Basics of American Football.
~ You have 11 guys on each side of the ball. One side is trying to score points, the other is trying to stop them.
~ The field is 100 yards long, with two endzones on each side of the field that are roughly 10 yards long each.
~ Penalties. There are various various penalties. I'd have to find a rule book to show you instead of trying to type out everyone I can think of, it'd be a LONG list.
Scoring Points
Touchdown - 6 points.
Extra point kick (after TD) - 1 point.
OR
A team can run/throw the ball back into the endzone on a special play and receive two points instead of one.
Field Goal - 3 points.
Safety - 2 points for defensive team. A safety is basically when the Defense
sacks the offenses' quarterback in his own endzone.
OFFENSE
The ones trying to score are called the offense. This side consists of a quarterback and center (The center snaps the ball off the line of scrimmage to the Quarterback - QB), running backs, offensive line (quarter back protectors... basically), full backs and receivers.
The object of the offense is to get the ball into the endzone for the 6 points. They can do this by throwing (to the receivers) or running the ball (via a handoff from the QB to the running back/fullback).
The main objective is to drive at least 10 yards for each play. Each ten yards gained gives you a new set of downs. First down the best down, 2nd down means a play failed to gain 10 yards/Touchdown. 3rd down is after the second failed attempt, 4th down is the final play of that outting.
Most of the time, you will see who is called the Punter come out to kick the ball away to the other team. This objective drives the ball further down the field to give the receiving team a further (worse) field position. On plays where time is a factor (nearing end of game or 2nd quarter in some cases), teams may go for a play to reach 1st down while on their 4th down. If they fail to get their first down, it's called a turnover on downs. The opposing team gets the ball at the previous line of scrimmage.
DEFENSE
The Defenses' goal is to stop the offense from getting first downs leading to a touchdown/field goal by any legal means necessary (legality as in courts and NFL rules).
A
QB sack is when the QB on the offensive team is taken down behind the line of scrimmage by a defensive player.
An
Interception is when a member of the defense catches the ball in the air thrown by the offenses' quarterback. He is then free to run the opposite way until he either scores or is stopped.
A
Fumble is when an offensive (and/or) defensive player is running with the ball and it pops out before his knee or shoulder is on the ground. It is still a live play at this point, and whoever is downed on the field with the ball in control has the ball.
SPECIAL TEAMS
Special Teams is a division which comes out on the field to run back/block a punt, kick off or field goal.
~ On a
punt or kick-off, it's the receiving teams' goal to provide blocking for their receiver (person who caught the kick) to allow him to try to run back for a better field position or a touchdown. (look up Devon Hester, he's very good at running back for TDs).
~ The kicking teams' goal is to stop the receiver of the kick as far back as possible.
~ The 20 yard lines are where balls roll out the back of or are caught in the endzone and knealed down on are spotted.
~ A kick that goes out of bounds untouched outside the endzone are spotted where it went out of bounds at. (say it went out on the 37 yard line, the line of scrimmage starts at the 37 yard line).
~
Field goals usually are spotted at the 29 yard line (19 yard line + the 10 yards distance the endzone covers). However, on 4th down situations, the ball is spotted at the current line of scrimmage where the offensive had failed to move the downs closer to their endzone (goal line).
A team will have both a Punter and a Kicker on their special teams.
Example: Indianapolis Colts punter/kick off guy is Hunter Smith and their Field goal kicker is Adam Vinatieri.
I have personally seen 60 yard field goal kicks go right down the center of the uprights. (that is one HELL of a kick)
Anything else, just ask. Donnie, me and probably a few others will be able to answer anything.
