Post columnist Steve Serby breaks down each team and every division in the NFC as part of our 2019 NFL preview:

1. Los Angeles Rams

Coach: Sean McVay

2018 record: 13-3

O/U wins: 10 ¹/₂

Key additions: FS Eric Weddle, OLB Clay Matthews, QB Blake Bortles, S Taylor Rapp, RB Darrell Henderson.

Key losses: S Lamarcus Joyner, OG Rodger Saffold, DT Ndamukong Suh, ILB Mark Barron

First-and-goal: McVay has been a godsend for Jared Goff, Super Bowl XLIII notwithstanding. Cooper Kupp returning from his torn ACL gives Goff a quality receiving triumvirate with Robert Woods and Brandin Cooks. LT Andrew Whitworth feels better than ever with his 38th birthday in December. Go ahead, try to block Aaron Donald. Pro Bowl CBs Aqib Talib and Marcus Peters are in the final year of their contracts. Veterans S Eric Weddle and LB Clay Matthews add savvy and leadership. Special teams coach John Fassel is fearless and innovative. The kicking game is in good hands — feet, actually — with PK Greg “The Leg” Zuerlein and Johnny Hekker.

Fourth-and-long: How diminished will RB Todd Gurley (knee) truly be? Can Michael Brown and rookie Darrell Henderson ride to the rescue the way C.J. Anderson did? Can Goff prove he is more than a system quarterback? Can inexperienced G Joseph Noteboom replace Rodger Saffold? Can inexperienced C Brian Allen replace Joseph Sullivan?

Serby Says: 10-6. But how much of a Super Bowl hangover will there be?

2. Seattle Seahawks

Coach: Pete Carroll

2018 record: 10-6

O/U wins: 8 ¹/₂

Key additions: G Mike Iupati, PK Jason Myers, WR DK Metcalf

Key losses: FS Earl Thomas, WR Doug Baldwin, CB Justin Coleman, G JR Sweezy, K Sebastian Janikowski, RB Mike Davis, DT Shamar Stephen

First-and-goal: Russell Wilson is a winner, case closed. A $140 million winner. RBs Chris Carson and Rashaad Penny form a bludgeoning 1-2 hammer for Carroll’s No. 1 rushing attack. LT Duane Brown anchors an O-line that is no longer an Achilles’ heel. Big-play WR Tyler Lockett (16.9 yards per catch) is counted on to mitigate the retirement of Doug Baldwin. As is rookie DK Metcalf, who looks like Tarzan but didn’t play like Jane this summer. TE Will Dissly, back from a knee injury, could be a red-zone weapon. Trade for DE Jadeveon Clowney gives Hawks replacement for Frank Clark. Elite $54 million LB Bobby Wagner has his sights set on an eighth straight 100-plus tackle season. Only a knee injury kept LB K.J. Wright from his fifth consecutive 100-plus tackle season. The Jets would love to have Pro Bowl PK Jason Myers back right about now.

Fourth-and-long: First-rounder L.J. Collier, who missed training camp with a high ankle sprain, has to help a defensive line that loses DT Jarran Reed to a six-game suspension and is waiting for DE Ziggy Ansah to move past his shoulder surgery. The Legion of Boom seems like a distant memory.

Serby Says: 9-7. Carroll has notched double-digit wins in six of his last seven seasons.

3. San Francisco 49ers

Coach: Kyle Shanahan

2018 record: 4-12

O/U wins: 8 ¹/₂

Key additions: EDGE Dee Ford, CB Jason Verrett, ILB Kwon Alexander, RB Tevin Coleman, EDGE Nick Bosa, WR Deebo Samuel, WR Jalen Hurd

Key losses: WR Pierre Garcon, EDGE Cassius Marsh, DT Earl Mitchell

First-and-long: Jimmy Garoppolo looked rusty in training camp, for whatever that’s worth. Lots of pressure on him after eight NFL starts, but at least he has Shanahan on his side. Dual threat RB Tevin Coleman reunited with Shanahan to add explosiveness and Matt Breida can spell him. TE George Kittle was an 88-catch, 1,377-yard revelation last season. Rookie WR Deebo Samuel is the real deal. OLB Dee Ford and first-rounder Nick Bosa bring the heat on the wide-nine defense alongside DT DeForest Buckner. Athletic Kwon Alexander ($54 million) joins Fred Warner on a promising linebacker corps. PK Robbie Gould earned an extension after going 33-for-34 on FGs.

Fourth-and-long: CB Richard Sherman can still play, but there is no trustworthy bookend. Two INTs from the secondary? Might as well have given Bagel Boss Guy a shot. Maybe injury-prone CB Jason Verrett can stay on the field. Guards Mike Person and Laken Tomlinson are question marks. WR Dante Pettis had a shaky summer. Special teams, which allowed 24.5 yards per kickoff return, are pedestrian.

Serby Says: 8-8. What if Jimmy GQ isn’t dressed to kill?

4. Arizona Cardinals

Coach: Kliff Kingsbury

2018 record: 3-13

O/U wins: 5

Key Additions: QB Kyler Murray, G J.R. Sweezy, T Marcus Gilbert, WR Michael Crabtree, WR KeeSean Johnson, WR Andy Isabella, TE Charles Clay, CB Byron Murphy, DE Zach Allen

Key losses: QB Josh Rosen, G Mike Iupati, WR J.J. Nelson, TE Jermaine Gresham

First-and-goal: Well, there’s 5-foot-10 Kyler Murray, who will be fun to watch. And there’s ageless WR Larry Fitzgerald. And there’s dual threat RB David Johnson, who should be rejuvenated after two years of frustration. Speedy second-year slot receiver Christian Kirk has a developing chemistry with Murray. Murray can hide behind RT Marcus Gilbert. Terrell Suggs, the league’s best 36-year-old pass rusher, becomes the league’s best 37-year-old pass rusher on Oct. 11 opposite Chandler Jones (77 sacks over seven seasons) — why did Rex Ryan like Quinton Coples better than him again? ILB Jordan Hicks ($36 million) should make an impact if he can stay healthy. Punter Andy Lee is a stud. Thankfully.

Fourth-and-long: Elite CB Patrick Peterson serves a six-game suspension and CB Robert Alford has a foot injury. Best of luck to rookie Byron Murphy. Rookie coach Kingsbury and his Air Raid offense are in for a rude awakening. The O-line surrendered 52 sacks last season and G Mike Iupati is now a Seahawk. Richard Sherman can’t wait to cover Michael Crabtree and rant about it afterward. PK Zane Gonzalez has missed four of 37 PATs. Anyone have Carli Lloyd’s cell?

Serby Says: 3-13. Murray will yearn for the days when he was 42-0 at Allen High School.
