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

Ron Harper Jr.’s early season was defined by brutal shooting slumps and an inability to find a consistent rhythm off the bench. He frequently forced the issue, leading to disastrous outings like his appearance on 02/08 vs NYK. During that game, his complete offensive disjointedness and poor shot selection resulted in a catastrophic -7.6 impact score. However, he occasionally delivered massive value without needing high volume. On 11/12 vs MEM, Harper managed a +4.0 impact score while scoring just 6 points, creating instant momentum by knocking down a pair of crucial triples in a four-minute micro-burst. He finally found his stroke late in the stretch on 03/10 vs SAS. Blistering perimeter efficiency yielded 22 points, anchoring the offense and earning him a stellar +6.7 impact score.

IMPACT TIMELINE

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

PATTERNS

Boom-or-bust player. Jr.'s impact swings wildly relative to his average — some nights dominant, others invisible. Scoring varies by ~5 points per game.

Streaky shooter — only cracks 45% from the field in 33% of games. Efficiency is all over the place night-to-night.

Average defender. Jr. doesn't hurt you defensively, but he's not making opponents uncomfortable either.

Flat trajectory all season — first-half impact -1.1, second-half -1.1. No major shifts, which fits with the overall steadiness.

In a rough stretch — 5 straight games with negative impact. Longest cold streak this season: 5 games.
