Patrick Mahomes reminded everyone of his playoff bona fides, and C.J. Stroud served notice he's going to be a factor for years to come. A trip to Buffalo awaits Mahomes and the defending champion Kansas City Chiefs, while Stroud and the Houston Texans face the ultimate test in the top-seeded Baltimore Ravens.
On the NFC side, both North teams advanced. The Green Bay Packers stunned the second-seeded Dallas Cowboys, while the Detroit Lions held off the Los Angeles Rams. The Tampa Bay Buccaneers steamrolled last season's Super Bowl runner-up Philadelphia Eagles.
