Football is a contact sport that involves running, catching, and throwing the ball. Players are separated into offensive and defensive positions. Offensive coaches manage the players in their positions; defensive coaches supervise the players in their positions. This division helps teams stay organized and allows players to easily transition between positions. Football has many rules.
Penalties occur when a team violates a rule. Typically, penalties move the football toward or away from the opponent’s endzone. However, in some cases, they give the offense an automatic first down. Other penalties involve blocking, illegal contact, and delaying the game. The first down is when an offensive player advances the ball 10 yards or more.
The game was originally played in England in the 19th century. Football was initially called “folk football” and was played with local customs and minimum rules. As time passed, new rules were developed to prevent players from getting injured. By the 1950s, the NFL had become a major professional league. Today, the NFL is one of the most watched sports in the United States.
Football teams consist of 45 to 50 players, with a different number of players for each position. During a regular season, the team will play 16 games. They then get a week off. After the regular season, the team will play a playoff tournament.
