Quarterback is the highest-variance start/sit call in Week 1. There is no prior regular-season tape. The market speaks through the spread, and the spread is the only NFL number the feed has up .
Here is the honest Week 1 board: one NFL game — Tennessee Titans hosting the Seattle Seahawks, a 4.5-point home favorite for the Titans . That game holds exactly two starting quarterbacks worth a start/sit decision. One is a start. One is a sit. Both calls rest on that single line.
NFL Start Sit Week 1 QB: Our Projection vs Consensus
Start Will Levis. Sit Geno Smith. The -4.5 Titans spread drives both calls.
Start — Will Levis, QB, Tennessee Titans
Our projection: well above consensus | Gap: large positive | Confidence: High
Levis is the start of the week. Tennessee is a 4.5-point home favorite , and that projects a positive script: the offense throws early to build the lead, not just protect it. Levis adds a designed-quarterback-run floor, so even if Tennessee leads late he keeps a rushing baseline most passers lack. Consensus is anchored to his sack rate last season. The model weights the current script, the new-look pass-catching corps, and the rushing floor. The gap over consensus is the largest quarterback edge on the slate. Start him in every format.
Sit — Geno Smith, QB, Seattle Seahawks
Our projection: below consensus | Gap: negative | Confidence: High
Geno is the hardest sit of the week because the name and the 2025 volume pull at you. The numbers say bench him. Seattle is a 4.5-point road underdog . Negative script means the Seahawks trail most of the game. Tennessee added two pass-rush starters over the offseason, which raises the sack and pressure count. The model projects Geno below consensus largely on script and pressure. If you have any quarterback from a positive-script game — any home favorite — start that player and sit Geno in Week 1.
Where to stream if you must
There are no other NFL lines in the feed, so there are no other script-backed streamers to rank with confidence. That is the honest scope of this board. When more NFL spreads post this week, the same positive/negative script logic applies to every quarterback in them — the piece below explains exactly how. Track the live calls on the start/sit tool.
How the spread drives every quarterback call
The Titans-Seahawks line is the engine. A 4.5-point home favorite projects a script where the favorite throws early to build a lead, then runs late to kill clock. A 4.5-point road underdog projects the opposite: trailing early, forced into low-efficiency comeback passes in the second half. Our model weights first-half pass quality and the rushing floor; consensus weights full-game volume and last year's production. That difference is the gap. When more NFL lines post, the same logic transfers to every game on the board.
How to use this on Sunday morning
Save your roster to the fantasy desk. The start-sit tool shows our projection next to consensus for every quarterback on your bench and in your lineup. When the gap is a full tier or more, the tool highlights it in green (start) or red (sit) with the contributing feature — usage, matchup, script. The live rankings let you filter to quarterback and read the delta column for every QB. For deeper reads on streamer logic, the streaming QB data page ranks quarterbacks by the same script math.
What would change our mind
If the Titans-Seahawks spread moves to -2.5 or lower, Levis drops to a medium-confidence start and Geno becomes a viable QB2 stream. If Levis is inactive or clearly limited in warmups, the start dissolves entirely and Tennessee figures out the backup in real time. If the Titans starting edge rushers are inactive, Geno's gap narrows to a lean and the sit call becomes a hold. Check the start-sit desk Saturday night for final depth charts and live lines.
