Key Points:

• The Cincinnati Bengals' defense showed significant improvement in Week 1, particularly with a revamped defensive line and better rush defense, suggesting they could be a middle-of-the-pack unit or better this season.
• The Baltimore Ravens offense impressed with a strong performance from quarterback Lamar Jackson and innovative offensive line coaching, though injuries to key receivers like Zay Flowers could test their creativity moving forward.
• The Buffalo Bills' offense dominated with aggressive play-calling, including a high percentage of play-action passes and effective protection schemes, highlighting Josh Allen's best game in recent matchups against the Texans.
• The San Francisco 49ers defense displayed a more modern and versatile approach under coordinator Raheem Morris, using more two-high safety looks and dime packages, which helped contain a strong Rams offense despite some vulnerabilities against the run.
• The Chicago Bears' offense exploded for 59 points in Week 1, led by an improved Caleb Williams, while the Los Angeles Chargers struggled with run blocking and protection issues, indicating areas needing quick improvement despite high offensive potential.
