For all the buzz around the other teams in the division, it gets easily overlooked that the Kansas City Chiefs are the reigning division champions, coming off a 12-4 record last year. But the question around the Chiefs is whether this team can take that next step forward and make a deep postseason run, or will they take a step back given all the questions they have on offense. The defense shouldn’t miss a beat, with as many as five Pro Bowl-caliber players on defense — cornerback Marcus Peters, safety Eric Berry, outside linebackers Tamba Hali and Justin Houston, and inside linebacker Derrick Johnson — along with an emerging stud in defensive end Chris Jones, and a very solid free agent acquisition in defensive tackle Bennie Logan. But the offense, which ranked in the bottom half of the league in total yards (20th) and passing yards (19th) per game, has plenty of questions left to be answered this season. How does the Chiefs selection of quarterback Patrick Mahomes with their top pick in the 2017 NFL Draft affect the play of quarterback Alex Smith, whom Mahomes was drafted to replace? How will the Chiefs running game fare with rookie Kareem Hunt (the team’s 3rd round pick) taking over for Spencer Ware, who was lost to a season-ending injury in the preseason? And does the team have any receiver they can reliably trust, outside of Tyreek Hill, after releasing Jeremy Maclin in the offseason? It’s going to take every ounce of guidance that head coach Andy Reid can muster to get this team to the heights that many believe they’re capable of, given the aforementioned challenges.

Nobody will question whether the Oakland Raiders will have the capability to move the football and score a lot of points with their offense. Derek Carr is one of the most exciting young quarterbacks in the league. Michael Crabtree and Amari Cooper are one of the most productive wide receiver duos in the NFL. The offensive line doesn’t get quite as much credit as it should, but it’s easily one of the three or four best units in the league. The unretired Marshawn Lynch should, at least in theory, provide some punch to the running game. No, the thing that everyone will question is whether Oakland can stop anyone from moving the football up and down the field against their defense, which finished last season giving up the seventh-most yards per game in the league last year. While the team used six of their nine draft picks in the 2017 NFL Draft on defensive players, the unit remains largely the same as the group from last year. Will the continuity, coupled with the addition of John Pagano as the Assistant Head Coach — Defense, be enough to get a serviceable performance from that side of the ball?

Less than two years removed from winning the Super Bowl, the Denver Broncos now find themselves amidst a major transition in the team’s direction. Gone are surefire Hall of Fame quarterback Peyton Manning, head coach Gary Kubiak, and venerated defensive coordinator Wade Phillips. New head coach Vance Joseph seemingly has his hands full, with a team that has a bevy of talented players, but a roster that’s been slowly depleted because of free agent defections and ineffective draft classes. The team’s calling card will remain its defense, considering the team still has the best pure edge rusher in the NFL (Von Miller) and the best pair of cornerbacks in the league (Aqib Talib and Chris Harris Jr.), but it may not be safe to assume they’ll be just as dominant has they have been in years past, considering how many key veterans they’ve lost from that group in recent years — most recently safety TJ Ward, whom the team released just days before the 2017 roster cut down date. On offense, the team still has yet to find it’s answer at quarterback, as they’ll continue to start Trevor Siemian under center, behind an offensive line that still has plenty of questions of its own.

The Chargers, who officially moved to Los Angeles this past offseason, will also have a new head coach along with a new home town. After parting ways with Mike McCoy, they brought in Anthony Lynn — the former interim head coach of the Buffalo Bills — as the new lead man, along with Gus Bradley as the new defensive coordinator. Lynn helped guide the Bills to the top-ranked rushing offense in the NFL in 2016, which only bodes well for running back Melvin Gordon, who enjoyed a breakout season of his own last year. On defense, Bradley will oversee a defense featuring breakout edge rusher Joey Bosa — the Defensive Rookie of the Year last year (voted by his peers) — and Melvin Ingram, along with cornerbacks Jason Verrett and Casey Hayward (the latter of whom led the NFL in interceptions last year). With Philip Rivers under center, the return of Keenan Allen at wide receiver, and second year tight end Hunter Henry emerging as yet another red zone weapon, the Chargers could be the biggest wildcard of this division, and a darkhorse playoff contender.

The story of the NFC West for the 2017-2018 season doesn’t really appear to be any different than the story we’ve seen in recent years: there are two teams in the division with legitimate aspirations of a deep playoff run, and then two teams that are still mired in a prolonged rebuilding process.

At the start of the season, it’s really hard to see anyone other than the Seattle Seahawks being the favorite to win the division crown. While the team sputtered to a 6-4-1 record over its last 11 games last year, they were decimated by injuries to so many key players. Even from a purely mathematical standpoint, it’s difficult for a team to endure that level of injury issues for yet another season. In doing his part to stay healthy through the course of the season, Russell Wilson came into training camp this year in the best shape of his life, working with celebrity nutritionist Dr. Philip Goglia in the offseason, losing 10lbs of weight and dropping his body fat by 6%. With no real superstud at running back — the team will cobble together a ground game featuring Green Bay Packers castoff Eddie Lacy, incumbent Thomas Rawls, and 2016 draft picks C.J. Prosise and Alex Collins — this offense really belongs to Wilson now. It’s much more about him running the show, throwing the football to Doug Baldwin, Tyler Lockett, Jermaine Kearse, Paul Richardson, and tight end Jimmy Graham. If the patchwork offensive line can simply give him any time to actually get the football out, he could be poised for an MVP-caliber season. And, of course, you can’t talk about the Seahawks without mentioning the defense. The unit will return nine of 11 starters, including defensive backbone Earl Thomas, meaning it should once again be as stout as we’ve come to know it in recent years.

Enduring an injury-riddled season in 2016 themselves, the Arizona Cardinals are looking to rebound closer to the form which saw them win an NFL-high 13 games in 2015. The biggest question for the Cardinals — along the lines of staying healthy — will be whether Carson Palmer’s arm can hold up for all 16 games, especially in an offense that demands a lot of vertical throws. Palmer has shown a penchant in recent years for starting out the season hot, but demonstrating arm fatigue as the year goes on. Of course, the latter the could be mitigated as the team begins to rely more on superstar running back David Johnson, whose combined 2,118 yards from scrimmage last year was second most in the NFL. Johnson’s ability as a running back and pass catcher make him one of the most dangerous weapons in the NFL, and will likely make him the focal point of a somewhat aging Cardinals offense. Arizona’s defense faces questions of their own around health and personnel, especially as they’re looking for the return of a healthy Tyrann Mathieu — who finished last season on injured reserve for the third time in four years — and to overcome the loss of defensive lineman Calais Campbell. However, Arizona has done an excellent job in “restocking the cupboard” on defense with young talent, starting with defensive tackle Robert Nkemdiche (their top pick in the 2016 NFL Draft), linebacker Haason Reddick (taken with their first round pick in the 2017 NFL Draft) and safety Budda Baker (their second round pick in the 2017 NFL Draft). There are still plenty of core players left on this team to lead them to one last deep playoff run, if things can finally break right for them.

During an episode of HBO’s Hard Knocks, (now former) head coach Jeff Fisher of the Los Angeles Rams chastised his team for resembling a football team destined for a 7-9 record. Little did Fisher realize that his team would be so lucky as to finish with a 7-9 record. The Rams finished a 4-12 record at season’s end, and Fisher didn’t even make it through the season before he was dismissed from his position (which many saw as long-overdue move). As his replacement, the Rams went in the total opposite direction, hiring offensive wunderkind Sean McVay — the former offensive coordinator of the Washington Redskins — and making him the youngest head coach in NFL history (he was officially hired just days before his 31st birthday). McVay’s primary responsibility will be to rectify all the damage that Fisher and his staff did to quarterback Jared Goff, the first overall pick in the 2016 NFL Draft. Meanwhile, McVay smartly hired defensive guru Wade Phillips, the latter of whom is only two years away from overseeing a defense that led its team to a Super Bowl victory (in Denver). Supposedly, the early whispers from the new regime are filled with glowing optimism, and everything you hear out of Los Angeles is that the player recognize what a difference in experience, leadership, and intellectual horsepower the new coaching staff has already brought. However, this roster still has major holes to fill — mostly on offense — before it can consider itself a contender in this division.

Rounding out the NFC West is the San Francisco 49ers, who underwent a much-needed housecleaning of their own last season, dismissing long time General Manager Trent Baalke and embattled head coach Chip Kelly. In their place will be new head coach Kyle Shanahan, fresh off leading the Atlanta Falcons to one of the most prolific offenses in NFL history, and new General Manager John Lynch, a surprise hire who lobbied Shanahan for the unorthodox opportunity of jumping straight from the broadcast booth to being the man in charge of a team’s front office. The two of them went to work adding numerous players to a roster that was badly in need of a talent infusion all over the board. At quarterback, journeymen Brian Hoyer and Matt Barkley will vie for the team’s starting job in the near future, but it wouldn’t be the slightest bit surprising to see them them address the position with one of their picks in the 2018 NFL Draft (which looks to have a quarterback class absolutely loaded with talent). Early on, they’ll look to the defense to keep them in games, after spending a first round pick on a defensive lineman — Soloman Thomas from Stanford University — for the third year in a row, and then trading up into the latter part of the first round to select linebacker Rueben Foster from the University of Alabama. The defense has some really intriguing players in pass rushing specialist Elvis Dumvervil, stalwart linebacker NaVorro Bowman, free safety Jimmy Ward, and defensive linemen DeForest Buckner and Arik Armstead (their first round picks in 2016 and 2015 respectively). But, with a much-needed roster turnover taking place over the long-term, this team is still years away from being ready to make any real noise in the division.
