What if…?
Without Isaiah Jackson, Indiana Pacers were 3.1 points per game better
38 games with him · 13 without, in 2025-26
3.1
points per game
The question
What would have changed if Isaiah Jackson had not played?
The evidence
Without Isaiah Jackson, Indiana Pacers were 3.1 points per game better
The fact
What actually happened, game by game, in 2025-26. None of this is an estimate.
With Isaiah Jackson in the box score
-8.53 points per game
38 games · 9-29 · 109.9 – 118.5
Without him
-5.38 points per game
13 games · 4-9 · 113.8 – 119.2
The assumptions
What we decided in order to answer. If an assumption does not hold for you, neither does the answer.
- That the 13 games without him represent a whole season without him.
- That opponent quality is spread evenly across both groups. We have not controlled for it.
- That other absences do not systematically coincide with his.
The estimated result
Arithmetic on the two figures above, nothing else: the per-game difference carried over a 82-game season.
- points of margin per game+3.15
- Across 82 games that is +258 points of accumulated margin.
FactDerivedAssumption
What this does not prove
- This does not say he is the cause. A team without its best player also changes rotation, opponent and schedule at the same time.
- It rests on 13 games without him. At that sample size, a couple of odd games move the number.
- It is not a forecast for next season: it is what happened in the one already played.
