The KR says who he is. Development says who he becomes.
The forward engine projects his OVERALL as a banded survival curve by position and archetype, never touching the current number.
A projection is a survival band, priced by its uncertainty.
A composite edge rusher, age 23, in the rising phase of his curve. The current OVERALL is a fact from Player Intelligence. Everything to the right of it is a bet, and the honest form of the bet is a band: a median, a 75th-percentile high, and a 25th-percentile low, widening every year out.
There are no safe and risky players, only degrees of risk. A back can be done at 26 or productive at 30, and both are points on the same distribution. The engine never outputs a hard decline age, only a probability of sustaining production by year. A projection that hides its band is a guess wearing a number.

The position sets the curve. The archetype bends it.
Seven composite curves on one age axis. The point is the spread: the position sets the envelope and the differences are extreme, from the running back who peaks at 24 to the pocket quarterback who is still climbing at 29.
Every curve is a median with a wide band, corrected for survivorship (the players past 30 are the survivors, so a naive curve overstates old-player quality) and read through the archetype (explosive archetypes peak earlier and fall harder, skill-and-reading later and gentler). The engine decays each trait on its own schedule. One aging curve for football is a lie the position differences expose.
Illustrative Position Peak-Timing Model on the real structure (the position curves, the pocket-versus-dual-threat split, the trait-decay order, survivorship and archetype conditioning, the attrition tiers). Composite curves, demonstration figures.
A jump can be the player or his line. The engine says which.
A composite quarterback posts a +6.0 year-over-year jump. The question is not whether he improved. It is how much of the jump was him and how much was the situation around him, and the engine refuses to sell one as the other.
Believable over impressive, applied to growth. The engine projects each trait by its tier times age, snaps, environment, headroom, and Frame Upside, bounded so it cannot manufacture a leap. A back whose yards jumped behind a rebuilt line, and a receiver whose targets jumped when the other receiver got hurt, are opportunity. Credit the player for the player and the situation for the situation.
Illustrative development-versus-opportunity split on the real structure (the decomposition, the opportunity-loaded flag) and the developability tiers plus Frame Upside. Composite player, demonstration figures.
A projection is a survival band, not a promise, and the engine lays out the distribution and stops.
Project who he becomes. Price the bet.
Development forecasts the future KR as a banded bet across time, read through the position and the archetype, honest about which gains are the player's and about the attrition the sport runs on.
