AFC WEST

Denver

Camp location: Englewood, Colo.

Hello: After Peyton Manning retired and Brock Osweiler signed with Houston, the Broncos made a trade with Philadelphia for quarterback Mark Sanchez and took Memphis State's Paxton Lynch in the first round.

Goodbye: Lots of departures from Denver's Super Bowl-winning team, among them defensive tackle Malik Jackson, linebacker Danny Trevathan, safety David Bruton Jr. and tight end Owen Daniels.

Big questions: With Manning and Osweiler gone, how does Coach Gary Kubiak manage the quarterback situation? Linebacker Von Miller just got the biggest non-quarterback contract in NFL history. Can he keep the defense rolling despite all the departures?

Kansas City

Camp location: St. Joseph, Mo.

Hello: It wasn't a splashy, headline-stealing move, but the Chiefs picked up a rock-solid tackle in Mitchell Schwartz, a starter in Cleveland the last four seasons.

Goodbye: Safeties Husain Abdullah and Tyvon Branch are gone, along with defensive tackle Mike DeVito and backup quarterback Chase Daniel.

Big question: The Chiefs made an incredible U-turn last season, starting 1-5 before winning 10 in a row and making the playoffs. Now, they're getting back injured stars Jamaal Charles, Justin Houston and Tamba Hali. Are they poised to go deep into the playoffs this year, or is it just more warning-track power?

Oakland

Camp location: Napa, Calif.

Hello: The Raiders have beefed up their already strong defense with the addition of linebacker Bruce Irvin (formerly of Seattle), cornerback Sean Smith (Kansas City) and safety Reggie Nelson (Cincinnati).

Goodbye: Safety Charles Woodson retired _ next stop, Canton, Ohio _ and the Raiders also bid farewell to defensive end Justin Tuck and linebacker Curtis Lofton.

Big question: The Raiders have gone 13 consecutive seasons without making the playoffs, or even recording a winning record. With their promising roster _ and young stars in quarterback Derek Carr, receiver Amari Cooper and defensive end Khalil Mack _ can they finally end that drought?

San Diego

Camp location: San Diego.

Hello: The Chargers fortified their trenches by adding center Matt Slauson, nose tackle Brandon Mebane and rookie defensive end Joey Bosa.

Goodbye: Gone are safety Eric Weddle and receiver Malcom Floyd, players synonymous with the Chargers. The team will also be looking to replace the production of tight end Ladarius Green.

Big questions: Coming off a 4-12 season, and having missed the playoffs for the fifth time in six seasons, can the Chargers regain their footing in the twilight of the Philip Rivers era? And what about that lingering threat to relocate to Los Angeles?

AFC EAST

Buffalo

Camp location: Pittsford, N.Y.

Hello: The Bills used their first three picks on defensive players: linebackers Shaq Lawson and Reggie Ragland and tackle Adolphus Washington. All could be starting by midseason.

Goodbye: In March, the Bills parted ways with defensive end Mario Williams after four seasons, releasing the former No. 1 overall pick who began his career in Houston.

Big questions: How will the club work out the contract situations of two pivotal players, cornerback Stephon Gilmore and quarterback Tyrod Taylor? Does Coach Rex Ryan have to make the playoffs to keep his job?

Miami

Camp location: Davie, Fla.

Hello: Rookie tackle Laremy Tunsil, who slid from the top of the draft to No. 13 because of character concerns, will look to solidify an offensive line that has yielded an NFL-high 184 sacks since 2012.

Goodbye: In deciding to keep Cameron Wake, the Dolphins let defensive end Olivier Vernon walk out the door. The New York Giants promptly signed Vernon to a five-year deal worth $85 million, the most lucrative in NFL history for an edge rusher.

Big question: Can new Coach Adam Gase turn around a franchise ranked 25th in offense and 26th in defense last season?

New England

Camp location: Foxborough, Mass.

Hello: Defensive end Chris Long, who played eight seasons in St. Louis, fits the mold of an aging star who is reinvigorated in Bill Belichick's system. With Rob Gronkowski and the just-added Martellus Bennett, the Patriots' collection of receiving tight ends is almost unfair.

Goodbye: The Patriots needed to add Long, seeing as they traded defensive end Chandler Jones to Arizona, bidding farewell to a player who had a career-high 12{ sacks last season.

Big question: How will third-year quarterback Jimmy Garoppolo perform in the first four games, while Tom Brady serves his Deflategate suspension?

New York Jets

Camp location: Florham Park, N.J.

Hello: Running back Matt Forte, who rolled up an NFL-high 12,718 yards of all-purpose offense the past eight seasons in Chicago, joined the Jets in free agency. The team also acquired tackle Ryan Clady in a trade with Denver.

Goodbye: Forte became a priority when the Jets lost running back Chris Ivory to Jacksonville. Cornerback Antonio Cromartie was released after his second tour of duty with the club.

Big question: Can the Jets work out their quarterback situation? The Ryan Fitzpatrick negotiations have dragged on for months, and the Geno Smith fallback plan is less than enticing.

AFC NORTH

Baltimore

Camp location: Owings Mills, Md.

Hello: Safety Eric Weddle, for years the face of San Diego's defense, will now patrol the back end of Baltimore's defense. He's a two-time All-Pro and the Chargers' defensive player of the year in three of the past five seasons.

Goodbye: Left tackle Eugene Monroe was released by the Ravens in June and decided a month later to retire. Rookie Ronnie Stanley, the No. 6 overall pick, is slated to step into that role.

Big question: How well will Joe Flacco recover from reconstructive knee surgery, and can he do enough to return the Ravens to their Super Bowl glory?

Cleveland

Camp location: Berea, Ohio

Hello: New Coach Hue Jackson is overseeing a fluid quarterback situation, with Josh McCown back but competing for the starting job with Robert Griffin III, whose once promising career fizzled in Washington, and rookie Cody Kessler.

Goodbye: The Browns cut ties with the troubled Johnny Manziel and parted ways with some fixtures in center Alex Mack, tackle Mitchell Schwartz and safety Donte Whitner.

Big question: Can Jackson, a quarterback specialist, work his magic and cobble together a solution at the most important position? The club has cycled through 24 starting quarterbacks since relaunching as an expansion franchise in 1999.

Cincinnati

Camp location: Cincinnati.

Hello: The Bengals signed a big-name veteran on both sides of the ball with the same-day pickups of receiver Brandon LaFell and linebacker Karlos Dansby. First-round pick William Jackson III could make a splash at cornerback.

Goodbye: Gone are receivers Mohamed Sanu (Atlanta) and Marvin Jones (Detroit), both of whom are expected to have bigger roles with their new teams. The addition of LaFell helps salve that sting.

Big question: Coming off the best season of his career, can quarterback Andy Dalton win a playoff game and maybe even make an MVP push?

Pittsburgh

Camp location: Latrobe, Pa.

Hello: The homegrown Steelers don't typically wade too deep in the free-agent pool, so it's noteworthy they grabbed tight end Ladarius Green, who was a good complement to Antonio Gates in San Diego.

Goodbye: Heath Miller retired in February as the club's all-time leader in receptions (592), yards receiving (6,569) and touchdowns (45) by a tight end.

Big questions: With all their offensive firepower, are the Ben Roethlisberger-led Steelers on their way to record-breaking numbers? What will the availability of Le'Veon Bell be, considering the looming threat of suspension?

AFC SOUTH

Houston

Camp location: Houston.

Hello: The Texans paid big bucks ($18 million per year) to lure quarterback Brock Osweiler from Denver, and now they're looking to reap the dividends. He'll be joined by running back Lamar Miller, who averaged a robust 4.8 yards per carry during the past two seasons in Miami.

Goodbye: Quarterback Brian Hoyer (Chicago) is gone, and so is running back Arian Foster (Miami).

Big questions: The Texans need to build an offense to complement their strong defense, but is Osweiler up to the challenge? How quickly can three-time NFL defensive player of the year J.J. Watt recover from back surgery to return?

Indianapolis

Camp location: Anderson, Ind.

Hello: The Colts picked four offensive linemen in this spring's draft, including first-round center Ryan Kelly, expected to anchor that line. The Alabama standout won the Rimington Award last season as the nation's top college center.

Goodbye: Quarterback Matt Hasselbeck (retired) and tight end Coby Fleener (New Orleans) are no longer with the Colts. Quarterbacks coach Clyde Christensen and defensive coordinator Greg Manusky are gone too.

Big question: After an abysmal season in which he missed nine games — and his team missed the playoffs for just the second time since 2002 — will quarterback Andrew Luck bounce back strong?

Jacksonville

Camp location: Jacksonville, Fla.

Hello: The Jaguars made a big commitment to stepping up their defense, opening their wallet to acquire tackle Malik Jackson and cornerback Prince Amukamara, as well as draft cornerback Jalen Ramsey and linebacker Myles Jack.

Goodbye: Gone are defensive end Chris Clemons and center Stefen Wisniewski.

Big questions: Although they improved on offense, the Jaguars were dragged down by their defense last season, ranking near the bottom in virtually every defensive category. Will all the personnel adjustments change that? How much more time does Coach Gus Bradley have, seeing as he's 12-36 in his three seasons?

Tennessee

Camp location: Nashville.

Hello: The Titans were 25th in rushing offense last season. They addressed that by trading for running back DeMarco Murray, who played one season with Philadelphia after winning the 2014 rushing title with Dallas.

Goodbye: Safety Michael Griffin was released after nine seasons. The former first-round pick out of Texas who has 25 career interceptions had lost a step at age 31, and was a liability on the back end of Tennessee's defense.

Big question: With an improved offensive line, and more horsepower in the backfield with Murray and rookie Derrick Henry, can Marcus Mariota build on his strong debut?
