By Sean Leahy, USA TODAY  • Training camp: Northern Arizona University, Flagstaff, Ariz. Fan access: Free, open to the public, 602-379-0101.  • Key changes: The NFC champs lost DE Antonio Smith in free agency to Houston, but second-year player Calais Campbell should be ready to assume his spot. They drafted RB Chris "Beanie" Wells with their first pick, which paved the way for the release of RB Edgerrin James. Free-agent CB Bryant McFadden should start.  • Key issues: WR Anquan Boldin's unhappiness with his contract has lingered since last season. Will his failure to get a new deal become a distraction? RB Tim Hightower didn't stake a claim to the starting role last season after supplanting James. Is Wells ready to assume the top job?  • Training camp: Falcons training facility, Flowery Branch, Ga. Fan access: Free, select practices open to the public, 770-965-3115.  • Key changes: They acquired TE Tony Gonzalez in a trade with the Chiefs. He could become a key weapon for second-year QB Matt Ryan. Defensive starters DT Grady Jackson, LBs Michael Boley and Keith Brooking and CB Domonique Foxworth left in free agency. They went defense-heavy in the draft, and DT Peria Jerry, their first-round pick, will get a chance to start in Jackson's old spot.  • Key issues: No one rushed more than Michael Turner's 376 attempts last season. The Falcons will start two new outside linebackers after the departures of Boley and Brooking. Free-agent pickup Mike Peterson will get one spot and third-year player Stephen Nicholas has a shot to win the other. Rookie William Moore will battle second-year player Thomas DeCoud for the starting strong safety spot.  • Training camp: Wofford College, Spartanburg, S.C. Fan access: Free, open to the public, 704-358-7000.  • Key changes: CB Ken Lucas is the only starter the Panthers aren't bringing back from the team that won the NFC South last year. DE Everette Brown, their top pick, was added as insurance in case franchised DE Julius Peppers didn't return. Peppers has signed his contract tender and is set to earn $16.7 million.  • Key issues: Were the six turnovers committed by QB Jake Delhomme in Carolina's playoff loss to Arizona just a hiccup? The Panthers must think so, because they gave Delhomme, 34, a five-year extension. Depth, particularly on the offensive line and at receiver beyond starters Steve Smith and Muhsin Muhammad, is a problem.  • Training camp: Olivet Nazarene University, Bourbonnais, Ill. Fan access: Free, open to the public, 847-295-6600  • Key changes: Jay Cutler will line up under center after the Bears traded a boatload of picks, including two first-rounders, to Denver for him. He'll play in front of an retooled offensive line, which added former Pro Bowl LT Orlando Pace. Head coach Lovie Smith will call the defensive plays this season, and imported ex-Lions coach Rod Marinelli to tutor the defensive line.  • Key issues: The Bears failed to add a top-flight receiver and believe that Devin Hester can step up and be Cutler's go-to guy. The defense, which fell from sixth to 22nd in sacks last season, needs to develop a stronger pass rush.  • Training camp: Alamodome, San Antonio. Fan access: Free, most practices open to the public, 972-556-9900.  • Key changes: Gone are several big-name players. The most notable subtraction is WR Terrell Owens, who was cut in March. Also leaving were CB Adam "Pacman" Jones, S Roy Williams, LB Zach Thomas, LB Greg Ellis and DT Tank Johnson. The Cowboys also lost DE Chris Canty in free agency, though they signed DE Igor Olshansky and LB Keith Brooking.  • Key issues: With Owens gone, can the other Roy Williams step into his role as Tony Romo's go-to receiver? Williams, who cost the Cowboys a package that included first- and third-round picks, caught just 19 passes in 10 games for Dallas last season. Romo will need to improve on his 5-10 record in December and January over the past three years.  • Training camp: Lions training facility, Allen Park, Mich. Fan access: Free, open to the public, 313-262-2882  • Key changes: Jim Schwartz's arrival as head coach, following the dismissal of Rod Marinelli, heads a total overhaul in Detroit. The Lions drafted QB Matthew Stafford with the first overall pick and TE Brandon Pettigrew with the 20th. Several veteran additions could step in as starters, including CB Philip Buchanon, DT Grady Jackson, LB Larry Foote and LB Julian Peterson.  • Key issues: Is a new coach and vastly different roster enough to wipe away the stain of the NFL's first 0-16 season? Stafford will compete with Daunte Culpepper for the starting spot.  • Training camp: St. Norbert College, De Pere, Wis. Fan access: Free, open to the public, 920-569-7500.  • Key changes: The biggest change will come in the adoption of new defensive coordinator Dom Capers' 3-4 alignment. They drafted DL B.J. Raji, who may fit at end, with the ninth overall pick and then got LB Clay Matthews with the 26th. Pro Bowl DE Aaron Kampman, who's had 37 sacks the past three seasons, is moving to outside linebacker.  • Key issues: Will Kampman, who has been quiet about his changing role, remain effective? And will there be other growing pains that emerge from the transition to 3-4 that coach Mike McCarthy acknowledged would be challenging? RT Allen Barbre will get a chance to fill the opening left by Mark Tauscher's departure.  • Training camp: Minnesota State University, Mankato, Minn. Fan access: Free, open to the public, 952-828-6500.  • Key changes: The biggest addition may still come, as QB Brett Favre has yet commit to ending his retirement and joining the team. If he doesn't, QB Sage Rosenfels, acquired from the Texans, will compete with Tarvaris Jackson for the starting spot. WR Percy Harvin, drafted with the 22nd overall pick, has the potential for game-breaking plays. John Sullivan likely takes over at center.  • Key issues: The Vikings need a stable hand at quarterback that can allow talented RB Adrian Peterson to shine. DTs Kevin Williams and Pat Williams (no relation) face a four-game suspension for use of a banned diuretic that is currently in litigation. Losing them would be a blow to a defense that ranked first against the rush the past three years.  • Training camp: Saints training facility, Metairie, La. Fan access: Free, most practices open, 504-733-0255.  • Key changes: They upgraded the secondary by drafting CB Malcolm Jenkins with the 14th overall pick and adding CB Jabari Greer and S Darren Sharper in free agency. They also added DEs Paul Spicer and Anthony Hargrove to add depth to a defensive line that was plagued by injuries and ineffectiveness.  • Key issues: Getting that defensive front to play at a higher level and generate consistent pressure will likely be a priority for Williams. But starting ends Will Smith and Charles Grant could face four-game suspensions for their use of a banned diuretic. The departure of Deuce McAllister leaves the rushing game in the hands of Pierre Thomas and Reggie Bush, who's been limited to 22 games in the past two seasons. Is Thomas ready to be an every-down back? Backup TE Billy Miller could step in if the Saints feel they're not getting enough out of Jeremy Shockey.  • Training camp: University at Albany, N.Y. Fan access: Free, open to the public, 201-935-8111.  • Key changes: The Giants are looking for a new No. 1 receiver after cutting ties to Plaxico Burress. They fortified their defense by signing DE Chris Canty, DT Rocky Bernard and LB Michael Boley. Bill Sheridan takes over as defensive coordinator after Steve Spagnuolo left to become the Rams' head coach. DE Osi Umenyiora returns to a formidable defensive line.  • Key issues: Will someone (Steve Smith? Domenik Hixon? first-round pick Hakeem Nicks?) emerge as the go-to receiver for Eli Manning? They lost a 1,000-yard back when Derrick Ward signed with the Bucs. Will Ahmad Bradshaw give them the same depth quality behind their other 1,000-yard back, Brandon Jacobs?  • Training camp: Lehigh University, Bethlehem, Pa. Fan access: Free, most practices open, 215-463-2500.  • Key changes: They overhauled Donovan McNabb's protection by trading for Pro Bowl LT Jason Peters and adding RG Stacy Andrews to play alongside brother Shawn, who's moving to tackle. Offensive reinforcements came in the draft in WR Jeremy Maclin and RB LeSean McCoy. Longtime S Brian Dawkins left as a free agent for Denver. They acquired CB Ellis Hobbs from New England.  • Key issues: How much time will Brian Westbrook need to get to 100% after undergoing right ankle surgery in June? Second-year S Quintin Demps must fill the shoes of the departed Dawkins. QB Donovan McNabb reworked the final two years of his contract. But how secure will he be?  • Training camp: Russell Training Center, Earth City, Mo. Fan access: Free, most practices open, 314-516-8852.  • Key changes: Former Giants defensive coordinator Steve Spagnuolo takes over a team that won just five games in the past two seasons. The offensive line has been rebuilt, with free-agent C Jason Brown coming on board, Alex Barron moving to left tackle to replace the departed Orlando Pace and No. 2 overall pick Jason likely moving in at right tackle. The release of WRs Torry Holt and Drew Bennett has left the Rams very young at receiver.  • Key issues: Where is the talent? Beyond RB Steven Jackson, it's hard to identify a Rams offensive playmaker who would be a certain starter on other teams (although second-year WR Donnie Avery shows promise). The Rams must be patient and wait for QB Marc Bulger to develop a rapport with the wideouts. The Rams have a nucleus of a promising defense with DE Chris Long and S O.J. Atogwe aided by the likes of free-agent S James Butler and former top pick Adam Carriker. But the calendar may flip again before the offense catches up.  • Training camp: DeBartolo Sports Center, Santa Clara, Calif. Fan access: Free through online registration, some practices open, 408-562-4949.  • Key changes: Getting WR Michael Crabtree with the 10th overall pick was a boost for a team that hasn't had a 1,000-yard receiver since Terrell Owens left after the 2003 season. Mike Singletary begins his first full season as head coach, after going 5-4 in relief of Mike Nolan last year. In free agency they added depth in WR Brandon Jones and CB Dre' Bly, who will challenge for a starting spot.  • Key issues: Who will start at quarterback? Shaun Hill, who finished the past two seasons as the starter, will compete in camp with 2005 No. 1 overall pick Alex Smith, who has played in seven games the past two years. How quickly Crabtree can contribute is in question, especially since March foot surgery limited his participation in spring drills.  • Training camp: Virginia Mason Athletic Center, Renton, Wash. Fan access: Free through online registration, some practices open, 888-635-4295.  • Key changes: Jim Mora takes over as coach after Mike Holmgren's 10-year run ended. The Seahawks, beset by injuries last year, especially at receiver, splurged in free agency by signing former Bengals WR T.J. Houshmandzadeh. And they drafted LB Aaron Curry with the fourth overall pick, adding him to a strong linebacking corps that includes Lofa Tatupu and LeRoy Hill. LB Julian Peterson was traded to Detroit. CB Ken Lucas, a cap casualty in Carolina, returns to Seattle and will likely claim a starting spot.  • Key issues: Staying healthy, especially on offense, is the key. QB Matt Hasselbeck, limited to seven games last year by a back injury, figures to be healthy when camp opens. Adding Houshmandzadeh to WRs Nate Burleson and Deion Branch makes for an impressive corps, provided the latter two are on the field. The offensive line, which lost all five starters last season, needs LT Walter Jones, 35, and LG Mike Wahle, 32, back to protect Hasselbeck. On defense, they need DE Patrick Kerney, who ended up on IR last year with a shoulder injury, back after April surgery to take bone chips out of his left elbow.  • Training camp: One Buccaneer Place, Tampa. Fan access: Free through online registration, some practices open, 813-870-2700  • Key changes: Raheem Morris, 32, takes the reins as head coach. He brought in Jim Bates to replace longtime defensive coordinator Monte Kiffin. Morris will have a new starting quarterback that emerges from the trio of veteran Luke McCown, free-agent pickup Byron Leftwich and first-round pick Josh Freeman. The Bucs added two big pieces to their offense when they signed RB Derrick Ward and traded for TE Kellen Winslow from the Browns. Gone is 11-time Pro Bowler Derrick Brooks, who had been with Tampa since 1995.  • Key issues: The Bucs have the makings of a talented offense (in Winslow, Ward, receiver Antonio Bryant and a strong line) if they can tie it together with the right quarterback. They certainly have options, and Morris hasn't picked a front-runner yet. The defensive line is transitioning from the speedy Tampa Two scheme to a more traditional 4-3. And they're trying to convert Jermaine Phillips, a safety since entering the league in 2002, into Brooks' replacement at outside linebacker.  • Training camp: Redskins Park, Ashburn, Va. Fan access: Free through online registration, all practices open, 703-726-7000.  • Key changes: The Redskins splurged in free agency, adding DT Albert Haynesworth to a deal worth a then-record $41M guaranteed and also netting G Derrick Dockery. Then they bolstered the pass rush more by drafting LB Brian Orakpo with the 13th pick.  • Key issues: How will QB Jason Campbell respond after the Redskins flirted with acquiring Jay Cutler and Mark Sanchez in the offseason? Entering his second season under in head coach Jim Zorn's offense, Campbell is playing for a new contract after the season. Haynesworth was the ultimate space-eater in Tennessee. Will his presence help improve a defense that had an NFC-low 24 sacks last year?  You share in the USA TODAY community, so please keep your comments smart and civil.
