what you are probably referring to is the off side rule. That rule basically states that a player who receives a pass from his teamate has to be at least level with the second to last player on the opposing team. Counting the goalkeeper, this usually means that strikers have to be level with the opposing team's last defender not to be offside.

Fullback usually lines up closer to the quarterback, and on many occassions is the blocking back.  Halfbacks tend to be smaller and faster, and line up in the back of the I-formation.

It is regular term for old v-ball rule when you win on other team's serving game to take back the serving rights in order to win points.(on old rule, you don't get points on side-out, but only on your serving game) Now, Side-out becomes a history, but people may still apply it to a receiving game.

The Offside Rule and Offside Trap in Football(Soccer) \nIt is not an offence in itself to be in an offside position.\n\nA player is in an offside position if:\nhe is nearer to his opponents' goal line than both the ball and the second last opponent \nA player is not in an offside position if:\nhe is in his own half of the field of play \nhe is level with the second last opponent \nhe is level with the last two opponents \n\nCommiting an Offside Offence\nA player in an offside position is only penalised if, at the moment the ball touches or is played by one of his team, he is, in the opinion of the referee, involved in active play by:\ninterfering with play \ninterfering with an opponent \ngaining an advantage by being in that position \n\nNo Offence\nThere is no offside offence if a player receives the ball directly from:\na goal kick \na throw-in \na corner kick \n\nInfringements/Sanctions\nFor any offside offence, the referee awards an indirect free kick to the opposing team to be taken from the place where the infringement occurred.

A simple version of the offside rule in soccer\nwould be: \n\n1. A player is in an offside position if:\n   -he is nearer to his opponent's goal line\n    than both the ball and the second last opponent.\n\nA player is not in an offside position if:\n\n   - he is in his own half of the field\n   - he is level with the second last opponent\n   - he is level with the last two opponents\n\nNow a player in an offside position is only\npenalized if, at the moment the ball touches \nor is played by one of his team, he is, in the\nopinion of the referee, involved in active play\nby:\n\n- interfering with play\n- interfering with an opponent\n- gaining an advantage by being in that \n  position.\n\nIf the ball is received directly from\n a goal kick, throw-in and corner kick,\n there is no offside offence.\n\nThis is probably the simplest way of \nexplaining the offside rule in soccer.

If there are two legs (games played) then yes, like the person above said, it is the aggregate of both legs.\n\nIf there's only one game and the score looks like this:\n\nTeam Red  4 (3)\nTeam Blue 2 (1)\n\nThen this means that at the end of the first half, the score was Red Team 3 and Blue Team 1.\n\nThe parenthesis just mean the half-time score.

What makes the offside rule especially complicated is that a player can be in an "offside position" without being offside. Two things are necessary to be "offside":\n\n1st - The player must be in an "offside position" at the moment the ball is "played" by a teammate. To be in an "offside position", a player must be on the opponent's half of the field & closer to the opponent's goal line than both the ball & the second-last defender. A player is not in an offside position if he is on his own half of the field (i.e. the half his goalkeeper is on), or even with the second-to-last defender or the last 2 defenders. (The goalkeeper is usually the last defender, or one of the last two, but he might not be; the rules just refer to the last 2 defenders & don't mention the goalkeeper). This is often difficult to call. (For example, if a player is even with the Second Last Defender & thereby in an "onside position" but runs past the Second Last Defender a split second after his teammate makes a through pass. In this example, the player is not offside because he was in an onside position at the moment the ball was played.)\n\n2nd - The player must be involved in "active play" by either:\n\n    * gaining an advantage by being in an offside position, or\n\n    * interfering with play, or\n\n    * interfering with an opponent

Yes they can,  However this has to be ageed between both teams and would only be if the game was a friendly.  I've done it. \n\nAlso in many testimonail matches for a player It has been known that they play one half for one team then swap at half time and play for the other side.\n\nIn a normal domestic league game the answer would be no.

I think the score in brackets means the score line at half time.

The usual practice is for the player to play a half with each side.

its to ensure players are 10 yards from the ball when a penalty is taken.\n\nThis is worked on the radius from the penalty spot as the edge of the 16 yard box is closer to the penalty spot directly behind it so when a penalty is taken, players are not allowed in the semi circle.

Well the simple rules, are you are not allowed to pass the ball forwards, only backwards, taclking is always better if the person tackles his/her rival from underneath the waste, even better by the kneew, cuz its easier that they fall that way, and the point is to score a touch done withouth them tackling you, if they do drop the ball by your side so that maybe someone from ur team can get eat, only through it when there is someone from you team in sight

If you are not interfering with the play, it is not off-sides. But, even if you don't go for the ball, but you are impeding a defender or the goalkeeper it can be considered off-sides because then you would be interfering with the play.

Kuteyk has it right.\n\nIn Hockey if the player is past the blue line without the puck then passed to him he is OFFsides. But if he passes the blue line WITH the puck he is ON sides.\n\nIn Soccer, if the player is between the last defender and the the Goalie without the ball he is OFFsides, but if the player is  lined up next to the defender then the ball is passed to him he is ONsides.

A player is an offside position if he is nearer the opponents' goal line than both the ball and the second-to-last opponent.\n(Exceptions: the player is in his own half of the field, it is a throw-in, goal-kick, or corner kick).\n\nIt is an offsides offence if a player is in an offside position (as defined above) and:\nthe ball is played or touched by a teammate; and\nthe player interferes with the play, or an opponent, or gains some advantage from being in an offsides position.
