CURRENT LAS VEGAS LINES
| Market | Current Line | Opening Line | Sharp Signal |
|---|---|---|---|
| Spread | Seahawks ‑7 | Seahawks ‑6.5 | Sharp steam on Seattle |
| Total | 45–45.5 | 46.5 | Sharps hitting the Under |
| Moneyline | SEA ‑340 / SF +270 | SEA ‑300 range | Seattle ML heavily steamed |
Interpretation: A move from SEA ‑6.5 → ‑7/‑7.5 is pure sharp action, not public. Books are protecting against Seattle blowout risk.
Last Meeting: Jan 3, 2026 — Seahawks 13, 49ers 3
Seattle enters as the No. 1 seed with the NFL’s top scoring defense (17.2 PPG allowed) and just held San Francisco to 173 total yards in their Week 18 matchup. The Seahawks are healthy, rested, and playing their first home playoff game since 2021 — a major situational edge.
San Francisco comes in as the No. 6 seed, but they’re severely depleted. Their win over Philadelphia cost them George Kittle (Achilles), and they’ll also be without Nick Bosa, Fred Warner, and Ji’Ayir Brown. QB Sam Darnold is questionable with an oblique injury, and several other starters are banged up.
The 49ers still have Christian McCaffrey, who scored twice last week, but Seattle’s defense has already shown it can contain him. The Seahawks’ “Dark Side” unit has been dominant all season and is built to take advantage of a wounded offense.
The teams split the regular‑season series, but Seattle controlled the more recent meeting — the one that mattered for playoff seeding.
Key Betting Angles:
- Seattle has the health edge, rest edge, and defensive edge.
- San Francisco is missing multiple All‑Pros and key starters.
SHARP BETTING CONSENSUS
1. Sharp Side: Seattle Seahawks
- Line moved toward Seattle despite public interest in the underdog.
- Books report sharp action on Seattle in divisional round markets.
- San Francisco is historically injured and thin at key positions.
2. Public Side: San Francisco 49ers
- Public loves big underdogs in playoffs.
- But the line moved against the public, confirming sharp Seattle money.
3. Total: Under 45.5
- Opened 46.5 → bet down to 45/45.5.
- Seattle has the No. 1 scoring defense (17.2 PPG allowed).
- 49ers missing major offensive weapons.
MATCHUP REORGANIZED WITH BETTING LENS
Seattle Seahawks (Sharp Side)
- No. 1 scoring defense in NFL (17.2 PPG allowed).
- “Dark Side” defense allowed just 173 yards to SF in Week 18.
- Home playoff game for first time since 2021.
- Fully healthy at key positions; Charles Cross returns.
San Francisco 49ers (Public Side)
Massive injury crisis:
- George Kittle – OUT (Achilles)
- Nick Bosa – OUT (knee)
- Fred Warner – OUT (ankle)
- Ji’Ayir Brown – OUT
- Sam Darnold – Questionable (oblique)
- Multiple defenders questionable
This is why they are the biggest playoff underdog in 40+ years.
Offense:
- McCaffrey bottled up in last meeting (48 yards rushing).
- No Kittle, no Bosa, no Warner = catastrophic matchup disadvantage.
SHARP CONSENSUS PREDICTION (Best Outcome)
➡️ Seahawks 24, 49ers 13
Recommended sharp-aligned positions:
- Seahawks ‑7 (or buy to ‑6.5 if available)
- Seahawks ML (parlay anchor)
- Under 45.5
- Seattle alt spread ‑9.5 (for plus money)
Seattle’s defense + SF’s injuries + line movement = sharp side is Seattle by margin.
