Coaching
Scheme without the jargon dump. What teams are trying to solve, which tools they have available, and what to watch once the ball is snapped.
Pick the football problem
These concepts stay useful after one matchup is over.
Personnel
11, 12 and 21 personnel — and why substitution choices force defensive reactions.
RUN GAMEZone vs gap
The easiest way to understand whether blockers are responsible for space or creating a defined point of attack.
DEFENCECoverage
Cover 6, split-field structure and how quarterbacks identify the stress points.
SITUATIONDown & distance
Why play-calling changes dramatically between 2nd-and-2 and 3rd-and-12.
Melbourne's pregame protection question
Before 49ers–Rams, AGN used motion, chips and launch-point changes to explain the choices an offence has against an elite edge rusher. The game is over, so the piece is now a teaching example rather than a current preview.
Four questions that travel to any matchup
What problem is the defence creating before the snap?
Which player or alignment is forcing the offence to spend extra resources?
Can motion or formation reveal coverage or pressure structure?
What does the offence sacrifice when it adds protection help?
