The Wobbly Death
When a pass wobbles, two forces destroy it at once. The tumbling exposes the ball's maximum cross-section, massively increasing drag. Uneven air pressure on the wobbling surface also shoves the ball sideways.

A baseball pitcher bends a curveball with sidespin, using the Magnus effect — air deflected by the spinning surface pushes the ball sideways. A football barely does this. Its spin runs along the long axis, like a drill bit, not across a smooth round face.
