Why Christian McCaffrey

Start

RB1 and true feature back. Elite dual-threat volume with high-end receiving usage out of the backfield.

Start — every-week RB start at consensus RB5: LAR is the 2nd-toughest matchup vs RBs, 24% target share.

  • LAR ranks 2 of 32 against RBs (one of the tougher matchups, 0-game sample).
  • Vegas implies 22.8 team points as 3.0-point underdogs.
  • Listed RB on the latest depth chart with a 55% snap share.

Latest on McCaffrey

Status

Why J.K. Dobbins

Toss-Up· medium

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

Lead-back role vs KC but only 51% snaps and a 4% target share — 9.5 projected points and RB37 make him a TD-dependent flex dart.

  • 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

  • He's the clear top option in Denver's backfield ahead of RJ Harvey and Jonah Coleman, and he's carrying no injury designation after the camp soft-tissue issue — the role is real.
  • The usage caps the ceiling: a 51% snap share and 4% target share mean almost no PPR floor, so his value hinges on goal-line work in a game with just a 20.0 implied team total.
  • A 2.5-point spread keeps the script neutral enough to avoid a full pass-script wipeout, but RB37 and 9.5 projected points is flex filler, not a confident 12-team start.
  • Tip it to start if your alternative is a committee back with no goal-line role; tip it to sit if Harvey is carving out passing-down snaps.

Latest on Dobbins

Role

After managing a soft-tissue issue in camp, Dobbins is back to full health and is slated to begin the season as the Broncos' starter and lead runner.

CBS Sports, ESPN · Sep 3, 2026
Role

Dobbins is described as the clear top option in Denver's backfield entering September, giving Sean Payton a trusted lead runner ahead of RJ Harvey and Jonah Coleman.

Yahoo Sports · Aug 30, 2026

“I think it’s going to be a great night for us," Dobbins said. "… It’ll be a great way to start a season."
