The San Francisco 49ers were held to just 3 points in a 13-3 loss to the Seattle Seahawks in Week 18 — their worst offensive performance in years. The loss knocks the 49ers out of the No. 1 seed and drops them to the 6-seed, setting up a Wild Card playoff matchup with the Philadelphia Eagles.

We break down what went wrong offensively — the run game erased, offensive line breakdowns, Shanahan’s play-calling, Brock Purdy under constant pressure, and the missing impact of Ricky Pearsall. We also discuss the defense — 18 missed tackles, 180 rushing yards allowed, but still only 13 points given up.

Is this loss a warning sign — or a wake-up call before the postseason?
