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

2026 Week 3 · deterministic head-to-head · Verdicts based on PPR scoring.

Start the 49ers — the lineup-share and opponent scoring edges are too wide to ignore.

49ers D/ST is started in more leagues (started rank 7 to 26) and faces the lower-scoring offense (17.5 implied points to 23.8). No signal favors the Titans this week. The gap is wide.

Why 49ers D/ST

Start· high

DST2 projection (7.5 pts) at home vs an ARI offense allowing 3.7 sacks/game, with a 17.5 implied total and SF favored by 11.5.

  • ARI's offense gives up 3.7 sacks and 1.2 turnovers a game (2025), well above league average.
  • Vegas has ARI at 17.5 points as 11.5-point dogs.
  • Under-started: only 65% of leagues have them in, 7th among defenses, against a No. 2 matchup.

The call

  • Projection ranks DST2 among 32 defenses at 7.5 points, a clear top-tier DST play this week.
  • The matchup feeds the pass rush and takeaways. ARI's offense gives up 3.7 sacks and 1.2 turnovers per game, which supports the projected 2.7 sacks and 0.5 INTs.
  • Game script is favorable. SF is an 11.5-point home favorite and ARI's implied total is just 17.5, so Arizona should be chasing and throwing into pressure while points allowed stay low (16.8 projected).
  • Lineup share of 65% (crowd rank 7) trails the projection rank, but that gap is no reason to hesitate. This is a lock-in start at DST.

Why Titans D/ST

Toss-Up· low

DST13 at 6.0 projected is right at the streaming line; NYG's 23.8 implied total caps the upside despite 2.8 sacks allowed per game.

  • NYG's offense gives up 2.8 sacks and 1.0 turnovers a game (2025), near league average.
  • Vegas has NYG at 23.8 points as 3-point favorites.
  • Under-started: only 2% of leagues have them in, 26th among defenses, against a No. 13 matchup.

The call

  • Projection sits at 6.0 points, DST13 among 32 defenses. That is just outside the top 12 in a 12-team league, which makes this replacement-level territory rather than a clear upgrade.
  • The sack angle is real. NYG allows 2.8 sacks per game, and Tennessee projects for 2.2 sacks plus 1.0 interception.
  • The ceiling is limited. NYG's 23.8 implied total and 23.4 projected points allowed point to a moderate scoring game, and 1.0 turnovers per game is not a giveaway-prone offense. Tennessee is also on the road.
  • What tips it: start the Titans if your alternative projects below 6.0 or faces a higher implied total. Sit them if a top-10 defense is available on waivers.
