Jets D/ST or 49ers D/ST: Who Should You Start?

Preliminary board

2026 Week 4 · deterministic head-to-head · Verdicts based on PPR scoring.

Verdicts sharpen as practice reports land.

The 49ers edge this pair, though Denver keeps them in sit territory

The 49ers get the nod because Denver’s lower scoring outlook and the home setting give this unit a more favorable path than the Jets have against Chicago. The Jets can pressure a Chicago offense that allows more sacks, but the Bears’ high implied total puts a ceiling on the payoff. The separation is narrow, and Denver’s modest turnover rate keeps the 49ers from becoming a confident start; the board’s sit verdict still applies.

What flips it: A meaningful rise in Denver’s implied total that closes the gap with Chicago’s.

Why Jets D/ST

Toss-Up

Toss-up — a middling defensive matchup (No. 17 this week): CHI protects the ball (1.0 turnovers a game), and Vegas has them at 27 points.

  • Chicago’s sack allowance gives the Jets a clearer route to a useful pass-rush result.
  • The Jets’ better case is pressure, not a favorable scoring environment.

Why 49ers D/ST

Sit

Sit — a bottom-tier defensive matchup this week (No. 14): DEN protects the ball (1.3 turnovers a game), and 5.8 pts projected vs DEN.

  • Denver’s lower scoring outlook matters more than the small projection gap between these units.
  • The home setting supports the 49ers, even though Denver is not a high-sack opponent.
