Start Marvin Harrison Jr. over J.K. Dobbins — Week 1 Start/Sit Verdict

Harrison's route volume edges Dobbins' shaky earned role

Dobbins is the clear early-down back in Denver now — Yahoo Sports confirms it — but a 4% target share means almost all his value is tied to volume he isn't getting enough of, even with a plus game script. Harrison Jr. is stuck in an ugly Arizona script as a big underdog, yet he's playing nearly three-quarters of the snaps at a true X-receiver spot, which keeps him live for targets even if the Cardinals fall behind. The margin here isn't really about talent or matchup toughness — both defenses grade almost identically — it's about who touches the ball enough to hit their number. Neither is a confident add, but Harrison's route share gives him more paths to a usable week than Dobbins' non-existent passing-game role.

What flips it: A Denver blowout with heavy red-zone work flips this to Dobbins; a competitive Arizona game that stays pass-heavy locks it in for Harrison.

Why J.K. Dobbins

Sit· medium

Veteran RB in a lead-back role. Decisive one-cut runner with explosive burst when healthy, key early-down workload.

RB37 with a 9.5-point projection, a 4% target share and a top-third-tough KC front — the volume and pass-game work aren't there to clear a 12-team flex.

Denver's clear lead back per Yahoo Sports, so a positive script could mean valuable red-zone carries late.
Favored by 2.5, which for a between-the-tackles runner means more clock-killing volume if Denver leads.

The call

Consensus has him at RB37 for 9.5 PPR points, which is replacement level or below in a 12-team league — you can do better on the flex.
Kansas City's defense grades 9th of 32 in the DvP composite (32 = softest), so this is a top-third-difficult matchup for a runner who lives on ground volume.
A 51% snap share and just a 4% target share over 10 games means he's splitting work with RJ Harvey and offers almost no PPR safety valve if the run game stalls.
A 20.0 implied team total with a 2.5-point spread points to a tight, low-scoring script — not the blowout lead that would unlock a heavy Dobbins carry count. A confirmed Harvey absence or a bigger snap spike would flip this to a start.

Why Marvin Harrison Jr.

Toss-Up

Boundary X receiver with elite pedigree but uneven 2025 (41/608/4 in 12 G). Projected WR1 still working to deliver on No. 4 overall draft profile.

Toss-up — WR31 consensus, projects WR32 this week: LAC is the 9th-toughest matchup vs WRs, 17.0 implied team total caps the ceiling.

71% snap share at a true X-receiver spot keeps him live for targets even when the offense struggles.
Big underdog script can mean more Arizona pass attempts and garbage-time looks despite the low implied total.
