First quarter, your jumper is pure. Fourth quarter, the identical shot dies on the front rim, and it keeps dying there until the buzzer. Your form didn't change in forty minutes. Your fuel did — and it drained from exactly the place you'd never think to look.

Fatigue takes the dip first

When your body gets tired, it starts economizing, and it economizes quietly. The first expense it cuts is the deepest one: the dip. Fresh, your hips sink until your knees bend to around 115 to 120 degrees — the sweet spot where the legs load fully and the shot gets its power. Tired, the body shaves that load down degree by degree. You still dip. It still feels like your dip. But the spring is compressing less, storing less, delivering less.

Here's the cruel part: your arms can't tell. The shot feels the same leaving your hand, because the missing energy disappeared below your waist before the arm ever got involved. So the ball flies the same shape, just shorter — front rim, front rim, front rim — and you respond by aiming harder, which fixes nothing because aim was never the leak. Short is an energy miss, and in the fourth quarter the energy story is always the legs.

This is also why late-game free throws wander. The line hasn't moved, but the legs delivering you there have.

Seeing the fade

The fade is invisible from the inside and obvious on film. Capture a clip of your shot fresh and another one gassed, and CoachVision will show you the knee-bend gap between them — fatigue becomes a measurable number before it becomes a cold fourth quarter, which also tells you exactly how much dip you need to consciously restore when your legs start lying to you.

But awareness alone doesn't hold up at the line with two minutes left. You have to rehearse being tired, and the drill for that is FT Routine Under Fatigue.

Sprint a full suicide — baseline to near free-throw line and back, half court and back, far free-throw line and back, end to end and back. Then walk to the line and shoot two free throws with your exact routine, unabridged: every dribble, the breath, the settled beat, and — this is the fourth-quarter part — a complete, deliberate dip. Sink the hips fully even though your legs are begging for the shallow version. That's one round. Do five rounds and keep your score out of ten.

The drill works because game free throws are tired free throws; nobody earns trips to the line while fresh. Every round teaches your body that the full leg load is non-negotiable, especially when it's expensive.

Track the tired score week over week. The day it matches your fresh number, the fourth quarter stops being a different game.

Legs that have rehearsed being empty don't panic when it happens for real — train tired on purpose, and late-game shots start reaching home again.
