American football rulings under review.

Where American football rulings get messy

1. Catch or incomplete: control and feet are only part of the test; the player may still need time or an act that completes the catch.
2. Holding and illegal contact: officials separate ordinary hand fighting from material restriction, and receiver-contact rules can change once the passer leaves the pocket or the ball is thrown.
3. Intentional grounding: throwaways depend on pressure, eligible receivers, the tackle-box area, the line of scrimmage, and clock-stopping spike exceptions.
4. Illegal forward passes: officials check pass direction, the passer's release point, whether a forward pass was already thrown, and whether possession changed.
5. Ineligible receivers downfield: passing fouls can turn on a lineman's location at release, whether the pass crossed the line, and whether a screen-pass exception applies.
6. Pre-snap movement: false starts, encroachment, neutral zone infractions, and offside turn on who moved first, whether the neutral zone was entered, and whether contact or an immediate reaction occurred.
7. Pass interference: both players can compete for the ball, so officials look for meaningful restriction rather than ordinary contact.
8. Protected-player contact: timing, target area, and method can turn a hard but legal hit into roughing, targeting, or unnecessary roughness.
9. Kickoff outcomes: fair-catch and touchback consequences vary by rulebook, especially under college-style and modern NFL kickoff rules.
10. Punt spots: downed kicks, first touching, muffs, goal-line saves, and touchbacks can all change where the receiving team starts.
11. Dynamic kickoff zones: NFL kickoff results now turn on the landing zone, setup zone, movement restrictions, and declared onside-kick status.
12. Overtime possession: NFL overtime depends on possession opportunity and postseason status, while college football uses matching possessions and later 2-point attempts.
13. Down and distance: first-down rulings depend on the official spot of the ball, the line to gain, and whether a penalty repeats, counts, or resets the down.
14. Clock stoppages: timing rulings depend on why the clock stopped, whether it restarts on the ready-for-play or snap, and whether a late-half runoff applies.
15. Delay of game: play-clock rulings depend on when the count started, whether the ball was snapped or kicked in time, and whether a timeout or reset was available.
16. Substitutions: player-count rulings depend on whether the offense substituted, whether the defense had time to match, and whether the extra player was in the huddle, formation, or on the field at the snap.
17. Fumbles and recoveries: loose-ball rulings depend on possession, whether the player was down, who recovered, and whether special advancement or end-zone rules apply.
18. Scoring plays: touchdowns, field goals, tries, safeties, and touchbacks depend on possession, the goal line, force, and code-specific enforcement.
19. Safety rulings: two-point safeties turn on force, possession, end-zone fouls, forward progress, and whether a momentum or touchback exception applies.
20. Touchdowns and tries: extra points and two-point conversions depend on the try spot, possession, completed catches, defensive-return rules, and penalty timing.
21. Missed field goals: the result depends on whether the kick crossed the line, was touched, became dead, stayed returnable, or uses a special missed-kick spot.
