Sideline freeze-frame! Two feet in, ball held — was it a catch?
You're the sideline referee! Watch the throw, freeze-frame it, call it — then say which part of the rule decided it. Six plays, twelve calls in all.
For grown-ups: the NFL catch rule judged visually — two feet in bounds, the sideline itself out of bounds, toe-taps, control of the ball, surviving the ground, the football move, and the one-foot college rule named explicitly per play. Boundary reasoning and rule logic. Replay booth tightens the sideline margin to a single unit. Ages 6–10.
