Information:  - Canadian football is a form of gridiron football played in Canada in which two teams of 12 players each compete for territorial control of a field of play long and wide attempting to advance a pointed prolate spheroid ball into the opposing team's scoring area (end zone).  - Marcus Harris ( born October 11 , 1974 ) is a former American college football player who was an All - American wide receiver who played for the University of Wyoming and won the Fred Biletnikoff Award as the best college wide receiver in the nation .  - Frederick S. Biletnikoff (born February 23, 1943) is a former gridiron football player and coach. He was a wide receiver for the Oakland Raiders in the American Football League (AFL) and National Football League (NFL) for fourteen seasons and later an assistant coach with the team. He retired as an NFL player after the 1978 season, and then played one additional season in the Canadian Football League (CFL) for the Montreal Alouettes in 1980. While he lacked the breakaway speed for deep pass receptions, Biletnikoff was one of the most sure-handed and consistent receivers of his day. He was also known for running smooth, precise pass routes. He is a member of both the Pro Football Hall of Fame and College Football Hall of Fame.  - Florida State University (commonly referred to as Florida State or FSU) is an American public space-grant and sea-grant research university. Its primary campus is located on a 1,391.54-acre (5.631 km2) campus in Tallahassee, Florida, United States. It is a senior member of the State University System of Florida. Founded in 1851, it is located on the oldest continuous site of higher education in the state of Florida.  - The Fred Biletnikoff Award is presented annually to the outstanding receiver in American college football by the Tallahassee Quarterback Club Foundation, Inc. (TQCF), an independent not-for-profit organization which created the award in 1994 and has sponsored it since. The award is named for Fred Biletnikoff, who played college football at Florida State University and professionally with the Oakland Raiders. Any NCAA Division I FBS player who catches the football through the forward pass is eligible to be selected as the award winner, although every winner since 1994 has been a wide receiver. A national selection committee consisting of over 540 journalists, commentators, broadcasters, and former players selects the award winner. No member of the board of trustees of the foundation has a vote.  - History. Even after the emergence of the professional National Football League (NFL), college football remained extremely popular throughout the U.S.  Although the college game has a much larger margin for talent than its pro counterpart, the sheer number of fans following major colleges provides a financial equalizer for the game, with Division I programs  the highest level  playing in huge stadiums, six of which have seating capacity exceeding 100,000. In many cases, college stadiums employ bench-style seating, as opposed to individual seats with backs and arm rests. This allows them to seat more fans in a given amount of space than the typical professional stadium, which tends to have more features and comforts for fans. (Only two stadiums owned by U.S. colleges or universities  Papa John's Cardinal Stadium at the University of Louisville and FAU Stadium at Florida Atlantic University  consist entirely of chairback seating.)  - A wide receiver (also referred to as wideouts or simply receivers) is an offensive position in American and Canadian football, and is the key player in most of the passing plays. They get their name because they are split out "wide" (near the sidelines), furthest away from the rest of the team. Wide receivers are among the fastest players on the field. The wide receiver functions as the pass-catching specialist.  - The Oakland Raiders are a professional American football franchise based in Oakland, California. The team commenced operations in 1960 as a member of the American Football League (AFL); they are currently members of the National Football League (NFL), which merged with the AFL in 1970.
