what does tight end position in football do
Tight end 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. 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 tight end who specializes in blocking in running situations while using a tight end with better pass-catching skills in obvious passing situations.
Quarterback In modern American football, the quarterback is usually the leader of the offense. The quarterback touches the ball on almost every offensive play, and his successes and failures can have a significant impact on the fortunes of his team. Accordingly, the quarterback is among the most glorified and scrutinized positions in team sports.[1] Prior to each play, the quarterback will usually tell the rest of his team which play the team will run. After the team is lined up, the center will pass the ball back to the quarterback (a process called the snap). Usually on a running play, the quarterback will then hand or pitch the ball backwards to a half back or full back. On a passing play, the quarterback is almost always the player responsible for trying to throw the ball downfield to an eligible receiver downfield.[2] Additionally, the quarterback will often run with the ball himself, which could be part of a designed play like the option run[3] or quarterback sneak,[4] or it could be an effort to avoid being sacked by the defense.[5]
American football Football games last for a total of 60 minutes in professional and college play and are divided into two-halves of 30 minutes and four-quarters of 15 minutes.[71][72] High school football games are 48 minutes in length with two-halves of 24 minutes and four-quarters of 12 minutes.[73] The two-halves are separated by a halftime period, and the first and third quarters are also followed by a short break.[71][72][74] Prior to the start of the game, the referee and team captains for each team meet at midfield for a coin toss. The visiting team is allowed to call 'heads' or 'tails'; the winner of the toss is allowed to decide between choosing whether to receive or kick off the ball or choosing which goal they want to defend, but they can also defer their choice until the second half. The losing team, unless the winning team decides to defer, is allowed to choose the option the winning team did not select, and receives the option to receive, kick, or select a goal to defend to begin the second half. Most teams choose to receive or defer, because choosing to kick the ball to start the game would allow the other team to choose which goal to defend.[75] Teams switch goals following the first and third quarters.[76] If a down is in progress when a quarter ends, play continues until the down is completed.[77][78][79]
National Football League Draft Players who have been out of high school for at least three years are eligible for the NFL draft. The rules do not state that a player must attend college, but virtually all of the players selected in the NFL draft have played college football, usually in the United States but occasionally from Canadian universities as well. A few players are occasionally selected from other football leagues like the Arena Football League (AFL), the Canadian Football League (CFL), and the German Football League (GFL). A small handful of players have also been drafted from colleges who played other sports than football.
