SackSEER
SackSEER is a statistical model for predicting the performance of collegiate American football players who are trying to play in the National Football League. SackSEER was developed in 2010 by Nate Forster of Football Outsiders. SackSEER only applies to defensive ends who are "edge rushers". The first version of SackSEER was published in the 2010 Football Outsiders Almanac.{{cite web , url = https://www.footballoutsiders.com/nfl-draft/2010/introducing-sackseer , archive-url = https://web.archive.org/web/20120107130952/http://www.footballoutsiders.com/nfl-draft/2010/introducing-sackseer , url-status = dead , archive-date = January 7, 2012 , publisher = footballoutsiders.com , title = Introducing SackSEER , date = 2010-04-10 , last = Forster , first = Nate , accessdate = 2018-12-18 Methodology According to the SackSEER chapter in the 2010 Football Outsiders Almanac, the formula considers four factors: * vertical leap *short shuttle time *SRAM (an adjusted measure of p ...

Statistical Model
A statistical model is a mathematical model that embodies a set of statistical assumptions concerning the generation of Sample (statistics), sample data (and similar data from a larger Statistical population, population). A statistical model represents, often in considerably idealized form, the Data generating process, data-generating process. When referring specifically to probability, probabilities, the corresponding term is probabilistic model. All Statistical hypothesis testing, statistical hypothesis tests and all Estimator, statistical estimators are derived via statistical models. More generally, statistical models are part of the foundation of statistical inference. A statistical model is usually specified as a mathematical relationship between one or more random variables and other non-random variables. As such, a statistical model is "a formal representation of a theory" (Herman J. Adèr, Herman Adèr quoting Kenneth A. Bollen, Kenneth Bollen). Introduction Informally, a ...

American Football
American football, referred to simply as football in the United States and Canada and also known as gridiron football, is a team sport played by two teams of eleven players on a rectangular American football field, field with goalposts at each end.

The offense must advance the ball at least ten yard, yards in four Down (gridiron football), downs or plays; if they fail, they turnover on downs, turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the Glossary of American football#drive, drive.

National Football League
The National Football League (NFL) is a Professional gridiron football, professional American football league in the United States. Composed of 32 teams, it is divided equally between the American Football Conference (AFC) and the National Football Conference (NFC).

Football Outsiders
Football Outsiders (FO) was a website started in July 2003 which focused on advanced statistical analysis of the National Football League (NFL). The site was run by a staff of regular writers, who produced a series of weekly columns using both the site's in-house statistics and their personal analyses of NFL games. In 2005 and 2006, the site partnered with FOXSports.com to cross-publish many of the Outsiders' regular features, including power rankings based on a "weighted" version of the DVOA (Defense-adjusted Value Over Average) statistic. In 2007, Football Outsiders content appeared on FOXSports.com (in a reduced capacity) along with AOL Sports and ESPN.com. Since 2008, the site has partnered exclusively with ESPN and provides mostly ESPN Insider content. In 2009, Football Outsiders began analyzing college football using similar statistical principles. As of 2023, after financial mismanagement, the site seems to have been abandoned by its owners. As of September 1, 2023, th ...

Defensive Ends
Defensive end (DE) is a defensive position in the sport of gridiron football. This position has designated the players at each end of the defensive line, but changes in formations over the years have substantially changed how the position is played. History Early formations, with six- and seven-man lines, used the end as a containment player, whose job was first to prevent an " end run" around his position, then secondarily to force plays inside. When most teams adopted a five-man line, two different styles of end play developed: "crashing" ends, who rushed into the backfield to disrupt plays, and "stand-up" or "waiting" ends, who played the more traditional containment style. Some teams would use both styles of end play, depending on game situations. Traditionally, defensive ends are in a three-point stance, with their free hand cocked back ready to "punch" an offensive lineman, or in a two-point stance like a strong safety so they can keep containment. Some defensive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Leap
A vertical jump or vertical leap is the act of jumping upwards into the air. It can be an exercise for building both endurance and strength, and is also a standard test for measuring athletic performance. It may also be referred to as a ''Sargent jump'', named for Dudley Allen Sargent. Types The vertical jump is divided into two different types: * Standing vertical jump: This refers to a vertical jump done from a standstill with no steps being involved at all. It is usually preceded by a quick crouching action. * Running vertical jump: This refers to a vertical jump after a run up: the last step of the run is used to launch into the jump. This may help to add additional energy to the jump and improve on the standing vertical jump result. In general, the standing vertical jump is the one that is used as an official measurement for athletes. Usage Vertical jump measurements are used primarily to measure athletic performance. In sports such as high jump, netball, basketball, Austra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarterback Sack
In gridiron football, a sack occurs when the quarterback (or another offensive player acting as a passer) is tackle (football move), tackled behind the line of scrimmage before throwing a forward pass, when the quarterback is tackled behind the line of scrimmage in the "passing pocket, pocket" and without clear intent, or when a passer runs out of bounds behind the line of scrimmage due to defensive pressure. This often occurs if the opposing team's defensive team, defensive line, linebackers or defensive backs are able to apply pass pressure (also called a pass rush) to quickly get past blocking (American football), blocking players of the offensive team (the quarterback's protection), or if the quarterback is unable to find an available eligible receiver (including wide receivers, running backs and tight ends) to catch the ball, allowing the defense a longer opportunity to tackle the quarterback. A sack is advantageous for the defending team as the offense loses a Down (gridiro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NFL Draft
The NFL draft, officially known as the Annual Player Selection Meeting, is an annual event which serves as the most common source of player recruitment in the National Football League. Each team is given a position in the drafting order in reverse order relative to its record in the previous year, which means that the team with the worst record is positioned first and the Super Bowl champion is last. For teams that had the same record, their position in the draft order for each round rotates in some way amongst the teams with tied records. From this position, the team can either select a player or trade its position to another team for other draft positions, a player, or players, or any combination thereof. The round is complete when each team has either selected a player or traded its position in the draft (sports), draft. The first draft was held in 1936 NFL draft, 1936 and has been held every year since. Certain aspects of the draft, including team positioning and the number ...
