A roster under a cap is not the most talent you can buy. It is the most surplus you can fit.
Building the fifty-three is a surplus problem, spending the cap by positional value and sequencing it across the multi-year ledger.
A tight fifty-three, and the cap is the binding constraint.
Roster construction forks by engine, because the two games build rosters differently. A composite pro roster: a tight fifty-three plus a sixteen-player practice squad under a hard cap, where every player carries a cap hit.
The cap is the binding constraint, positional value sets where a dollar buys the most winning, and surplus is the objective function. The four channels compose the fifty-three, each with its own surplus signature, and the roster read nets them into a single cap-constrained build. The best roster is the most surplus that fits under the cap.

Pay the premium positions. Find the low-leverage cheap.
A dollar spent on a premium position buys more winning than a dollar spent on a low-leverage one, because positional value, the same WAR-layer hierarchy the Team KR weight carries, says so. So a disciplined build pays the premium positions and finds the low-leverage production cheaply.
This is the cap-side expression of the same positional-value hierarchy the Team KR weight carries on the field, so the roster read and the team read agree by construction. A roster that spends evenly leaves winning on the table. Spend the cap by positional value, pay the premium and find the low-leverage cheap.

Time the rookie window and the cliffs, check what breaks.
Because the cap is a multi-year ledger, the build is sequenced across seasons against the multi-year cap projection, and then the finished roster is stress-tested, because a tight fifty-three has little cushion when the injuries of a long season land.
The fragility flags are informational and compound, a roster with several is structurally fragile regardless of its headline Team KR, and the protection-unit and quarterback-cliff flags tie the roster read to the weak-link handling in the team read. The tight fifty-three is why depth and fragility matter more in the pro build. The surplus is only realized if the roster survives the season.
Illustrative on the real multi-year and fragility layer (the rookie window, extension cliff, and dead-money tail sequenced against the cap projection, the peak-when-structure-and-window-align build, the Depth KR and the quarterback-cliff fragility). Composite roster, demonstration figures.
The best roster is the most winning per cap dollar that survives the season.
Build the surplus, spend it by positional value.
Pro Roster Intelligence builds the tight fifty-three as a surplus-maximization under the cap, allocates the cap by positional value, sequences the build across the multi-year cap projection, and stress-tests the roster for depth and the quarterback cliff.
