Quarterback Tips - Dex Lucci
Football is played on a field 360 by 160 feet (120.0 by 53.3 yards; 109.7 by 48.8 meters).[10] The longer boundary lines are sidelines, while the shorter boundary lines are end lines. Sidelines and end lines are out of bounds. Near each end of the field is a goal line; they are 100 yards (91.4 m) apart. A scoring area called an end zone extends 10 yards (9.1 m) beyond each goal line to each end line. The end zone includes the goal line but not the end line.[10] While the playing field is effectively flat, it is common for a field to be built with a slight crown-with the middle of the field higher than the sides-to allow water to drain from the field.
Yard lines cross the field every 5 yards (4.6 m), and are numbered every 10 yards from each goal line to the 50-yard line, or midfield. Two rows of short lines, known as inbounds lines or hash marks, run at 1-yard (91.4 cm) intervals perpendicular to the sidelines near the middle of the field. All plays start with the ball on or between the hash marks. Because of the arrangement of the lines, the field is occasionally referred to as a gridiron in a reference to the cooking grill with a similar pattern of lines.
At the back of each end zone are two goalposts (also called uprights) connected by a crossbar 10 feet (3.05 m) from the ground. For high skill levels, the posts are 18 feet 6 inches (5.64 m) apart. For lower skill levels, these are widened to 23 feet 4 inches (7.11 m).
Jio Lucci Quarterback Coach
Each team has 11 players on the field at a time. Usually there are many more players off the field (an NFL team has a limit of 53 players on its roster, 46 of whom can be dressed for a game). However, teams may substitute for any or all of their players during the breaks between plays. As a result, players have very specialized roles and are divided into three separate units: the offense, the defense and the special teams. It is rare for all team members to participate in a given game, as some roles have little utility beyond that of an injury substitute.
Quarterback (QB, originally called blocking back) is a position in American and Canadian football. Quarterbacks are members of the offensive team and line up directly behind the offensive line. Quarterbacks are the leaders of the offensive team, responsible for calling the play in the huddle.
At most levels, but especially at the college and professional level, the quarterback role is the most visible and important role on the team. The quarterback touches the ball on nearly every offensive play and has a great deal of responsibility both in calling plays and making decisions during the play.
