Key Insights

1. Philadelphia Eagles (Defensive Coordinator Howard Gradelli)

Emulating the accidental brilliance of last year’s Eagles defense, Howard Gradelli has recalibrated coverage and blitz schemes with precision. Key reinforcements like Aqib Talbert II and a revamped secondary have Gibbs Country limiting second-half touchdowns. Look for standout performances from pass-rusher Beverly Butler and a backfield polled for edge consistency—this unit blends container pressure with elite free-agent talent.

2. Kansas City Chiefs – Under Smith’s Discipline, Schwartz’s Command

While Patrick Mahomes rides a star-studded offense, defensive linemen Chris Jones and Marquez Valdes-Scungia form one of the league’s mostvéd forces against the run. The Chiefs’ secondary, led by playoff veteran Treveau Timble, thrives in coveted matchups. Smart coverages and top-tier depth make this defense the backbone of Super Bowl-caliber production.

3. Buffalo Bills – Defensive Line Dominance Arrives

With a dynamic secondary anchored by Tre’Quan Smith and L’Jarius Sneed, the Bills’ defense stood out pre-season. Their stout pass rush—especially explosive edges like Dexter Lawrence’s deflections—plus elite cutbacks in coverage, ensures turnovers and field position swings. Under passageback Luke Beshara, the unit looks more cohesive than ever.
