Ineligible Receiver Downfield
In gridiron football, an ineligible receiver downfield, or an ineligible man downfield, is a penalty called against the offensive team when a forward pass is thrown while a player who is ineligible to receive a pass is beyond the line of scrimmage without blocking an opponent at the time of the pass. A player is determined ineligible based on his position at the time of the snap. When the ball is snapped, the offense is required to have no more than eleven players on the field, out of whom only six are eligible. On most plays, the eligible receivers include the quarterback, running backs, fullbacks, tight ends, and wide receivers, while the ineligible receivers are offensive linemen, including the center, offensive guards, and offensive tackles. However, in the National Football League, a quarterback is an ineligible receiver if he is directly under the center when he receives the snap. The rule varies among leagues. In college football, the NCAA allows ineligible receivers to ...

National Collegiate Athletic Association
The National Collegiate Athletic Association (NCAA) is a nonprofit organization that regulates student athletics among about 1,100 schools in the United States, Canada, and Puerto Rico. It also organizes the athletic programs of colleges and universities in the United States and Canada and helps over 500,000 college student athletes who compete annually in college sports. The organization is headquartered in Indianapolis, Indiana. Until 1957, the NCAA was a single division for all schools. That year, the NCAA split into the University Division and the College Division. In August 1973, the current three-division system of Division I, Division II, and Division III was adopted by the NCAA membership in a special convention. Under NCAA rules, Division I and Division II schools can offer scholarships to athletes for playing a sport. Division III schools may not offer any athletic scholarships. Generally, larger schools compete in Division I and smaller schools in II and III. ...

College Football
College football (french: Football universitaire) refers to gridiron football played by teams of student athletes. It was through college football play that American football rules first gained popularity in the United States. Unlike most other sports in North America, no official minor league farm organizations exist in American or Canadian football. Therefore, college football is generally considered to be the second tier of American and Canadian football; one step ahead of high school competition, and one step below professional competition (the NFL). In some areas of the US, especially the South and the Midwest, college football is more popular than professional football, and for much of the 20th century college football was seen as more prestigious. A player's performance in college football directly impacts his chances of playing professional football. The best collegiate players will typically declare for the professional draft after three to four years of colleg ...

Center (American Football)
Center or Centre (C) is a position in gridiron football. The center is the innermost lineman of the offensive line on a football team's offense. The center is also the player who passes (or "snaps") the ball between his legs to the quarterback at the start of each play. The importance of centers for a football team has increased, due to the re-emergence of 3–4 defenses. According to Baltimore Ravens general manager Ozzie Newsome, "you need to have somebody who can neutralize that nose tackle. If you don't, everything can get screwed up. Your running game won't be effective and you'll also have somebody in your quarterback's face on every play." Roles The center's first role is to pass the football to the quarterback. This exchange is called a snap. Most offensive schemes make adjustments based on how the defensive line and linebackers align themselves in relation to the offensive line, and what gaps they line up in. Because the center has an ideal view of the defensive forma ...

Lineman (gridiron Football)
In gridiron football, a lineman is a player who specializes in play at the line of scrimmage. The linemen of the team currently in possession of the ball are the offensive line, while linemen on the opposing team are the defensive line. A number of NFL rules specifically address restrictions and requirements for the offensive line, whose job is to help protect the quarterback from getting sacked for a loss, or worse, fumbling. The defensive line is covered by the same rules that apply to all defensive players. Linemen are usually the largest players on the field in both height and weight, since their positions usually require less running and more strength than skill positions. Offensive line The offensive line consists of the center, who is responsible for snapping the ball into play, two guards who flank the center, and two offensive tackles who flank the guards. In addition, a full offensive line may also include a tight end outside one or both of the tackles. An offensi ...

Tight End
The tight end (TE) is a position in American football, arena football, and Canadian football, on the offense. The tight end is often a hybrid position with the characteristics and roles of both an offensive lineman and a wide receiver. Like offensive linemen, they are usually lined up on the offensive line and are large enough to be effective blockers. On the other hand, unlike offensive linemen, they are eligible receivers adept enough to warrant a defense's attention when running pass patterns. Because of the hybrid nature of the position, the tight end's role in any given offense depends on the tactical preferences and philosophy of the head coach as well as overall team dynamic. In some systems, the tight end will merely act as a sixth offensive lineman, rarely going out for passes. Other systems use the tight end primarily as a receiver, frequently taking advantage of the tight end's size to create mismatches in the defensive secondary. Many coaches will often have one t ...

Penalty (American Football)
In gridiron football, a penalty is a sanction assessed against a team for a violation of the rules, called a foul. Officials initially signal penalties by tossing a bright yellow colored penalty flag onto the field toward or at the spot of a foul. Many penalties result in moving the football toward the offending team's end zone, usually either 5, 10, or 15 yards, depending on the penalty. Most penalties against the defensive team also result in the offense receiving an automatic first down, while a few penalties against the offensive team cause them to automatically lose a down. In some cases, depending on the spot of the foul, the ball is moved half the distance to the goal line rather than the usual number of yards, or the defense scores an automatic safety. Rationale Because football is a high-contact sport requiring a balance between offense and defense, many rules exist that regulate equality, safety, contact, and actions of players on each team. It is very difficult to ...

Fullback (gridiron Football)
A fullback (FB) is a position in the offensive backfield in gridiron football, and is one of the two running back positions along with the halfback. Fullbacks are typically larger than halfbacks and in most offensive schemes the fullback's duties are split among power running, pass catching, and blocking for both the quarterback and the other running back. Many great runners in the history of American football have been fullbacks, including Jim Brown, Marion Motley, Bronko Nagurski, Jim Taylor, Franco Harris, Larry Csonka, John Riggins, Christian Okoye, and Levi Jackson. However, many of these runners would retroactively be labeled as halfbacks, due to their position as the primary ball carrier; they were primarily listed as fullbacks due to their size and did not often perform the run-blocking duties expected of modern fullbacks. Examples of players who have excelled at the hybrid running–blocking–pass-catching role include Vonta Leach, Mike Alstott, William Henderson, ...
