what does dominate the line of scrimmage mean?
467554
This is an American football question.  The line of scrimmage is the point where the ball is placed at the beginning of a play.  The offensive line tries to block the defensive line from being able to sack the quarterback or open a hole for the running back to run through (depending on if the current play is a run or pass play).  So, both sides try to "dominate" on each play and, if one team's line is far and away better than the other team's counterpart, that team has dominated the line of scrimmage for the game.

Illegal Substitution: It's illegal to break the huddle with 12 players. This happens from time to time if a player comes into the game without properly informing the player he's replacing. \n\nIllegal Motion: A reciver or back is allowed to be in motion prior to the snap as long as he isn't moving towards the line of scrimmage. When he is, illegal motion is called.

OK - I don't claim to be an expert, but here is my version of what makes them different in terms of rules.\n\nLeague does not allow the ref to "play the advantage" as much. This means if someone does something wrong (such as a forward pass) the ref has to stop and penalise in league. Not so in union. The ref may let it continue on to see if the other team ends up in a better advantage than the other.\n\nRuck and Mauls - OK I don't get this with union. Something about depending on whether the guy with the ball gets rolled over or something, he has to release the ball whilst he is being tackled.\n\nScrums - actually still a point to this in union. In league a scrum very rarely results in a turnover in possession because the rules basically state that players aren't allowed to push in the scrum. In union they can.\n\nUnion has lineouts. Once again - I don't really understand union so I don't know why they do this. but basically each team lines up and one guy throws the ball and both teams throw one of their guys in the air anf try to catch it.

a team is in possession if they are controlling the play of the ball, dribbling it, or passing it to another member of the team.\n\nwhen the other team intercepts a pass or tackles the ball away and takes control of the ball, then posession switches.\n\nyou just keep track of start/stop times for possession for each team and add them up.  note that you really only have to track one team, since the possession for the other team is the total elapsed time minus the possession for the other team. :)

There are basically two teams within a team... the forwards and the backs. The forwards are those players that you see packingi nto a scrum. They are made up by the props, hooker, second rowers and lock. The props are their primarily to try and barge through the opposition defense as well as complete some tackiling. The hooker is responsible for getting to each play the ball to distribute the ball quickly and accurately. Back when scrums were a contest between the two teams he would have to "hook" for the ball when it was fed in. The second row are in the second row of the scrum and their primary job is to act defensively and to assist the props breaking the opposition line whn in attack. The lock forward "locks" the scrum and also assists the other forwards but is usually usd to assist the backs as well in defence. The backs are made up by the half, five-eight, two centres, two wingers and a fullback. The half back feeds the scrum and is usually responsible for directing the attacking play of their team. Similarly the five-eigth is also used to generate attacking moves and usually has good kicking and passing skills so that they can easily put other players into gaps. The two centres are usually fast, agile plyers who are able to capitalise on be put through gaps and improving the teams position, as are the two wingers. The fullback is able to support the backline at any of these points, providing and extra man or "overlap". In defense the wingers drop back to field opposition kicks and to support the fullback in attack as they run a kick back. In defense the fullback can instruct the densive line where there might be gaps to be filled, and is also used as the last line of defense against oppostion line breaks or kicks.

Counter\na running play in which the running back will take a step in the opposite direction of the play, only to get the handoff in the other direction. Weak side linemen will sometimes pull and lead the back downfield (sometimes called a counter trap), but not necessarily. The play is designed to get the defense to flow away from the action for a few steps, allowing more room for the running back.

Well, in the NFL, I think you can make contact within five yards of the line of scrimmage. So I guess you can push him to get an advantage on your route. I'm not sure if you can actually push him down though.  And the rules might be completely different for 2-touch football compared to tackle, just like floor hockey and ice hockey have different rules.

As in that scene in 'Remember the Titans'?\n\nThey were referring to the strong side of the Defense.  The strong side is where the offense has a tight-end in for an extra blocker.  It's usually where the bigger linebacker or extra safety is lined-up.

Okay, I asked what you specifically wanted to know about in Rugby, and you mentioned scrums and scoring points.\n\nScrums are used to restart play after the ball is not in play but is not because a penalty, out-of-bounds, or score. This is for accidental things such as a knock-on or forward pass. A scrum can be chosen on more serious infractions if it helps the team.\nThe other team gets to put the ball into the scrum on a re-do if the original scrum is turned 90 degrees.\nPoints can be scored in multiple ways:\n* Penalty kick - when a penalty is awarded a team, the kicker has the option of "kicking for goal". This is worth 3 points\n* A drop goal - when you kick the ball through the goal posts while the ball is in play. Worth 3 points\n* A try - when you touch the ball down to the ground in the goal area - worth 5 points\n* A conversion - you get one chance to kick the ball through the goal posts after a try, and a successful attempt brings you 2 points
