The Bills, Browns, Packers, and Cardinals all picked up wins in Week 6, and ESPN's NFL Nation reporters broke down what each victory revealed about these teams going forward.
Buffalo's offense continues to operate at an elite level. Josh Allen and the passing game are clicking, and the defense tightened up when it mattered most. The Bills are legitimate contenders in the AFC right now.
Cleveland's defense carried the load. The Browns leaned heavily on their pass rush and secondary, forcing turnovers and creating chaos. Deshaun Watson didn't need to be spectacular, just efficient enough. That formula works if they can maintain it.
Green Bay's win showed the Packers can compete with anyone on any given Sunday. Their offensive line dominated the line of scrimmage, giving Aaron Rodgers time to work. The defense also showed up in crucial moments.
Arizona's surprising victory puts the Cardinals back in the conversation. Their defense proved stingy, and the running game found rhythm. If Kyler Murray stays healthy and the offensive line holds up, this team has playoff potential.
The common thread across all four wins: strong defensive performances and teams executing their gameplan without freelancing. None of these victories came from desperation or magic. They came from doing the fundamentals right.
