Toss-Up

Why J.K. Dobbins

Sit· medium

RB1 and lead back. Decisive one-cut runner with burst; durability the long-standing question.

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.

Carries a Questionable tag — usually plays, but monitor the final report.
KC ranks 9 of 32 against RBs (one of the tougher matchups, 0-game sample).
Vegas implies 20.0 team points as 2.5-point underdogs.
Listed RB on the latest depth chart with a 51% snap share in 2025.

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 Jordan Mason

Toss-Up

RB2 in near-even split. Physical downhill runner with contact balance and short-yardage value.

Toss-up — RB40 by consensus and projection: 4% target share in 2025, 8.7 PPR projected vs GB.

GB ranks 17 of 32 against RBs (a middle-of-the-road matchup, 0-game sample).
Vegas implies 21.5 team points as 1.5-point underdogs.
Listed RB on the latest depth chart with a 43% snap share in 2025.
