Playbook
Playbook defense
FlagOS defense does not reuse offensive formations, route trees, or motion calls. A team begins with seven-body shells and separate responsibility objects. Teams own the words. FlagOS owns the structure.
Alignments
A shell is pre-snap geometry. Two High is not Cover 2. One High is not Man Free.
- Two High — five underneath, two deep
- One High — six underneath, one deep
- Three High — four underneath, three deep
- Man Shell — seven starting spots. Not an assignment-matching engine
- Custom — blank field
Man Shell does not auto-match defenders to receivers. Match links are play-owned.
Coverages
Post-snap responsibility. Starters: Man, Man Free, Cover 2, Cover 3, Custom.
Rushes
Immediate quarterback pressure. Starters: No rush, Left rush, Right rush, Middle rush, Custom. No rush is a real object. Spy is not a rush.
Adjustments
Conditional rules: Lock motion, Bump motion, Bunch box, Trips check, QB Spy, Custom.
QB Spy: Mirror the quarterback/run threat. Do not attack immediately.
Calls
A defensive call is alignment + coverage + rush + optional adjustments. The coach display name can be Black Green. The expanded line stays One High · Man Free · Middle rush.
