About this model: Net Impact can't measure floor spacing, help defense rotations, or playmaking gravity — so wings and guards are slightly undervalued vs bigs. How Net Impact works

THE SEASON SO FAR

Amari Williams spent the bulk of his first twenty appearances battling the harsh reality of being a complete offensive liability in a spacing-obsessed league. When given a rare starting nod on Jan 28 vs ATL, his glaring inability to finish basic looks crippled the half-court offense. Despite grabbing six rebounds, he posted a disastrous -7.2 impact score because his limitations forced his teammates to play four-on-five. Short, energetic bursts yielded much better results. During a five-minute cameo on Jan 24 vs BKN, Williams posted a stellar +4.3 impact score. He only scored three points, but his mistake-free execution and stout rim deterrence made him an overwhelming net positive. His ceiling as a situational anchor appeared on Jan 27 vs POR, where his modest nine points in 26 minutes were offset by a massive +6.0 defensive rating and a +0.4 overall impact score earned by effectively walling off the paint against driving guards.

IMPACT TIMELINE

Game-by-game performance vs average. Green = above average, red = below.
