falcons cleaned house by firing coordinators Steve Sarkisian, Marquand Manuel and Keith Armstrong. Dan Quinn led the Falcons to the Super Bowl just three years ago, but 2019 could be a make-or-break year for him after the team has regressed since then. The return of offensive coordinator Dirk Koetter at least puts the offense in a good place, considering his past success working with Matt Ryan from 2012-14. Former Chiefs defensive coordinator Bob Sutton has effectively become the defensive head.

The Ravens transitioned to becoming the most run-heavy offense in football when Lamar Jackson replaced Joe Flacco last season, and the team is going all in on that trend after promoting Greg Roman to offensive coordinator and signing veteran running back Mark Ingram. It remains to be seen if the style of offense can succeed over a full season. While Jackson has been working on his throwing accuracy, that's still very much a work in progress.

After making the playoffs in Sean McDermott's first season as head coach, the Bills predictably regressed last season. They've taken significant steps to surround second-year quarterback Josh Allen with more talent, including the additions of center Mitch Morse, wideouts John Brown and Cole Beasley and running back Frank Gore. It still remains to be seen if those additions will be enough for the Bills to return to playoff football.

The Panthers disappointed last season, but much of that decline was due to Cam Newton trying to play through a shoulder injury and eventually getting shut down late in the year. He's healthy for training camp following shoulder surgery, but the team addressed quarterback depth in drafting Will Grier. Newton is entering his age 30 season and has taken on as much contact as any quarterback in recent memory. The Panthers can get back to the playoffs if Newton can stay healthy, but that could become more difficult as he ages.

Chicago's surprising 201- season ended in disappointing fashion when Cody Parkey missed a game-winning, 43-yard field goal attempt in the wild-card round. The Bears failed to address the spot with a proven kicker this offseason after releasing Parkey, and it still remains to be seen how the spot will be filled.

The Bengals finished 6-10 last season, and much of their struggles were due to the defense. They allowed 455 points and a league-worst 6,618 yards. While the team has seen some changes in personnel during the offseason, they weren't quite as drastic as expected. New defensive coordinator Lou Anarumo has a tough job ahead.

The Browns won the offseason, with huge additions led by Odell Beckham Jr. It's clear general manager John Dorsey wants to win this year, following a season where the team won five of its last seven games last season. Cleveland is the early favorite to win the AFC North, which is a drastic change given the recent dominance of the Steelers and Ravens. The team expects second-year quarterback Baker Mayfield to make a giant leap this season, but it remains to be seen if Cleveland is truly ready to compete as one of the top dogs in the AFC.

It seems like a foregone conclusion that the Cowboys will pay Dak Prescott, but it still hasn't happened as he enters the final season of his rookie deal. Prescott was a godsend as a fourth-round pick who was on standby when Tony Romo got injured in 2016. He successfully rebounded last year after a subpar sophomore season. However, until an extension is announced, Prescott's status could be a team distraction, something the Cowboys can ill-afford as they try to make another playoff run.

Quarterback has been a problem for the Broncos since Peyton Manning's retirement. Case Keenum clearly wasn't the answer last season, but the team doubled up at the position this year by trading for Joe Flacco and drafting Drew Lock in the second round. Flacco has struggled with the Ravens recently and is now in a similar situation to last year, effectively being used as a placeholder for a rookie. It's unclear exactly how the situation will unfold, but Lock's eventual ascent to the starting role seems inevitable.

Year 1 of the Matt Patricia experience in Detroit didn't go well, as the former Patriots defensive coordinator went 6-10, finishing last in the NFC North. The Lions hired Patricia because they wanted to take the team to the next level, but they took a significant step back last season. The Lions continue to transition their defensive personnel to Patricia's system, most notably signing Trey Flowers this offseason. They likely need to show significant improvement this year, or Patricia could be fired.

The Packers offense started to become stale last season before firing head coach Mike McCarthy. There was also a clear disconnect between McCarthy and Aaron Rodgers, but the Packers hope they've made Rodgers happier by hiring Matt LaFleur. A disciple of Sean McVay, LaFleur will certainly be more creative, but it remains to be seen if it will lead to more success on the field.

Deshaun Watson was sacked more than any quarterback in football last season, as the Texans offensive line continued to disappoint after major offseason moves. The Texans tried again this offseason, drafting offensive linemen Tytus Howard and Max Scharping with two of their first three picks. Houston hopes the offensive line is finally solved.

Even after a highly productive return from Andrew Luck, Indy was lacking many receiving weapons on offense. The Colts made a splash by signing Devin Funchess and drafting speedy Parris Campbell in the second round, and the team is also set to get tight end Jack Doyle back from injury. With that group, in addition to T.Y. Hilton and Eric Ebron, Luck now has more than enough talent around him.

Jaguars fans have weathered terrible quarterback play for the last decade, but they're hoping former Super Bowl MVP Nick Foles can be their savior. He revitalized his career in Philadelphia, but the Eagles also had a significantly better supporting cast than Jacksonville. Foles is familiar with new coordinator John DeFilippo's offense, which should help the transition.

The Chiefs fell just short of making the Super Bowl last year due to their defense, as New England marched down the field during overtime of the AFC championship game. The team fired defensive coordinator Bob Sutton and installed Steve Spagnuolo's 4-3 defense. The Chiefs also made huge personnel changes, getting rid of Justin Houston, Dee Ford and Eric Berry in favor of Frank Clark and Tyrann Mathieu, among others. The team needs the defense to be only average, given how well the offense has played with Patrick Mahomes at quarterback.

The Chargers took a giant step forward last season, going 12-4 and making the playoffs for the first time since 2013. They still have a small window to bring a Super Bowl home with Philip Rivers still going strong, as well as a roster that's as complete and balanced as any in football. Anything short of advancing to the AFC championship this year would probably be a disappointment.

Todd Gurley sat late last season and was used in tandem with C.J. Anderson during the playoffs due to what we later found out were chronic knee issues. The Rams used a third-round pick on Memphis running back Darrell Henderson, showing even more concern regarding Gurley's health this year. The Rams offense hasn't been quite the same without Gurley on the field, and they probably need him to last all season to make it back to the Super Bowl.

Miami signed veteran Ryan Fitzpatrick before acquiring 2018 first-round pick Josh Rosen from Arizona this offseason. The pairing gives Miami a formidable competition going into training camp in what was figured to be a rebuilding year with a new coaching staff. The team is hoping one of those quarterbacks gives fans something to be excited about.

Minnesota fell short of the Super Bowl in 2017 and thought it was a top-end quarterback away from a Super Bowl berth. Thus, the Vikings signed Cousins to a mammoth contract last year, only to regress across the board, finishing 8-7-1 in 2018. Cousins showed flashes but floundered in critical moments. The move could be considered a massive disaster if the Vikings fail to get back to the playoffs this year.

The Patriots always seem to make things work as long as Tom Brady has been under center. However, they took some big losses this offseason after winning their sixth Super Bowl in the Brady era, particularly the retirement of tight end Rob Gronkowski. The team still has Julian Edelman but otherwise has a bunch of question marks at wide receiver and tight end as Brady enters his age 42 season.

Saints fans are still bitter at the pass interference no-call in the NFC championship that prevented the team from advancing to the Super Bowl. Fortunately, New Orleans looks equipped for one more run with Drew Brees under center, bringing back nearly all of its key pieces from last year's roster while also signing tight end Jared Cook. Entering his age 40 season, this could be Brees' last chance to win his second Super Bowl.

The Giants made a controversial decision when they drafted Duke quarterback Daniel Jones with the sixth pick in the draft, even though they figure to keep Eli Manning as their starter this season. Jones never threw for 3,000 yards in college, but he will now be breathing down the neck of a Giants Super Bowl hero on what looks like a rebuilding team.

The Jets surprised many when they hired Gase after he was fired by the Dolphins, but the even more shocking move was the firing of GM Mike Maccagnan following the draft. Like he did in Miami, it looks from the outside like Gase gained leverage over the Jets organization. Of course, New York hopes the results this time around are better than they were in Miami.

Jon Gruden's return to football was rough last season, but few teams have been busier this offseason. Among the Raiders big moves were the hiring of former NFL Network analyst Mike Mayock to the GM post as well as big additions Antonio Brown, Tyrell Williams, Trent Brown and a bevy of draft picks. Despite a tough AFC West division, the Raiders expect to make a big improvement from 4-12.

Carson Wentz was the favorite to win the MVP in 2017 before suffering a season-ending knee injury late in the year. The injury delayed the start of his 2018 season, and he was inconsistent until suffering a back injury late last year. Philadelphia still expects Wentz to return to his MVP-level form this year after a somewhat disappointing 2018 season for the team.

The marriage between the Steelers and Antonio Brown was often rocky, but it reached the point of no return late last season when Brown sat out in Week 17. While JuJu Smith-Schuster has developed into a star early in his career, the team doesn't have a clear replacement for Brown's stats. It could take a full team effort, but the Steelers hope improving team chemistry will help lead to a rebound season.

Not many teams had worse luck than the 49ers last year, most notably losing Garoppolo to a torn ACL early in the year. With its signal-caller back and healthy and revamped defensive talent led by Dee Ford, Kwon Alexander and Nick Bosa, San Francisco has their sights set on the playoffs for the first time in a while.

Seattle's defense has undergone quite a two-year transition, losing most of the players who led the Seahawks' Super Bowl runs. This offseason was headlined by the losses of Frank Clark and Earl Thomas, and it remains to be seen if there is enough talent to support the run-heavy offense and return to the playoffs.

Jameis Winston had another disappointing season in 2018 and could be on his last leg in Tampa Bay now in the final year of his contract. Arians has done a great job in his past opportunities with the Colts and Cardinals, but it remains to be seen how much he will be able to help Winston.

After a nice start to his NFL career, Mariota has regressed over the last two seasons. He has combined to throw only 24 touchdowns with 23 interceptions in 29 games, and the Titans offense has yet to break out. While Tennessee gave him more support this offseason by signing Adam Humphries and drafting A.J. Brown, the team also added former Dolphins starter Ryan Tannehill to backup Mariota. If Mariota gets off to a slow start, it's not out of the realm of possibility that the Titans would turn to Tannehill.

Even after acquiring Case Keenum in the offseason, Washington drafted Ohio State quarterback Dwayne Haskins with the 15th-overall pick. Haskins has been the subject of a wide array of opinions regarding his NFL projectability, but he does provide the excitement that will sell tickets in Washington. After Alex Smith's unfortunate bad luck due to injury, the organization hopes to have better fortune with Haskins.
