"Offensive tactics in set pieces. ...
Throw-ins[edit]
How throw-ins are best handled depends on where it is:
(1) In one's own half the aim of a throw-in may be to retain possession in order to build up the next attack. The throw may or may not go toward the opponents' goal; the most unmarked player may be a full-back who is behind the ball. Such a throw followed by a quickly taken 'switch' pass can be an effective tactic. Under pressure however, the ball is often thrown up the line, toward the opponents' goal line to gain as much ground as possible.
(2) If the thrower is unmarked, a simple tactic is to take a short throw to the feet or chest of a marked player who immediately returns the ball to the thrower.
(3) In the last third of the pitch a player with a long throw can put pressure onto the defenders by throwing the ball deep into the opponents' penalty area, resulting in somewhat similar tactics to a corner kick situation, but with the added advantage of avoiding the offside trap, as an attacking player cannot be offside from a throw in. ...
Goal kicks.
A goal kick is an important 'set piece' that will occur many times in a game and yet few teams practice it. If taken quickly the kick may be taken short to a full-back who has run into a wide position. Although this may gain little ground it retains the all-important possession of the ball. A longer kick to the midfield is more common and it is vital that the midfield unit are in a position to receive it.
Corners.
A corner kick (or "corner") is a real goal scoring opportunity and it is essential to know who is the best at taking a good corner from both the left and right side of the pitch. A good corner will be aimed high across the goal and may be 'bent' towards or away from the goal. At least one of the forwards should be on or close to the goal line when the kick is taken.
Another tactic on a corner is to let the best shooter stay in the back "trash" position and have the defence worried about those up front. The player taking the corner kick makes a small pass back to the trash shooter who has time and space to take a good shot." [Association football tactics and skills. Wikipedia]

"The goal line is the chalked or painted line dividing the end zone from the field of play in American football and Canadian football. It is the line that must be crossed in order to score a touchdown
If any part of the ball reaches any part of the imaginary vertical plane transected by this line while in-bounds and in possession of a player whose team is striving toward that end of the field, this is considered a touchdown and scores six points for the team whose player has advanced the ball to, or recovered the ball in, this position. This is in contrast with other sports like Association football and ice hockey, which require the puck or ball to pass completely over the goal line to count as a score.
If any member of the offensive team is downed while in possession of the ball behind his own team's goal line, this is called a safety and scores two points for the defensive team.
If, during the course of play, a loose ball travels past the goal line and is recovered within the end zone, then it is a touchdown if recovered by the kicking team, or a touchback if recovered and downed by the receiving team.
In the event of a kick recovered in one's own end zone, the entirety of the ball must pass the goal line in order for the ball to be considered in the field of play, and not a touchback." [Goal line (gridiron football). Wikipedia]
