Josh Allen or Justin Herbert: Toss-Up — Week 1 Start/Sit Verdict

Allen's rushing floor meets Herbert's plush total — split the uprights either way

Josh Allen and Justin Herbert grade out as basically the same start this week, just built differently. Allen's goal-line and designed-run volume gives him a rushing cushion that holds up even against a tougher pass defense, while Herbert leans entirely on Los Angeles' huge implied total and a defense that offers little resistance through the air. The gap in raw points is noise, but the paths to those points aren't identical — one is floor-driven, the other ceiling-driven. Either can finish as the better real-life score without the model's lean being wrong.

What flips it: A blowout that shrinks Herbert's second-half dropbacks, or a tight game that pushes Allen into more designed runs, decides it.

Why Josh Allen

Start

Franchise QB and MVP-caliber dual threat. Elite arm strength with designed-run and goal-line rushing volume.

Start — every-week QB start at consensus QB3: HOU is the 8th-toughest matchup vs QBs, 98% snap share in 2025.

His designed-run and goal-line rushing volume gives him scoring paths a shootout or a tight game both support.

Why Justin Herbert

Start· high

Franchise starting QB with elite arm strength. Big-bodied pocket passer with underrated mobility, now in Mike McDaniel's new offense.

QB10 with a 19.0-point projection, a 28.5 implied total and a matchup ranked 22 of 32 — easy QB1 play in 12-team leagues.

A 28.5 implied total against a soft pass defense hands him the higher realistic ceiling of the pair.

The call

Consensus has him as QB10 at 19.0 projected points, which is starter territory in every 12-team format regardless of matchup.
A 28.5 implied team total means Los Angeles is expected to score plenty, and Herbert is the locked-in QB with no injury designation.
Arizona's defense grades 22 of 32 against the position (softer half of the league), though the sample is thin so it's a nudge rather than the main argument.
Only real drag is the -11.5 spread: a big lead could turn into a run-heavy fourth quarter and cap his passing volume, but the implied total says the points come first.
