Hartenstein slots into OKC’s frontcourt, likely sharing time with Holmgren. He provides solid rebounds, blocking ability, and occasional scoring with a floor near Top-100. The upside depends on minutes and how the Thunder deploy their bigs, but a 26–27 minute baseline yields consistent value.

Hartenstein is praised as a mobile, defensive, pass-first center with a crafty post game. His 11.2 PPG, 10.7 RPG, and 3.8 APG last season show two-way value; the $28.5M 2026-27 club option and Holmgren’s rise could complicate his Thunder future.

Hartenstein’s presence in the Thunder’s core provides size and versatility, supplementing Holmgren and Shai as OKC chases another deep run. His role is a factor in how OKC handles Dallas’ interior presence and the overall depth of OKC’s frontline rotation.

Hartenstein’s inside presence and minutes offer reliable fantasy fodder in rebounds and blocks. Included in the Thunder’s top-100, he’s a dependable big who can contribute steady boards and blocks while Kieling OKC’s spacing with Williams and Holmgren. His role provides a solid floor for fantasy managers seeking consistency.

Hartenstein’s mobility, screening, and playmaking bolster the Thunder’s frontcourt. His fit with Holmgren provides a versatile rim-protecting and decision-making tandem, with health and chemistry key to sustaining upgraded defense and efficient attack.
