Splash Arc Lab: Stephen Curry 3-Point Trajectory Simulator
Analyze how launch angle, backspin, shot distance, and defender closeout affect rim clearance and swish probability. Inspired by Stephen Curry's historic 2-year, $116M extension with Golden State.

The Science of Stephen Curry's Shot
Standard basketball rims have an 18-inch diameter, while an official NBA basketball is 9.5 inches across. A ball approaching vertically has 100% of the rim's opening available. At a flat 35° entry angle, the effective target shrinks to just 10.3 inches—leaving barely 0.8 inches of clearance.
Curry launches at an apex angle between 53° and 55°, resulting in a steep 45° to 48° entry angle into the cylinder. This expands the geometric target area by roughly 20%, forgiving minor lateral or depth release deviations.
Contract Valuation & Shot Economics
In August 2024, Stephen Curry agreed to a 1-year extension that solidified his commitment through 2026-27, guaranteeing over $116 million across the upcoming seasons. Why does Golden State pay $58M+ per year for a guard in his late 30s?
Curry's gravity distorts opposing defenses at 30+ feet. His true-shooting percentage (.640+ career average) generates unmatched offensive efficiency, avoiding the punitive 2nd-apron luxury tax drag of non-performing roster assets.
How does defender contest alter release velocity?
When an NBA defender closes within 3 feet with an outstretched hand (8.5 to 9.0 ft contest height), the shooter must elevate their release point by 4 to 6 inches and increase release angle by 2° to 3° to avoid block trajectories. This requires an extra 0.4 m/s of initial launch velocity to reach the rim.
What is backspin's role in the "soft bounce"?
Curry averages 2.5 to 3.0 revolutions of backspin per shot. Upon rim contact, the friction between the spinning leather and steel cancels horizontal forward momentum, keeping rebounds close to the cylinder for second-chance rolls.
Can I export the session data?
