The Walter Camp Player of the Year Award is given annually to the collegiate American football player of the year, as decided by a group of National Collegiate Athletic Association Division I FBS head coaches and sports information directors under the auspices of the Walter Camp Football Foundation; the award is named for Walter Camp, an important and influential figure in the development of the sport.
 Three players have won the award twice: Colt McCoy of the University of Texas in 2008 and 2009, Archie Griffin of Ohio State in 1974 and 1975, and O. J. Simpson of USC in 1967 and 1968.
Coleman Roberts Griffith (May 22, 1893 – February 1966) was an American sport psychologist.
 Born in Iowa, he is considered the founder of American sport psychology.
 Griffith studied at Greenville College until 1915, and then studied psychology at the University of Illinois.
 While at the University of Illinois, Griffith established what he claimed to be the first sports psychology laboratory in the United States.
 At this time Griffith worked closely with the University of Illinois football team, studying how factors such as psychomotor skills and personality variables related to performance and learning of athletic skills.
 Due to financial reasons, the Research in Athletics Laboratory eventually was closed, which led to Griffith becoming a sport psychologist with the Chicago Cubs baseball team.
 Throughout his time with the Chicago Cubs, Griffith examined the players and completed a series of reports for Philip K. Wrigley, the owner of the Chicago Cubs team, with the results eventually summarized in a large report.
 His ideas were met with resistance, but he helped the Cubs to be successful while there.
 Griffith ended his career in the department of education at the University of Illinois until his retirement in 1961.
 Some of Griffith's main contributions to the field of sports psychology came from his publications "The Psychology of Coaching" (1926) and "The Psychology of Athletics" (1928).
 These publications were written during Griffith’s time at the University of Illinois and covered topics such as how a coach must have knowledge in athletics, physiology, and psychology to be successful.
 Much of Griffith's research and publications have become the foundation for the widely growing field of sports psychology and many of his ideas are still used today.
The 1916 Florida Gators football team represented the University of Florida in the sport of American football during the 1916 college football season.
 The season was C. J. McCoy's third and last as the head coach of the Florida Gators football team.
 Depleted of first-string football talent and lacking depth, McCoy's 1916 Florida Gators ended their season disastrously with an overall record of 0–5 and a Southern Intercollegiate Athletic Association (SIAA) conference record of 0–4.
Colt's Manufacturing Company (CMC, formerly Colt's Patent Firearms Manufacturing Company) is an American firearms manufacturer, founded in 1855 by Samuel Colt.
 It is the successor corporation to Colt's earlier firearms-making efforts, which started in 1836.
 Colt is known for the engineering, production, and marketing of firearms, most especially between the 1850s and World War I, when it was a dominating force in its industry and a seminal influence on manufacturing technology.
 Colt's earliest designs played a major role in the popularization of the revolver and the shift away from earlier single-shot pistols.
 Although Samuel Colt did not invent the revolver concept, his designs resulted in the first very successful ones.
David Neill (born July 17, 1980) was an American college football quarterback for the University of Nevada from 1998 to 2001.
 In 1998, he set an NCAA record for most touchdown passes in a season by a freshman with 29 thrown.
 This record was tied in 2006 by Colt McCoy of the Texas Longhorns, and broken the following season by Sam Bradford of Oklahoma.
 Neill also previously held the school record for most completed passes with 763.
 This has since been broken by Cody Fajardo (878).
 He received attention from the Jacksonville Jaguars and New York Jets of the NFL, but he opted for a veterinary career and left football prior to the 2002 NFL Draft.
Beast (Henry Philip "Hank" McCoy) is a fictional superhero appearing in American comic books published by Marvel Comics.
 The Marvel Universe features an undisclosed number of alternate realities in what they describe as the Multiverse, with several of those worlds featuring an alternate version of Hank McCoy.
 McCoy is often referred to as "Beast" in those alternate realities, although it is not always the case.
 His appearance in the various universe varies from appearing like a normal human being to various feral forms of the blue furred "Beast" version.
Casey Burl "Case" McCoy (born February 12, 1990) is a former American football quarterback for the University of Texas Longhorns football team.
 He started 16 games for Texas over a three-year period, amassing a 9–7 record.
 He is also known as the younger brother of NFL quarterback Colt McCoy.
Greg McCoy (born September 8, 1988) is a former American football cornerback.
 He was drafted by the Chicago Bears in the seventh round of the 2012 NFL Draft.

Australian football was one of two demonstration sports at the 1956 Summer Olympics held in Melbourne, Australia.
 The rules stated that the hosts must organize both a native game and a sport foreign to the organizing country as "demonstration sports".
 Australian rules football was chosen as the "native" sport; and baseball, an American sport, was chosen as the "foreign" sport.
Daniel "Colt" McCoy (born September 5, 1986) is an American football quarterback for the Washington Redskins of the National Football League (NFL).
