SHL roster continuity beats coaching churn

Returning cores correlate with points share; wholesale coaching changes barely move team level.

52 team-seasons, SHL regular 2021/22–2024/25. MotherDuck-backed.

Chart values = mean points percentage.

Key findings

  • Returning-core share vs points%: r = 0.32.
  • Mean core age vs points%: r = −0.05 — age is not the lever in this window.
  • 19 coaching changes vs 29 keeps: mean Δ pts% −0.011 vs −0.005.
  • 2026/27 prior top four (not a lock): Frölunda, Växjö, Skellefteå, Rögle — aligned with 2025/26 grundserie table in the lake.
