Week 1 Start/Sit: Our Model's Top Calls (Powered by Opportunity-Weighted DvP)
Everyone knows to start their first-rounders. Our new opportunity-weighted DvP model tells you which Week 1 matchups actually amplify the usage, and puts a graded number on every call.
Ashton Jeanty: fantasy points, matchups, and our calls
Defense-versus-position is the oldest trick in the start/sit drawer, and it is usually used wrong. "Team X gives up the most points to running backs" tells you nothing if the back you are starting only sees ten touches. A soft matchup is only worth something when a player has the snaps and the opportunity share to actually punish it.
That is what our new opportunity-weighted DvP model does. It scales a defense-versus-position rating by how much real opportunity a player commands, measured against his positional peers. Opportunity share is snap rate times target share for pass-catchers, snap rate times carry share for backs, so a player who owns his team's snaps and touches gets the full weight of a soft matchup while a bench body gets almost none of it. A great matchup on a bench body scores low. A great matchup on a workhorse scores high. Our model only tags a spot "soft" when the opportunity-weighted number clears the positional bar by a wide margin, so a low-volume player in a good spot no longer earns the label.
Here are our highest-confidence Week 1 calls, straight off the start/sit board. Every one names the player, the matchup, and the exact edge metric behind it. These are predictions, not opinions: each carries a projected PPR total with a floor and a ceiling, and we grade them against the box score after Week 1. Our public track record across 15,216 graded calls sits at a 77.2% hit rate, and this is how we add to it.
The backs: three LOCKs, and a rookie with the biggest edge on the board
Ashton Jeanty (LV) vs Miami is the boldest call we have. His opportunity-weighted matchup score of 42.8 is the highest of any player at any position in Week 1, and it is not close. It is built on an 85.5% snap share and a 68.8% opportunity share, meaning the Las Vegas backfield runs through him, walking into a Miami front that our defense-versus-position rating grades as one of the softest for running backs. We project 16.7 PPR with a 13.2 floor. For a rookie in his first NFL game, that is a lot of green, and it is a LOCK.
Bijan Robinson (ATL) vs Pittsburgh is our top overall projection at the position, 20.6 PPR on an 80.8% snap share and a 52.6% opportunity share. The matchup score of 30.9 confirms it: heavy usage into a soft spot, floor of 17.1. This is the safest start on the entire board and a clean LOCK.
Christian McCaffrey (SF) vs the Rams rounds out the LOCK backs at 19.1 projected PPR. An 83.8% snap share and a 54.4% opportunity share against a favorable Rams matchup produce a 30.4 score and a 15.6 floor. Nothing cute here, and that is the point: the model will not talk you out of the obvious plays, it just shows you the math underneath them.
The receivers: usage plus matchup, not name recognition
Amon-Ra St. Brown (DET) vs New Orleans posts the highest receiver matchup score we have, 34.5, on a monster 92.5% snap share in a game our model reads as high-scoring. Projected 19.7 PPR, 16.1 floor, LOCK. The Saints matchup plus his target volume is the exact combination the opportunity weighting is built to reward.
Ja'Marr Chase (CIN) vs Tampa Bay grades at a 33.1 matchup score on a 90.2% snap share, 18.3 projected PPR with a 14.7 floor. Jaxon Smith-Njigba (SEA) vs New England is right behind at 33.1, a 90.0% snap share for a 16.8 projection and a 13.3 floor. Both are LOCKs, and both are cases where the model likes the matchup as much as the player.
One lean worth the flex spot: Chris Olave (NO) vs Detroit carries a 32.3 matchup score, one of the highest receiver edges on the board, on an 86.5% snap share. We project 16.8 PPR with a 13.3 floor. It is a LEAN rather than a LOCK because the projected finish sits just outside our top tier, but the matchup is loud, and Olave is the kind of name that slides in redraft.
Tight end and quarterback: the positional edges
Trey McBride (ARI) vs the Chargers is our top tight end call, a LOCK at 15.7 projected PPR. Tight end DvP numbers run smaller than skill-position numbers, so the story here is usage: a 94.8% snap share and a 30.2% opportunity share drive a 25.8 matchup score, with a 13.4 floor that is elite for the position.
Justin Herbert (LAC) vs Arizona headlines the quarterbacks, 19.0 projected PPR on a full workload in a game the model reads as high-scoring. His 23.2 matchup score clears the quarterback bar, and the 13.0-to-23.8 floor-to-ceiling range is the widest of any call here, which is honest: quarterback outcomes swing, but the matchup points up. LOCK.
And who we are not fading
A note on the sit side, because accountability cuts both ways. The model is not fading a single workhorse or target-earner on matchup alone this week. Every running back, receiver, and tight end we flag to sit on matchup is a low-volume, deep-bench name, not a starter you were agonizing over. That restraint is the feature: a start/sit tool that cries wolf on your studs every week is not a tool you can trust. When we do flag a stud to sit, it will mean something.
