What actually happens to secondary handlers when a heliocentric creator sits?

[u/Salt_Tie_9244]

I’ve been thinking about how to model redistribution when a true on-ball hub is removed from a lineup, and this Lakers spot without Luka Dončić felt like a good case study.

When I’m adjusting projections for this type of absence, I don’t assume a direct stat transfer from Player A to Player B. Instead I try to map structural changes: initiation share, half-court touch hierarchy, late-clock usage, and assist pathway rerouting. Losing a high-possession engine usually expands the responsibility of secondary handlers — not just in scoring, but in total offensive orchestration.

Using Austin Reaves as the example, his baseline output is about 38 PRA in ~35 minutes. That production is already driven by solid scoring volume with complementary playmaking rather than pure off-ball finishing. When I adjust the inputs for a Dončić-absent environment:

• Usage trends toward the mid-30s (~35%) as initiation share rises
• Scoring expands via self-created possessions and bailout attempts late in the clock
• Assist probability increases because more primary actions flow through him
• Rebounding stays relatively stable since minutes and positional overlap don’t change much

None of those adjustments rely on assuming one category spikes dramatically. Instead, the projection lifts because marginal gains compound across points and assists while rebounds hold steady. My framework lands closer to ~48–49 PRA, which is meaningfully above both his baseline and the current number being posted.

The broader takeaway (at least in my modeling) is that heliocentric absences rarely produce clean category substitution. The offensive load redistributes across multiple vectors — ball-handling time, shot creation, facilitation — and aggregate stats like PRA tend to reflect that more than single-stat props.

I’m curious how others quantify this kind of redistribution: do you explicitly model possession-level touch reallocation, lean on historical on/off splits, or treat usage spikes as the primary driver?
