Medical Protocol & Roster Construction Insights

Soft-Tissue Kinetics for Deceleration Route Runners

Receivers with physical, route-heavy profiles like Puka Nacua rely heavily on the adductor longus and gracilis muscles for hard plant deceleration on comeback and in-breaking dig routes. Returning prematurely before tissue remodeling raises subsequent re-injury rates past 30%, which is why coaching staffs declare it "not long-term" yet maintain aggressive practice holdouts.

Target Share Elasticity & Concentrated Offenses

In Sean McVay’s 11-personnel scheme, vacated targets rarely disperse equally. High-efficiency schemed reads gravitate toward the slot flanker (Cooper Kupp) and tight end release routes, while perimeter deep boundary receivers absorb variance without seeing direct volume 1-for-1.

How does the Re-Injury Hazard Curve work?

The mathematical curve utilizes an exponential decay hazard function parameterized by clinical injury grade, age coefficient, and game-management pacing. Playing in Week 1 post-strain exhibits peak vulnerability because collagen fiber organization requires 14–21 days to resist tensile shear during maximal sprint braking.

Can this model be applied to other NFL teams and receivers?

Yes. Select the "Custom Roster" preset or adjust the baseline target share, weekly team pass volume, and coaching stance sliders. The target redistribution algorithm reallocates volume based on positional beta-weights derived from empirical NFL offensive scheme distributions.
