Every NFL team's biggest question as training camp opens

While the additions of head coach Kliff Kingsbury and quarterback Kyler Murray should make Arizona's offense more creative, the team's success starts with the offensive line. It was a major source of its offensive struggles last season, but the Cardinals hope the additions of veterans Marcus Gilbert and J.R. Sweezy make a difference.

After a second consecutive disappointing season last year, the Falcons cleaned house in the offseason and fired all three of their coordinators. The good news on offense is that new offensive coordinator Dirk Koetter has experience working with Matt Ryan, while head coach Dan Quinn is expected to be more hands-on on the defensive side of the ball. For Quinn, this could be his last shot in Atlanta despite leading the team to the Super Bowl just three years ago.

The Ravens became the most run-heavy team in football last year when Lamar Jackson replaced Joe Flacco at quarterback, and they're expected to go all in on that plan after promoting Greg Roman to offensive coordinator and adding running backs Mark Ingram and rookie Justice Hill. In the pass-happy NFL, it remains to be seen whether running the ball 60-plus percent of the time can succeed in the long term.

Buffalo has followed a proven model of adding significant talent around its young quarterback, Josh Allen. Among the additions are center Mitch Morse, wide receivers John Brown and Cole Beasley, and rookies Cody Ford, Dawson Knox and Devin Singletary. The team did show some spark on offense late last season, but it remains to be seen how the new additions will mold with Allen.

Newton is expected to be ready for training camp despite major shoulder surgery. It's clear the Panthers are more concerned about Newton's health as he enters his age 30 season, as they drafted West Virginia quarterback Will Grier in the third round and also installed a short passing game under offensive coordinator Norv Turner last year to help prevent the hits that Newton was taking in the pocket. For a quarterback who welcomes contact as a runner, it remains to be seen how much the Panthers will allow Newton to be exposed this year.

Bears fans don't need to be reminded of the way their 2018 season ended: with a Cody Parkey missed field goal in the playoffs. Chicago has searched for a new kicker in the offseason but hasn't made a splash with any well-known additions. Elliott Fry and Eddy Pineiro enter the offseason in competition, but the Bears could still add from outside the organization. 

Cincinnati got younger on defense this offseason after ranking last in yards allowed and allowing more than 28 points per game in 2018. The most significant change was to the coaching staff, with new head coach Zac Taylor and defensive coordinator Lou Anarumo. The team still has a strong defensive line, but the development behind them will be key.

Cleveland won the offseason on paper, with impact additions like Odell Beckham Jr., Olivier Vernon and Sheldon Richardson. The Browns are an en vogue pick to win the AFC North this season over the Steelers and Ravens, but it still remains to be seen if they can continue last year's momentum with Freddie Kitchens getting his first shot as a head coach.

Prescott has shown some inconsistency over the last two seasons, but he played markedly better after the Cowboys acquired Amari Cooper last season. While efficient, Prescott still hasn't put up huge numbers in his three NFL seasons. He might need to break out for the Cowboys to become a Super Bowl contender, and there also remain questions about his post-rookie contract in Dallas.

Finding a quarterback has been a major problem for Denver since Peyton Manning's retirement. Former first-round pick Paxton Lynch was a bust, and Case Keenum failed to really help last year. The team has multiple options this year after trading for Joe Flacco and drafting Drew Lock in the second round. Of course Flacco has been mediocre recently with the Ravens, and Lock could probably use some development time. Flacco is likely to be the early starter, but he has a rookie breathing down his neck for the second straight year.

Detroit's offense was its strength just two years ago, but it was out of sorts last season before firing coordinator Jim Bob Cooter. Former Seahawks coordinator Darrell Bevell has taken the reins and has plenty of talent to work with, including Matthew Stafford, Kerryon Johnson, Marvin Jones and Kenny Golladay. His success or failure could ultimately determine whether head coach Matt Patricia is still around in 2020.

Head coach Mike McCarthy was the scapegoat when the Packer struggled last season. The team has brought in a more creative offensive mind in LaFleur this year but didn't make many changes in the offensive personnel. Aaron Rodgers is entering his age 36 season, and the organization only has so much time left with the star quarterback. LaFleur's impact could say as much about him as it does about Rodgers and McCarthy.

Quarterback Deshaun Watson took a league-high 62 sacks last season, hardly a good trend as he returned from a torn ACL. Houston has failed to adequately address the offensive line in recent seasons but hopes it has found the answers with first-round pick Tytus Howard and second-round pick Max Scharping. Those rookies could make the difference in the team's 2019 success.

The Colts offensive improvement got much of the press last year, but their defense was the big surprise. It ranked 10th in the league with 21.5 points allowed per game and saw several breakout seasons, including from rookie Darius Leonard. The team spent most of this year's draft on defense, and the addition of veteran pass rusher Justin Houston could create a big impact. The Colts are trying to prevent second-year regression under coordinator Matt Eberflus, and they could be Super Bowl contenders if they succeed.

Jaguars fans finally got their wish this offseason after the team moved on from Blake Bortles and signed Nick Foles. Foles was the Super Bowl MVP two years ago and showed flashes of brilliance in Philly, but the weapons around him in Jacksonville aren't quite as impressive. The talent on defense remains elite, but there are still questions about how much impact Foles will have at quarterback.

The unfortunate off-field situation surrounding Tyreek Hill has overshadowed a busy offseason for the Chiefs front office, which made several high-impact moves as it tries to fix last year's issues. Hill is expected to report to training camp, but a suspension from the NFL is a strong possibility. Kansas City added insurance for Hill by drafting speedster Mecole Hardman in the second round, but losing Hill for any amount of time will certainly hurt the team.

Gordon's agent recently announced that the running back won't report to training camp without a new contract, and a holdout that goes into the regular season is also a possibility. Gordon proved himself to be a game changer last season with 5.1 yards per carry, but he's also missed time to injury in three of his four seasons. This situation is a major risk for L.A., but it might bite the bullet and give into Gordon's demands with quarterback Philip Rivers approaching his final years on the field.

Gurley sat late last season and saw his playing time curtailed in the playoffs due to what we learned was an arthritic knee. The offense wasn't quite the same without him, and re-signing Malcolm Brown and drafting Darrell Henderson in the third round reflects the team's concern. Despite that insurance, the Rams could have a tough time matching last year's success without a healthy Gurley.

Miami looks to be in rebuild mode but has a pair of intriguing quarterback options in Ryan Fitzpatrick and second-year player Josh Rosen. Fitzpatrick has been a good starter in spurts during his career, while Rosen showed enough promise in college to garner the 10th-overall draft pick last year. The starting job is up for grabs entering training camp, and it's unclear how it will play out.

While Kirk Cousins' failure to help the Vikings offense got much of the blame for Minnesota's disappointing 2018 season, the defense shares in the blame. After allowing a league-best 15.8 points per contest in 2017, the Vikings allowed more than 21 points last year. There remains more than enough talent for the defense to rebound, but it's easier said than done.

Tom Brady was at his best when it counted in the playoffs last year, winning his sixth Super Bowl. The offseason has still been one of major changes for the Patriots, but there remains trust in head coach Bill Belichick after so many years of success. Still, the loss of Rob Gronkowski can't be understated, and the team is trying to make due with the likes of rookie N'Keal Harry, veteran Demaryius Thomas and tight ends Matt LaCosse and Benjamin Watson in an offense that isn't easy for new players to learn. Brady does still have Julian Edelman, if nothing else.

The Saints and their fans are still fuming over a pass interference no-call in the NFC championship that cost the team a trip to the Super Bowl. New Orleans remains loaded with talent, but we could be entering Drew Brees' final season at age 40. For all the team's success with Brees and head coach Sean Payton, the team has still advanced to only one Super Bowl in 13 seasons, and anything short of another Super Bowl berth this year will be considered a disappointment.

Analysts have been critical of GM Dave Gettleman's offseason, allowing safety Landon Collins to walk in free agency, trading Odell Beckham Jr. and Olivier Vernon and drafting Duke quarterback Daniel Jones sixth overall. The Giants have had losing seasons in five of the last six years, and it's clear the talent on the field isn't as impressive as last year. With Eli Manning approaching the end of his career at age 38, the 2019 season could get ugly.

It's been an interesting offseason for the Jets, to say the least, starting with the hiring of Gase after he failed to win consistently in Miami. He's tasked with developing Sam Darnold and has some help with Le'Veon Bell, Jamison Crowder and several offensive line acquisitions. Fans have reason to expect a big step forward this season, and Gase will be blamed if it doesn't happen.

The Raiders made several impressive offensive additions this offseason, led by Antonio Brown, but their biggest issue last season remains a big question mark heading into this season. Oakland traded Khalil Mack prior to Week 1 last year and recorded a pitiful 13 sacks all of last year. For all the changes, the Raiders aren't going anywhere without putting more pressure on the quarterback, but their only major pass-rush addition was first-round pick Clelin Ferrell.

Wentz's first three NFL seasons have featured some terrific play but also major injuries over the last two seasons. He suffered a torn ACL late in the 2017 season, and a back injury ended his 2018 season early. Now without Nick Foles, the Eagles can't afford for Wentz to miss more time this year.

Brown became a distraction for the Steelers last season, but his production won't be easy to replace. He reached 1,200 yards receiving for the sixth straight year and also led the league with 15 receiving scores in 2018. Pittsburgh signed veteran Donte Moncrief and drafted Diontae Johnson in the third round, but replacing Brown's stats and impact will be difficult.

Garoppolo has a clean bill of health after suffering a torn ACL early last season, but it still remains to be seen how good he can be as the starting quarterback. While he went 5-0 in his 49ers debut late in 2017, Garoppolo went 1-2 as the starter early last year and has thrown eight picks in nine games with the team. Kyle Shanahan is a master play caller and schemer, but the team will only go as far as Garoppolo can take it.

The defensive overhaul for Seattle continues, now without star defensive end Frank Clark. Clark's elite pass rushing ability helped smooth out some of the issues in the secondary last season, but now the team is counting on veteran Ezekiel Ansah and first-round pick L.J. Collier to pick up the slack. If it is unable to match last year's pass rush, the offense could be forced to throw more than it would like.

Jameis Winston has had back-to-back disappointing seasons and is entering the final year of his contract in Tampa Bay. New head coach Bruce Arians was brought on to fix Winston, and he still has some impressive weapons despite losing DeSean Jackson and Adam Humphries from last year's team. If Winston fails to improve this year, the Bucs could draft another quarterback next year.

The Titans haven't gotten much production at quarterback over the last two seasons from Mariota, as he's thrown only 24 touchdowns in 29 games and has averaged less than 200 yards passing per game. Even with a great running game, the Titans need more from their quarterback to be true contenders. Mariota is entering the final year of his rookie deal and has an adequate backup in Ryan Tannehill if he falters this year.

Washington thought it had quarterback figured out after trading for Alex Smith last offseason, but his career is in doubt after a terrible leg injury. The team acquired Case Keenum and drafted Dwayne Haskins in the first round this year, and the Week 1 starter is very much a question mark, with Colt McCoy also figuring into the race. The job should go to Haskins eventually, but it remains to be seen if he's ready to play now.
