What That Flag Was For

A flag goes down forty yards away, the official says a word you don't catch, and everyone around you reacts before you've worked out which team it went against.

It took me longer than I'd like to admit to stop guessing from the crowd. The good news is that you don't need to learn a rulebook — you need to learn one distinction and about ten words, and after that most of a Saturday makes sense.

The short version

There are two kinds of foul.

Technical fouls are the lesser ones. If the offending team didn't have the ball, the other team just gets it. If they did have the ball, the player sits for 30 seconds, non-releasable.

Personal fouls are the serious ones — safety and sportsmanship. One, two or three minutes in the box, at the official's discretion, and at the youth level all of that time is non-releasable, meaning a goal doesn't end it.

That last word is the one that matters most for your goalie, and it changes when he reaches high school.

The technical fouls you'll see

These are the "somebody gained an unfair advantage" calls. Under the youth rules they are:

Holding — restraining an opponent with stick or body when he isn't entitled to. Pushing — exactly what it sounds like, from behind or otherwise illegally. Interference — impeding a player who isn't in possession and isn't within range of a loose ball. Warding off — the ball carrier using his free hand or arm to fend off a defender. Kids do this constantly and it surprises parents every time. Illegal offensive screening — setting a moving or illegal pick. Illegal procedure — the catch-all for delay of game, leaving the box early, a helmet coming off, that sort of thing. Withholding the ball from play — lying on it, trapping it, refusing to let it come loose. Crease violations and goalkeeper interference — the ones that belong to your kid, below. Conduct foul and misconduct — behavior calls.

The personal fouls you'll see

The serious list, and these are the ones that put a team man-down:

Slashing — striking an opponent anywhere on the body with the stick, except while genuinely passing, shooting or scooping. The gloved hand counts as part of the stick, unless it's on the ground. Cross-check — checking with the shaft between the hands. Illegal body check, including anything involving the head or neck. Tripping — obstructing at or below the waist with stick, hands, arms, feet or legs. Worth knowing: if a legal stick check causes an opponent to trip over his own crosse, that's not a foul. Targeting — deliberately taking aim at an opponent's head or neck, or at a defenseless player. Three minutes and an ejection. Unnecessary roughness — excessively violent contact, a punching check with the glove, or a take-out check. Illegal crosse or illegal equipment. Unsportsmanlike conduct.

Three personal fouls, or five minutes of personal-foul time, and a player is out of the game.

The three that are specifically about your goalie

Worth knowing cold, because they come up every game.

Goalkeeper interference. Opponents may not contact your goalie or his crosse. Under the youth rules that protection applies even when he doesn't have the ball. The one exception: if the ball is loose and he extends his stick outside the crease, that stick may be checked — but once he has possession, it may not be.

Crease violations. Offensive players may not enter the crease at any time. They can reach a stick in for a loose ball, but they can't contact your kid or his stick doing it.

The defender-in-the-crease rule. Only a properly equipped goalkeeper may enter the crease intending to block a shot. A defender who does it stops play — unless a shot is already in flight, which is allowed to finish. First offense is a technical foul; do it again and it becomes unsportsmanlike conduct.

And one that isn't a foul against anyone else, just a count he lives under: four seconds with possession in the crease, at every level from youth through college, with no grace period.

What each one means for him

This is the part that turns rules into something useful from a sideline.

When his team goes man-down, his job changes. More shooters than defenders, shorter possessions, and at the youth level the penalty runs its full length no matter what — so he knows exactly how long he's holding out. That changes in high school, where many penalties become releasable and a goal ends the kill, which makes every man-down save worth more and every goal worth more too.

When the other team goes man-down, his clear becomes the whole thing. Get it out fast and his team has an extra man for the whole possession.

When the flag is for something around his crease, he gets the ball. The most useful thing you can do is notice whether he restarts quickly or stands there waiting to be told.

A few things worth avoiding

Try not to referee from the sideline. Beyond what it teaches him — that the result belonged to somebody else — you're forty yards away and the official isn't.

Go easy on assuming a flag means someone did something wrong to your kid. Most flags are ordinary lacrosse, and a lot of them are against his own team.

And don't learn the rules in order to grade him more precisely. Learn them so you can see the good things he did on a day the score didn't cooperate.

The cheat sheet

Technical foul: minor, loss of ball or thirty seconds. Personal foul: serious, one to three minutes, non-releasable in youth ball. Anything involving his crease or his stick is probably in his favor.

That's genuinely most of it.
