Fantasy football is officially back. Honestly, there is nothing quite like the panic that sets in five minutes before the Thursday night kickoff when you realize you're starting a defense that might actually give you negative points. It happens every single year. You spent all summer scouting sleepers and debating whether to take a quarterback in the second round, and now you’re staring at week 1 dst rankings wondering if the Arizona Cardinals are actually a "safe" play.
Spoiler: safety is an illusion in Week 1.
But we can be smart about it. Winning your opening matchup isn't about finding the next 1985 Bears; it’s about finding the most incompetent offensive line or a rookie quarterback who still thinks he can outrun an NFL edge rusher. In 2025, the landscape has shifted. We've seen massive trades—Micah Parsons in a Packers jersey still feels like a fever dream—and coaching changes that have completely flipped the script for several units.
The No-Brainers: Week 1 DST Rankings Top Tier
If you were the person in your draft who reached for a defense in the 9th round, this is your time to shine. You paid a premium for the Denver Broncos, and you're getting exactly what you paid for right out of the gate. Denver finished last season as the top fantasy defense, averaging over 10 points a game. They were first in PFF’s Pass Rush Productivity and EPA per play.
Now, they get to welcome rookie Cam Ward to the league.

Playing a rookie QB in their first start is the ultimate cheat code for fantasy defenses. Ward might be the future of the league, but walking into Mile High against a Sean Payton-coached defense is a brutal way to start a career. Expect sacks. Expect at least one "welcome to the NFL" interception.
Then you have the Pittsburgh Steelers. They’re heading into a matchup against the Jets, and while the Jets have improved, the Steelers' front seven is still a nightmare. Mike Tomlin basically confirmed Alex Highsmith is good to go despite the groin issue. Facing Justin Fields—who we know can be a sack magnet—behind a Jets line that is still trying to find its chemistry is a recipe for a double-digit fantasy day.
Why the Arizona Cardinals Are the Week 1 Streamer of Choice
Kinda weird to see the Cardinals this high, right? Last year they were bottom-half in almost every category. But the draft changed things. Adding Walter Nolen and Will Johnson (who was a total steal, by the way) has transformed this secondary. Even with Nolen starting on the PUP list with that calf injury, this unit is rejuvenated.
The real reason they are a smash play in any week 1 dst rankings list is simple: Spencer Rattler.

The Saints are starting Rattler, and while he has talent, his 57% completion rate in college and preseason is a red flag you can see from space. New Orleans is missing Chase Young, which takes the pressure off Arizona’s offense and allows their defense to stay fresh. If you’re looking for a team you can grab for free off the waiver wire, this is the one.
The "Trap" Matchups to Avoid
Don't do it. I know the Dallas Cowboys usually put up huge numbers, but life after Micah Parsons is going to be a transition. They are playing the Philadelphia Eagles. The Eagles have one of the most potent offenses in the NFL and allowed the eighth-fewest points to fantasy defenses last year.
Philly’s line is too good. Saquon Barkley is still a monster. If you start the Cowboys, you’re basically praying for a garbage-time pick-six to save your week.
Similarly, I’d be very careful with the Kansas City Chiefs. They’re facing the Chargers in what looks like it’s going to be a high-scoring shootout. The over/under for this game is high, and while the Chiefs' defense is elite in real life, fantasy points come from turnovers and sacks. Justin Herbert doesn't give many of those away, even if Trent McDuffie is blanketing his best receiver.

Streaming Options for the Desperate
If the Broncos and Steelers are gone, and someone in your league already sniped the Cardinals, don't panic. There are still a few gems hiding in the weeds.
- Washington Commanders: They face the Giants and Russell Wilson. Wilson is still taking about 3 sacks per game. With Bobby Wagner and Frankie Luvu in the middle, Washington is going to be aggressive.
- New England Patriots: Mike Vrabel’s debut in Foxboro is against the Raiders. Geno Smith is a steady vet, but the Raiders' line is a mess. If Christian Gonzalez plays, this secondary could be a top-5 unit this week.
- Cincinnati Bengals: Betting against Joe Flacco is a time-honored tradition. He’s a turnover machine, and with Trey Hendrickson back after his new deal, the Bengals' pass rush is going to be in Flacco’s face all afternoon.
Actionable Strategy for Your Lineup
Stop looking for the "best" defense and start looking for the worst offensive environment. A great defense against a great offense is a coin flip. A mediocre defense against a disaster offense is a gold mine.
Check the Vegas totals. You want to target games with the lowest over/under.
Watch the injury reports. If a team is missing their starting left tackle, that's an automatic boost for the opposing DST.
Be ready to pivot. Don't be married to your drafted defense. If the Minnesota Vikings are sitting there on the wire and they're playing a backup QB, drop your "name brand" defense and make the move. Winning Week 1 is about being cold-blooded.
Check your waiver wire for the Arizona Cardinals or the Washington Commanders immediately. If you have the Denver Broncos, you're set—just sit back and watch the rookie mistakes pile up.
