Football has the most jargon of any major American sport, and the broadcast assumes you absorbed it through osmosis. Here's the stuff that actually decides games. Yes, the Hail Mary is the first one — naming a company after a play means we should probably explain it.

Hail Mary

A long, desperate pass thrown toward the end zone at the end of a half or game when nothing else will work. The quarterback heaves it as far as they can and prays someone on their team catches it. Hits about 10% of the time.

If you see the offense huddled with seconds left and they look somber, this is what's coming. Worth staying for — they're cinema.

Hail Mary coming. Three seconds left, no timeouts, down by four. This is the entire game on one throw.

Play-action

The quarterback fakes a handoff to a running back, then throws a pass. The fake makes the defense hesitate just long enough to open receivers downfield. Half of NFL passing is this trick.

When a long pass looks too easy, play-action is usually why. The defenders bit on the fake and got caught flat-footed.

Beautiful play-action. The linebackers stepped up and the safety lost his man.

Blitz

Instead of letting their linebackers (or defensive backs) drop into coverage, the defense sends them charging at the quarterback. High risk, high reward: either the QB gets sacked or someone's wide open downfield.

Blitzes are the defensive coach saying “we don't trust you to throw on us.”Watch the QB's face after one.

Six rushers on that blitz. Mahomes had less than two seconds.

Pick six

A defender intercepts a pass and runs it back for a touchdown. Six points the offense was about to score, now scored against them instead. The most demoralizing play in football.

14-point swing on one play. Watch the quarterback's sideline body language for the rest of the half.

Pick six. They were down by three, now they're up by four. Brutal swing.

Red zone

The 20 yards closest to the end zone. The field gets short, defenses get crowded, and scoring touchdowns is significantly harder than scoring from anywhere else. Teams that score well in the red zone tend to win.

When a drive stalls in the red zone and the team settles for a field goal, that's the moment fans get loud.

Stalled in the red zone. They take three points instead of seven. That hurts.

Two-minute drill

The hurry-up offense at the end of each half when the clock is enemy #1. Quick passes, spiking the ball to stop the clock, sprinting to the line. The most fun two minutes in football.

Great quarterbacks live for this. If the QB looks calm in a two-minute drill, the game might not be over.

1:42 left, no timeouts, down 4. Classic two-minute drill territory. Stay tuned.

Onside kick

Instead of kicking the ball deep, the kicker drops it short — at least 10 yards — and their own team tries to recover it. A trick play teams use when they're losing and need possession. Almost never works since recent rule changes.

If you see the kicker doing something weird at the line, this is it. Watch the scramble.

Onside kick coming. They're down 10. This is desperation.

Pass interference

A penalty for a defender grabbing, pushing, or otherwise illegally contacting a receiver before the ball arrives. The offense gets the ball at the spot of the foul, which is sometimes 50+ yards. The most game-changing penalty in football.

If a deep pass falls incomplete but a flag flies, the offense probably just got bailed out.

DPI on the deep ball. 42-yard penalty. The drive lives.
