Starting a game
To decide which team starts attacking and defending what there is a drawing by a
coin, a coin toss, with the presence of one or more players from each team (usually
the captains). The team winning the toss may choose to start the game or for the
start of the second half (declining your choice):
• Designate the team performing the kickoff.
• Designate which side of the field will defend his team.
The losing team will hold its election flown at half the winner is not selected.
The start of a game is marked by long kickoff return and a special teams play in
which a player of the attacking team (the kickoff returner) receives the ball, kicked
before the opponent as far as possible. The returner tries to haul back looking
forward the most yards you can by the race. If presented with the opportunity to try
to reach the end zone at the other end for a touchdown, but commonly is

point where the returner has been demolished.
Down

of the play. The two basic ways to develop a play in football are with ground
attacks (carrying the ball) and / or with air strikes (throwing passes).
The end of a play is conditioned to different circumstances, being the common
when a pass is unsuccessful (incomplete pass), when the player carrying the ball is
thrown by an opponent within the playing field or when out of it by the bands either
by choice or by being pushed by an opponent.
If a player lands without any opposing player has it down or at least touched, can
get up and continue the play. If one falls and rises before an opposing player
touches it then the play ends because of a down by contact.
