The Deterrence Trap: Reclassifying Rim Protection by Career Success in the Modern NBA

A decade of interior-defense analytics — from the Dwight Effect onward — established that a rim protector's real value lies in suppressing close attempts, not in blocking them, and the modern tracking ecosystem now measures that block-independent deterrence directly. What the literature never asked is longitudinal: which deterrence archetype actually predicts a successful career? We classify 46 modern NBA centers (419 center-seasons) on two axes — a box-score axis (BLK/36 × AST/36) and a tracking-deterrence axis (rim-suppression × AST/36) — and map the resulting quadrants onto career production (PRA/36).

Quadrant membership discriminates career production at Kruskal–Wallis p = 0.003, surviving multiple-comparison correction; the same test on the block axis is weaker (p = 0.008). Sorting centers by measured deterrence rather than by blocks therefore separates careers more sharply than the box score does, and reclassifying from one axis to the other moves 30% of the pool (14 of 46) across quadrant lines. A secondary, directional result flags a failure archetype: the low-playmaking “swiper” posts the worst mean career-success composite (−0.195) and the “floor general” the best (+0.411), though that omnibus contrast does not clear family-wise correction (p = 0.16) and is reported as directional. We state the limits plainly — n = 46 careers, tracking data 2019–25 only — and pre-register a forward replication for 2026–27.

The deterrence framing here runs underneath the live Resolve NBA projections, where center value is priced on rim suppression rather than block totals.
