Welcome to the weekly Fantasy Notebook, the must-stop spot for keeping your finger on the pulse of Fantasy Nation. NFL news and developments drive fantasy values. The Notebook is here to keep you in the loop on all of it throughout the season -- and into the offseason.
And So It Begins
Well, the Seahawks' win over the Patriots on Wednesday night makes it official.
The NFL season has officially begun, which means we're (mostly) done drafting, and we've moved on to projecting weekly outcomes and setting rankings to help make lineup decisions that actually count.
Making those calls might be the most challenging part of the entire fantasy football process.
It's even harder to open the season.
We have last year's offensive and defensive numbers, offseason personnel changes, coaching changes, and preseason clues -- but zero 2026 regular-season evidence.
Are fantasy managers more likely to gain an edge by exploiting Week 1 matchups, or get themselves into trouble by thinking they know more than they actually do?
Yes. And yes.
Battling Variance and Volatility
This is where I remind you that the NFL is designed to create unexpected outcomes. The week-to-week variance isn't a bug; it's a feature.
But that doesn't mean fantasy investors shouldn't lean into logical approaches based on the data available. Even if the best decisions don't always yield the desired results, making the best decisions still matters.
So assessing matchups and where teams stand in the moment is important.
Even in Week 1, when the stream of real-time data is a trickle at best. Yet here we are, diving into it.
So which matchups should we attack, and which ones have danger written all over them?
My Favorite Matchup
Los Angeles Chargers vs. Arizona Cardinals
This is the cleanest matchup to attack this week. Arizona allowed 28.7 points per game last season, 29th in the league, and surrendered 230.8 passing yards and 126.9 rushing yards per game.
The market agrees: Los Angeles is favored by double digits with an implied team total around 28 points.
So if the Chargers are one of our highest-confidence offenses this week, we want exposure to all the front-line pieces on our rosters -- Justin Herbert, Ladd McConkey, and Omarion Hampton top the list.
As USA Today's Jacob Camenker notes, Herbert was pressured a league-high 288 times in 2025, but still posted a strong fantasy season. He should be better protected in 2026 as tackles Rashawn Slater and Joe Alt return from injury.
The Cardinals had a 31.6 percent pressure rate last year -- which ranked 26th in the league, per the NFL's Next Gen Stats -- so they may have trouble rattling Herbert in this matchup.
Can We Dig Deeper?
Yes, we can.
Arizona ranked 24th in pass defense last season at 230.8 yards allowed per game. They surrendered receiving touchdowns to 25 different players and allowed six players to catch multiple TD passes in a game.
Quentin Johnston also showed last year that his fantasy profile is disproportionately driven by touchdowns and chunk plays -- which is exactly what we're hunting in a favorable matchup.
Though much of the fantasy football attention is rightfully on McConkey, Johnston could benefit most from coordinator Mike McDaniel's offense.
As ESPN.com's Ben Solak notes, Johnston is one of the league's preeminent vertical receivers, and his average speed last season (15.08 mph) was eighth among all receivers, second if we exclusively look at players over 200 pounds.
The McDaniel offense is among the league's best at creating YAC for speedy athletes, and Johnston will benefit from those targets over the middle.
But to really unlock a new level of this offense with the big-armed Herbert at the helm, Solak believes the Chargers need Johnston's runaway downfield routes to connect.
If Johnston delivers this year, the Chargers will put secondaries in an impossible bind.
This week? Johnston's Footballguys projection calls for a WR41 finish, but the matchup opens the door to WR3 or better production.
Is There a Downside?
The Chargers controlling this game could cap Herbert's ceiling, but not enough to make me dial back on him or the supporting cast.
Los Angeles may open up with a pass-heavy approach to get Herbert and new offensive coordinator Mike McDaniel on the same page.
At some point, however, the Chargers will look to salt the game away with a heavy dose of Hampton.
According to Bleacher Report's Kristopher Knox, Arizona ranked 24th in yards per carry allowed last season and surrendered 19 touchdowns on the ground. The Cardinals allowed 11 games of 15-plus fantasy points to running backs last season, and five of those came in the final six weeks alone.
The Cardinals didn't significantly improve their defense in the offseason either, meaning Hampton should face an attractive matchup.
He should also see a massive workload in this home game, which, as ESPN.com's Tristan Cockcroft pointed out, featured the week's widest opening spread (-10).
A Close Second
Baltimore Ravens at Indianapolis Colts
Indianapolis allowed 247.9 passing yards per game last season, tied near the bottom of the league, while Baltimore enters as a road favorite in a game with one of this week's healthier totals.
Lamar Jackson is a candidate to finish as the QB1 on any given Sunday. But this matchup could increase his odds.
In addition, Zay Flowers just got paid. This is the kind of matchup where Baltimore can get an immediate return on investment.
And what about Derrick Henry?
Indianapolis was much better against the run than the pass last year. Does that matter when we're talking about a player like Henry in this offense?
Probably not.
Henry is a "start your studs" player -- even in Week 1, when real-time data hasn't confirmed our historical expectation.
So Jackson, Flowers, and Henry are all locks to start. Who is the less-obvious Baltimore player you want attached to Jackson in this matchup?
It's Actually Obvious
Tight end Mark Andrews, whom you might have drafted as your TE2 this year, is underrated relative to his Week 1 expectation.
Andrews gets a matchup where Jackson should have opportunities in scoring territory, and the current market appears considerably less enthusiastic about Andrews than it has been historically. The Colts allowed the second-most yards and the seventh-most points to tight ends in 2025.
Ground and Pound
Dallas Cowboys at New York Giants
The Giants allowed 145.3 rushing yards per game last season -- 31st in the NFL -- and 25.8 points per game. Dallas enters as a slight road favorite with a healthy implied total.
Could this be a Javonte Williams game?
Yes.
As SI.com's Michael Fabiano notes, Williams has the entire Cowboys backfield to himself, as the team cut Jaydon Blue. In addition to the overall production allowed, the Giants surrendered the fourth-most points to backs last season, and that was before the team traded star nose tackle Dexter Lawrence II.
Also, Williams racked up 25 fantasy points in his last meeting against the NFC East rival.
But Wait, There's More
Should we dial back on the passing game then?
No.
Fabiano notes that Prescott has had plenty of success in his career against the Giants, averaging nearly 20 fantasy points in 15 meetings in which he has played at least 50 snaps. New York was one of the most vulnerable teams against quarterbacks at home last year, too, allowing 19.5 points per game.
CeeDee Lamb and George Pickens remain lineup locks, and Jake Ferguson is a serviceable option, even though the Giants held opposing tight ends to a respectable 11.2 points per game last year.
The Two-Way Street
Cincinnati Bengals vs. Tampa Bay Buccaneers
This game carries one of this week's highest projected totals -- in the low 50s.
For the Bengals contingent, Tampa Bay allowed 238.2 passing yards per game last season, 27th in the league, and 30 passing touchdowns.
That sounds like an invitation for Joe Burrow, Ja'Marr Chase, and Tee Higgins. You don't need my permission to start that trio -- or Chase Brown, for that matter.
But the Buccaneers will have a plan.
According to PewterReport.com's Scott Reynolds, stopping Brown early and setting up third-and-long situations can lead to Todd Bowles' defense teeing off against a subpar Bengals offensive line and getting to Burrow.
But Burrow, Chase, and Higgins could make this a track meet on the scoreboard if the offensive line can hold up and head coach and play-caller Zac Taylor can exploit a young and inexperienced Bucs secondary.
The Other Side of the Coin
Baker Mayfield just cashed in with a $165 million contract extension on Tuesday, and now he gets to take on a Bengals pass defense that's still plenty exploitable.
Fabiano notes that only two teams gave up more points per game to road quarterbacks last season, and nine different quarterbacks managed multiple scoring strikes against Cincinnati.
According to ESPN.com's Tristan Cockcroft, the Bengals finished 2025 with the sixth-most-favorable matchup for quarterbacks. While they added Jonathan Allen and Lawrence at defensive tackle and Boye Mafe on the edge during the offseason, they still have a long way to go to straighten out a unit that posted the league's worst pass rush win rate.
Would I prefer Mayfield with the chip that would have come without the contract extension? Sure. But the matchup is too good to pass up.
Bucky Irving might have it even better, though. By 2025 numbers, no defense allowed more fantasy points to running backs than the Bengals did.
The Bengals interior line should hold up better with Allen and Lawrence this season. Nonetheless, Irving and Kenny Gainwell both deserve a look -- Irving as a No. 2 fantasy back, Gainwell as a PPR flex starter in Week 1.
A Daunting Task
Buffalo Bills at Houston Texans
Houston allowed only 17.4 points per game last year, second only to the Seattle Seahawks. The Texans were also top six against both the pass and run.
And now Josh Allen walks into Houston.
Should We Consider Sitting Allen?
If you drafted Allen, you're starting him every single week. Expectations should be high.
But they should be lower this week.
According to SI.com's Jared Koch, the Texans are one of the few teams that Allen has routinely struggled against throughout his eight-year career -- and the four-time Pro Bowler hasn't struggled against many.
Houston is just one of two teams against whom Allen has a losing record, going 1-4 in their five matchups to this point.
Still, you didn't invest the draft capital necessary to secure Allen's services to sit him in a tough matchup in Week 1 -- or any week for that matter.
Meanwhile, I expect big things from DJ Moore this season. But again, I'm setting my sights lower this week, as Moore is likely to draw a heavy dose of star Texans cornerback Derek Stingley Jr.
Fabiano notes that last season, Houston allowed the third-fewest points and yards to wide receivers, and the position scored just 10 touchdowns (tied for the third-fewest).
I'm not advocating benching Moore, but setting realistic expectations is always helpful.
The same goes for Dalton Kincaid.
As Cockcroft pointed out, the Texans allowed more than 13 fantasy points to tight ends in only three games last season, and all three of them were by elite players: Trey McBride, Brock Bowers, and George Kittle.
Even if you believe Kincaid's talent isn't far off that group, his usage is.
He averaged 4.17 targets per game in 2025, a number exceeded by 23 other tight ends who played in at least half their teams' games.
Not So Fast
Washington Commanders at Philadelphia Eagles
Philadelphia finished top five in scoring defense last season, and there's a legitimate argument this defense could be even better in 2026.
That's a rough Week 1 draw for Jayden Daniels and company.
And Daniels is the focal point.
The third-year quarterback is healthy again after an injury-shortened 2025 season. He remains one of the league's most dangerous dual-threat weapons. His ability to extend plays can turn a perfectly defended snap into a 20-yard gain in an instant.
But SI.com's Phillip Hughes contends the Commanders' biggest concern heading into Week 1 is the offensive line, and it revolves around protecting Daniels from the Eagles' defensive front.
Philadelphia's strength is up the middle, with defensive tackles Jordan Davis and Jalen Carter; as fate would have it, the interior is also the place Washington has the most concern.
If Philadelphia controls the game and forces Washington into obvious passing situations, who steps up to help Daniels?
The Commanders' top two receivers are Terry McLaurin and Stefon Diggs, a couple of aging players who Philly Voice staffer Jimmy Kempski believes have something to prove.
McLaurin will turn 31 next Tuesday. He had his worst season in 2025, by far, after a contentious "hold-in." He missed seven games due to injury and had just 582 receiving yards after five straight seasons in which he topped 1,000 yards.
Diggs will turn 33 during the season.
While this is his fourth team in four seasons, Diggs has been productive. In 2025, he was the Patriots' leading receiver, with 85 catches for 1,013 yards and 4 TDs.
The Decision on Daniels
Am I benching Daniels, who was drafted as QB6 in Round 7?
While it's not as significant an investment as Allen owners made, it's still pricey for a QB. So the same argument I used with Allen -- you didn't pay up to sit him in tough matchups -- applies here.
But also, for quarterbacks outside the Allen, Jackson, Burrow tier, I'll remind you the quarterback position is deep this year.
Daniels' Footballguys projection calls for a QB12 finish this week; I rank him as my QB13.
Consider that permission to consider other options if you're so inclined.
