You spent months researching. You listened to every podcast, downloaded the spreadsheets, and maybe even paid for a premium "expert" draft kit. Then Sunday afternoon of Week 1 hits. By the third quarter, half your lineup looks like a disaster. It happens every single year. Honestly, week 1 fantasy projections are notoriously the most difficult numbers to get right because we are working with outdated data from the previous season and a handful of misleading preseason snaps.
Don’t panic yet.
The reality of fantasy football is that the first week is less about who scored the most points and more about who was on the field. Coaches lie. They lie in August, they lie in September, and they definitely lie about their depth charts. If you’re staring at a projection that says a rookie RB is going to get 15 touches just because he was a second-round pick, you’re gambling, not projecting. We have to look at the "sticky" stats—things like route participation and red zone targets—rather than just the final box score.
The Volatility of Week 1 Fantasy Projections
Why are we so bad at this? It’s simple. NFL teams change roughly 25-30% of their roster every year. New offensive coordinators bring entirely different philosophies. A team that ranked #1 in "neutral script" pass rate last year might have hired a defensive-minded coach who wants to "establish the run" in 2026. If your week 1 fantasy projections are based on 2025's tendencies, you're already behind.
Look at the offensive line play. This is the most underrated aspect of projection. If a star left tackle is out with a lingering calf strain, it doesn't matter how talented your QB is. He's going to be under pressure in 2.2 seconds. PFF (Pro Football Focus) often highlights that offensive line continuity is one of the biggest predictors of early-season success. Teams with five returning starters usually crush their projections in September while "superteams" with three new starters struggle to find a rhythm.
It’s messy.
Sometimes a player finishes as a Top 5 WR in Week 1 because of a 70-yard fluke touchdown on a busted coverage. That isn't "projections" working; that's variance. To actually win, you need to separate the signal from the noise. Is the volume there? If a receiver got 11 targets but only caught 3 for 40 yards, his projection for Week 2 should actually go up, even though his Week 1 score was "bad."
The "Rookie Wall" and September Expectations
We love the shiny new toys. Every fantasy manager wants to believe their rookie wideout is the next Justin Jefferson. But historically, rookie production in Week 1 is a massive trap. According to data from FantasyPoints, rookies rarely hit their peak utilization until after their team's Bye week.
Take a look at how Marvin Harrison Jr. or Malik Nabers were handled in their debuts. Coaches often use rookies as decoys or limit them to specific sub-packages early on. If your week 1 fantasy projections have a rookie as a must-start "Set it and Forget it" option, you should probably check the betting lines. Vegas is usually much more conservative with rookie props than fantasy sites are. Vegas wants to keep its money. Fantasy sites want your clicks.
Stop Trusting "Projected Points" on Your App
Your fantasy app—whether it’s ESPN, Yahoo, or Sleeper—is going to give you a specific number. "Player X is projected for 14.2 points." That number is basically a guess based on a median outcome. It doesn't account for the ceiling or the floor.
Football is a game of extremes.
A player doesn't usually score 14.2 points. They either score 6 points because they didn't get a touchdown, or they score 22 because they did. When looking at week 1 fantasy projections, you have to think in ranges.
- The High-Floor Play: These are your veteran possession receivers. Think Keenan Allen or Amon-Ra St. Brown. You know they're getting 8+ targets. Their floor is high.
- The High-Ceiling Play: These are the deep threats. Jameson Williams types. They might get 2 targets. If one is a TD, they've "beaten" their projection. If not, they've ruined your week.
If you are a heavy underdog in your matchup, you shouldn't care about the "projected" 14 points. You should be chasing the guy who could potentially give you 30. Conversely, if you're the favorite, you just need the guys who won't give you a zero.
Weather, Travel, and the "Hidden" Factors
It’s 95 degrees in Miami in September. That matters. We see players cramping, high defensive rotation, and a slower pace of play in the fourth quarter. Or maybe it's a West Coast team flying to the East Coast for a 1 PM kickoff. Data suggests these teams underperform their scoring projections by about 5-10%.

You also have to consider the "Revenge Game" narrative. While it sounds like a locker room trope, Mike Lombardi and other former NFL executives have often noted that coaches do occasionally script plays to favor a player facing his old team early in the season to build chemistry and "buy-in." It’s not a primary stat, but it’s a tie-breaker.
Defense vs. Position: The Great Week 1 Lie
"Start him, he's playing the worst defense against the run from last year!"
Stop right there.
Using last year's defensive rankings for week 1 fantasy projections is one of the fastest ways to lose. Defenses are extremely volatile year-over-year. A team that was "easy" to run on might have drafted two massive defensive tackles and hired a new coordinator from the Ravens' system. Suddenly, they're a brick wall.
Wait until at least Week 3 before you start trusting "Defense vs. Position" (DvP) stats. For Week 1, trust the individual talent and the expected game script. If a team is a 7-point underdog, expect them to be throwing the ball in the second half. That benefits the QB and the pass-catchers, regardless of how good the opposing secondary was six months ago.
Injuries You Aren't Paying Attention To
Everyone knows about the "Out" or "Doubtful" tags. The real edge is in the "Limited" participants. If a star WR has been limited all week with a hamstring issue, his week 1 fantasy projections might still show 15 points, but his snap count might be 50% lower than usual.
Soft tissue injuries are notorious for "decoy" games. The player stays on the field to draw coverage away from others but never actually gets targeted because he can't make sharp cuts. You’re better off starting a healthy WR3 on a high-powered offense than a "hobbled" WR1 in a bad matchup.
Actionable Steps for Week 1 Success
Don't let the "projection" numbers paralyze you. Use them as a baseline, but apply these filters before Tuesday's waivers or Sunday's kickoff:
- Check the Vegas Totals: Look for the Over/Under on the game. If the total is 51, there are going to be points. If it's 38, it’s going to be a slog. Favor players in the 51-point game even if their individual projection is lower.
- Target the "Slot" against New Coordinators: Rookie or new defensive coordinators often struggle with zone handoffs in the middle of the field. High-volume slot receivers are a "cheat code" for Week 1.
- Ignore Preseason Box Scores: Preseason is for conditioning and evaluating bubble players. If a starter had a 50-yard run in preseason, it was likely against guys who are now working at a car dealership.
- Watch the "Inactives" List Like a Hawk: 90 minutes before kickoff, the inactives are released. If a starting offensive guard is a surprise scratch, downgrade the RB immediately. The "hole" won't be there.
- Focus on Market Share: Use sites like PlayerProfiler to look at a player's share of the team's total air yards. If a player owns 40% of his team's air yards, the points will eventually come, regardless of a "low" projection.
Fantasy football is a game of probability. Week 1 is the highest-variance moment of the season. By focusing on volume, health, and coaching tendencies rather than the arbitrary number assigned by an algorithm, you put yourself in a position to survive the chaos. Trust the process, not the "14.2" on your screen.
