Prof. Scott Raiola
Football 101
Scoring Basics...
The goal of football is to score more points than your opponent. Points can be scored in a few ways...
Touchdown
(6 pts) - scored when you run OR catch the ball in the opponent's end zone
Field Goal
(3 pts) - Scored by kicking the ball off the ground and through the uprights (
aka field goal posts
)
Extra Point
(1 pt, duh!) - after scoring a touchdown (
TD
), the team is given a chance to kick a short field goal for one additional point
Safety
(2 pts) - Scored when the defense tackles an offensive player with the ball in their OWN endzone
Video Examples
Two Point Conversion
(2 pts, duh!) - after scoring a TD, INSTEAD of kicking an extra point, the team can try to score another TD from the 2 1/2 yard line. This time its only worth 2 pts though!
Touchdown
(running)! Vikings score
6 points
and can now either kick an
extra point
OR

go for a
two point conversion
Field Goal
! Indianapolis (white team) wins the game by
3 points
Safety
! TCU (black team) gets
2 points
for tackling the Quarterback of USC in their own end zone with the ball. To make things worse, USC would also have to kick the ball off to TCU on the next play
What Happens After Someone Scores?
After a Touchdown
- The scoring team attempts an extra point or two point conversion. Then, whether they are successful or not, they kick the ball off to the other team
After a Safety
- The team who was tackled with the ball (NOT THE SCORING TEAM) must kick the ball off to the team who scored the safety
After a Field Goal
- The scoring team must kick the ball off to the other team. If the field goal is MISSED however, the other team gets the ball from the kicking spot.
Possession Changes
Kickoff
- Kickoffs take place at the beginning of each half and after every scoring play. One team kicks the ball as far as possible and the other team tries to run the ball in the opposite direction
Here USC (white) kicks the ball to Oregon (dark green)
Turnover on Downs
- In order to keep possession, the team with the ball must move the ball at least 10 yards every 4 plays (aka downs). If after 4 plays/downs the team hasn't moved the ball 10 yards, they give the ball up to the other team at that spot on the field.
How do teams move the ball?
In order to keep possession of the ball, the
OFFENSE
must move the ball forward at least 10 yards every 4 plays. These "plays" are called "
downs
".

Every time the ball moves 10 yards, the downs are reset

If the
DEFENSE
stops the
OFFENSE
from gaining 10 yards after 4
downs
, the ball goes to the other team. This is known as a "
turnover on downs
"
Who Has the Ball?
The team with possession of the ball is known as the
OFFENSE
The team trying to stop the ball from moving forward is known as the
DEFENSE
Down & Distance
: This is a way to keep track of what down it is and how many more yards the offense needs to gain to get another set of downs
1st & 10 = 1st down, 10 yards to gain
3rd & 2 = 3rd down, 2 yards to gain
Possession Changes (cont)
Punt
- If the offense thinks they won't be able to get 10 yards on 4th down, they can elect to kick the ball to the other team. The goal of the punt is to give the other team the ball as far away from the end zone as possible. A punt is kicked as a "drop kick" rather than being kicked off the ground
Fumble
- When an offensive player drops the ball while running, the defense may pick it up and gain possession for their team
Interception
- This happens when a defensive player catches a ball that is being thrown to an offensive player
Player Set Up
OFFENSE
DEFENSE
"
Line of scrimmage
" - Imaginary line that divides the offense and defense. Runs the width of the ball across the field. No player (offense or defense can cross the line until the ball is snapped and the play is started
*11 players on the field

*Must remain behind line of scrimmage until ball is snapped

*Must remain still until ball is snapped/hiked
* 11 players on the field

* Can move and shift around but can't cross line of scrimmage until ball is snapped/hiked
notice line of scrimmage here
Common Penalties
Penalties are indicated using a
yellow flag
thrown by an official
Holding
- when an offensive player holds a defensive player (usually a jersey) and prevents them from moving
Offsides
- when a defensive player crosses the line of scrimmage before the ball is snapped
False Start
- when an offensive player moves before the ball is snapped
Facemask
- when a defensive player grabs the helmet of an offensive player
Delay of Game
- when the offense takes too long to start a play
