2026 San Francisco 49ers Preview: Roster, Odds & Win Total

The gist

1. The roster is aging at key spots, with Trent Williams at 36, Fred Warner at 30, and Christian McCaffrey at 30, which limits the team's ceiling.
2. Defensive health is the deciding factor: a healthy Nick Bosa and Fred Warner makes them tough, but last year's pass rush ranked 32nd without them.
3. The hosts say to avoid futures bets at current odds and instead look for weekly matchup spots, selling the Niners when the market overrates early wins.
4. A December run of games against the Rams, Chargers, Chiefs, and Eagles will largely decide whether they finish fifth or sixth seed.
