In this episode:
Run fit structures are defined by the “politics and religion” of defensive football, acting as the foundational geometry that dictates roster construction and secondary coverage.
Box spacing is categorized as “even” when there is an open B-gap bubble and “odd” when both B-gaps are closed by a defender.
Modern spread offenses frequently “drain the box” by using perimeter threats like bubble screens or flat routes to pull defenders away, forcing a standard seven-man box to function as a six-man fit.
Hybridized front techniques, such as the “lag nose” and “4i,” allow defenses to cancel gaps and squeeze vertical double teams while remaining in nickel personnel.
Elite NFL defenses, including the Seahawks and Patriots, increasingly utilize “passive pressures” and “read stunts” to reset the line of scrimmage and eliminate gaps without overextending via traditional blitzes.

Free agency signals draft intent; this episode explains how teams like the Steelers and Jets use veteran additions to stabilize specific schematic issues. Cody and Felix break down the defensive logic of the "Sweat Tax" and wide-nine pivots to explain how organizations structure their rosters for playoff contention heading into 2026.

In this episode:
Free agency serves as a signal for draft strategy, where current roster moves whittle down which positions a team will target in the early rounds.
The “Sweat Tax” defines the Jets’ and “new” defensive identity, as New York prioritizes massive interior linemen like T’Vondre Sweat to neutralize the A-gap run game. Compared to the Titans' pivot to the Wide-9 under Robert Saleh.
Schematic shifts toward the Wide-Nine and hybrid roles are emerging, with teams like Green Bay and Washington collecting versatile “misfit toy” defenders to raise their defensive floors.
A “Pokemon” approach to the draft is recommended for high-value positions, advising teams to collect as many receivers, edge rushers, and cornerbacks as possible, regardless of existing depth.
Veteran “adults” are being used to stabilize young units, exemplified by the Steelers’ offensive pivot under Mike McCarthy and the Patriots’ addition of Kevin Byard to their secondary

Cody Alexander and Felix Johnson break down the explosive first wave of NFL free agency, including the Rams' secondary overhaul and the high-stakes veteran trades reshaping the league. The episode analyzes the technical "why" behind signings like Maxx Crosby to the Ravens and the shifting quarterback landscape.
—
In this episode:
The Kansas City Chiefs are navigating a defensive hard reset, having lost cornerbacks Trent McDuffie and Jaylon Watson to the Rams while shifting toward an under-center run game with the signing of Kenneth Walker.
Veteran trades and signings are being used to raise defensive floors, specifically through Maxx Crosby’s move to the Ravens and Rashan Gary's joining the Cowboys, to stabilize their interior run defense.
A volatile quarterback market has left several teams in “quarterback purgatory”, marked by Malik Willis signing with the Dolphins for three years and the record dead cap hit following Tua Tagovailoa’s release.
Schematic defensive fixes are a priority for struggling units, as evidenced by the Buccaneers signing Alex Anzalone to address intermediate coverage issues and the Panthers adding Jaelan Phillips to provide a pass rush in Ejiro Evero’s system.
Teams are positioning themselves for the draft by securing veteran protection, such as the Raiders signing center Tyler Linderbaum to a massive three-year deal to support their future quarterback.

Cody and Felix analyze how NFL teams use GPS data and 18-minute interviews to evaluate 2026 Combine prospects like Caleb Downs and Reuben Bain. This episode explores the rise of the “first-round” Nickel and how hybrid Safeties are redefining defensive structures ahead of the 2026 free agency period.
—
In this episode:
The “Car Wash” Interview & Bias: Coaching staffs use 18-minute “car wash” interviews to gauge prospect personality, though some teams avoid these meetings to prevent personal bias from clouding film-based evaluations.
GPS Data vs. Track Speed: NFL teams increasingly prioritize Catapult GPS tracking metrics from college games over 40-yard dash times to determine a prospect’s true “playing speed”.
The First-Round Nickel: The nickel defender has evolved into a premium first-round position, serving as a vital “eraser” for modern defenses against heavy 12- and 13-personnel packages.
Physical Thresholds & Evaluation: Prospect assessments, such as Reuben Bain’s sub-31-inch arm length, highlight how failing to meet NFL physical prototypes can force schematic adjustments or cause draft-day slides.
Hybrid Safety Diversity: The 2026 class features a diverse group of hybrid safeties, such as Dillon Thieneman and Caleb Downs, who offer versatility in both deep-post and near-the-box roles.
