Pythagorean Expectation
Pythagorean expectation is a sports analytics formula devised by Bill James to estimate the percentage of games a baseball team "should" have won based on the number of runs they scored and allowed. Comparing a team's actual and Pythagorean winning percentage can be used to make predictions and evaluate which teams are over-performing and under-performing. The name comes from the formula's resemblance to the Pythagorean theorem. The basic formula is: :\mathrm = \frac = \frac where Win Ratio is the winning ratio generated by the formula. The expected number of wins would be the expected winning ratio multiplied by the number of games played. Empirical origin Empirically, this formula correlates fairly well with how baseball teams actually perform. However, statisticians since the invention of this formula found it to have a fairly routine error, generally about three games off. For example, the 2002 New York Yankees scored 897 runs and allowed 697 runs. According to James' o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Analytics
Sports analytics are a collection of relevant, historical, statistics that can provide a competitive advantage to a team or individual. Through the collection and analyzation of these data, sports analytics inform players, coaches and other staff in order to facilitate decision making both during and prior to sporting events. The term "sports analytics" was popularized in mainstream sports culture following the release of the 2011 film, ''Moneyball'', in which Oakland Athletics General Manager Billy Beane (played by Brad Pitt) relies heavily on the use of analytics to build a competitive team on a minimal budget. There are two key aspects of sports analytics — on-field and off-field analytics. On-field analytics deals with improving the on-field performance of teams and players, including questions such as "which player on the Red Sox contributed most to the team's offense?" or "who is the best wing player in the NBA?", etc. Off-field analytics deals with the business side of sp ...

Independence (probability Theory)
Independence is a fundamental notion in probability theory, as in statistics and the theory of stochastic processes. Two events are independent, statistically independent, or stochastically independent if, informally speaking, the occurrence of one does not affect the probability of occurrence of the other or, equivalently, does not affect the odds. Similarly, two random variables are independent if the realization of one does not affect the probability distribution of the other. When dealing with collections of more than two events, two notions of independence need to be distinguished. The events are called pairwise independent if any two events in the collection are independent of each other, while mutual independence (or collective independence) of events means, informally speaking, that each event is independent of any combination of other events in the collection. A similar notion exists for collections of random variables. Mutual independence implies pairwise independence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2000 Baltimore Ravens Season
The 2000 season was the Baltimore Ravens' fifth in the National Football League (NFL) and the second under head coach Brian Billick. The Ravens ended the season as Super Bowl XXXV Champions. The Ravens concluded their season with a 12–4 record, finishing 2nd in the AFC Central and qualifying for the playoffs as a wild card team. In the franchise's first post-season appearance, the Ravens won all three games, culminating in a trip to Tampa, Florida for Super Bowl XXXV, where they defeated the New York Giants, 34–7. The team's defense, which set a league record for fewest points allowed in a 16-game regular season with 10.3 points per game, is considered among the greatest of all time, including 4 games where they kept their opponents from scoring. Though just five seasons removed from the team's relocation from Cleveland, only three players (Matt Stover, Rob Burnett, Larry Webster) and no coaches remained from the 1995 Cleveland Browns roster and staff. The Ravens ranked # ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2004 New England Patriots Season
The 2004 season was the New England Patriots' 35th in the National Football League (NFL), their 45th overall and their fifth under head coach Bill Belichick. They finished with their second consecutive 14–2 record before advancing to and winning Super Bowl XXXIX, their third Super Bowl victory in four years, and their last until 2014. They are, as of 2022, the most recent team to repeat as NFL Champions and only the second to win 3 Super Bowls in a 4-year span (the other being the Dallas Cowboys from the 1992 to 1995 seasons). Following a Super Bowl win in 2003, the Patriots looked to improve their running game in the offseason. They replaced Antowain Smith with longtime but disgruntled Cincinnati Bengals running back Corey Dillon, who was acquired in a trade days before the 2004 NFL Draft; Dillon would rush for a career-high 1,635 yards in 2004. Winning their first six games of the season, the Patriots set the NFL record for consecutive regular season victories (18), which ...

Super Bowl
The Super Bowl is the annual final playoff game of the National Football League (NFL) to determine the league champion. It has served as the final game of every NFL season since 1966, replacing the NFL Championship Game. Since 2022, the game is played on the second Sunday in February. Prior Super Bowls were played on Sundays in early to mid-January from 1967 to 1978, late January from 1979 to 2003, and the first Sunday of February from 2004 to 2021. Winning teams are awarded the Vince Lombardi Trophy, named for the coach who won the first two Super Bowls. Due to the NFL restricting use of its "Super Bowl" trademark, it is frequently referred to as the "big game" or other generic terms by non-sponsoring corporations. The day the game is played is often referred to as "Super Bowl Sunday" or simply "Super Sunday". The game was created as part of a 1966 merger agreement between the NFL and the competing American Football League (AFL) to have their best teams compete for a champi ...

John Hollinger
John Hollinger (born May 17, 1971) is the former Vice President of Basketball Operations for the Memphis Grizzlies of the National Basketball Association (NBA) and current Senior NBA columnist at The Athletic. Prior to December 2012, he was an analyst and writer for ESPN, primarily covering the NBA. Hollinger grew up in Mahwah, New Jersey, and is a 1993 graduate of the University of Virginia. Hollinger developed the website ''Alleyoop'' in 1996, initially as a hobby and sounding board for his musings on the game. Touting the site as "The Basketball Page for Thinking Fans," Hollinger followed in the footsteps of noted analysts Dean Oliver and Bob Bellotti in a quest for the ultimate basketball statistic. During ''Alleyoops early years, Hollinger experimented with offensive and defensive ratings (points created and allowed per 100 possessions) in much the same way as Oliver, as a means of quantifying a player's overall contribution to his team. While the methods were hardly grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basketball Statistician
In basketball, a basketball statistician is an official responsible for recording statistics during games, and providing reports to coaches, league officials, and (depending on the competition) media and spectators. In organized competition and at professional level, games may have a panel of one or more statisticians in attendance. The statistician's role is to record the game and provide a report (commonly known as a boxscore) during breaks between periods, and at the completion of each game. While the game scorer keeps track of points scored and fouls committed, statisticians also record other details of the game, such as assists, turnovers, and field goal percentage. Game statistics can be recorded using tally sheets, or computer software designed for the purpose. Computerised methods are increasingly being used for professional competition and bigger tournaments.Australian Basketball Statistics Committee Manual, July 2007 Notable Basketball statisticians * John Hollinger ...
