Why Chargers D/ST

Start· high

DST3 projection at home as an 11.5-point favorite against an offense allowing 3.7 sacks per game with a 17.0 implied total.

ARI's offense gives up 3.7 sacks and 1.2 turnovers a game (2025), well above league average.
Vegas has ARI at 17 points as 11.5-point dogs.
Under-started: only 48% of leagues have them in, 12th among defenses, against a No. 3 matchup.

The call

The Vegas setup is everything for a defense: -11.5 at home with Arizona's implied total at 17.0 means a positive game script and a likely pass-heavy, mistake-prone opponent in the second half.
Arizona's line surrenders 3.7 sacks per game and the offense coughs up 1.2 turnovers per game — that's the pressure-plus-takeaway combination that produces DST spike weeks.
The model projects 7.5 points on 2.7 sacks, 0.7 interceptions and just 16.6 points allowed, which grades out DST3 this week — a clear start over any streamer.
Only 48% of leagues have this defense in lineups (crowd rank 12), so it's available in plenty of leagues despite the top-three projection.

Why Seahawks D/ST

Start

Start — the No. 5 defensive matchup this week: 7.1 pts projected vs NE.

NE's offense gives up 3.0 sacks and 0.9 turnovers a game (2025), near league average.
Vegas has NE at 20.5 points as 3.5-point dogs.
Over-started: 91% of leagues have them in, 1st among defenses, against a No. 5 matchup.
