San Francisco opened the preseason with a 30-9 loss to Denver in Santa Clara, a result that stings more for fantasy managers than for the final scoreline. Fourteen SF players logged snaps in a game that featured turnovers and inconsistent quarterback play, underscoring the depth concerns and the risk around volatile backup-QB performance early in the year.

Three SF passers combined for multiple interceptions while the 49ers’ offense failed to sustain drives after a bright opening by Patrick Taylor Jr. on the first drive. The Broncos dominated across the major offensive metrics, and Kyle Shanahan voiced clear frustration about the miscues: four turnovers and a clump of sacks and drops that could impact early-season depth charts.

In the fantasy lens, Purdy remains the clear QB1, but the night offered little signal from Mac Jones, Carter Bradley, or Tanner Mordecai—none of whom flashed a path to meaningful Week 1 action. Abdullah’s fumble and the trio of picks raise questions about the backups’ reliability. The second preseason tilt against the Raiders on the road becomes pivotal for evaluating SF’s back-end roster and the potential breakout candidates behind the starters.
