Four underdogs enter the divisional round with real upset potential. The Bills, 49ers, Texans, and Bears each have a specific game plan to challenge favored opponents. Analyst Matt Bowen breaks down offensive and defensive keys for each matchup, focusing on personnel advantages and scheme adjustments.

Buffalo faces Denver's man-heavy defense, requiring quick passes to Khalil Shakir. San Francisco must create passing lanes against Seattle's Cover 2 without George Kittle. Houston's Kirk Collins faces a tough Rams defense, while Chicago's offensive juggernaut meets a disciplined Rams unit.

Success hinges on execution: Bills' safety Cole Bishop must contain vertical routes, while the 49ers need Brock Purdy to exploit intermediate windows. These blueprints rely on coaching adjustments and players winning individual battles, turning playoff pressure into opportunity for the wild-card survivors.
