The Niners are matchup-proof. Their front seven applies constant pressure, and their secondary can capitalize on bad throws. If you roster them, you’re set.
✅ Buffalo Bills – Take Advantage of a Rookie QB
A young quarterback facing Buffalo’s disguised coverages? Yes, please. Expect turnovers.
✅ Dallas Cowboys – Sack Machine
Micah Parsons alone is worth a few fantasy points. Dallas thrives against weaker offensive lines.
