The read
Over his last 10 games, Drey Jameson has gone over 1.5 K 2 of 10 decided times (20%) — versus 18% across the full season. His game-to-game K have been highly variable (σ ≈ 0.7), so short streaks can mislead. These are descriptive stats about past games, not predictions or betting advice.

Edge vs
Hit rate excludes pushes from the denominator. Confidence uses a 95% Wilson interval — a high recent rate on few games still reads as low confidence. Season over rate at this line: 18%.
