In sports, a coach is a person involved in the direction, instruction and training of the operations of a sports team or of individual sportspeople. Also a sport teacher.

A coach, particularly in a major operation, is traditionally supported by one or more assistant coaches. The staff may include coordinators, strength and fitness specialists, and trainers.

In football, the duties of a coach can vary depending on the level they are coaching at and the country they are coaching in, amongst others. In youth football, the primary objective of a coach is to aid players in the development of their technical skills, with emphasis on the enjoyment and fair play of the game rather than physical or tactical development. In recent decades, efforts have been made by governing bodies in various countries to overhaul their coaching structures at youth level with the aim of encouraging coaches to put player development and enjoyment ahead of winning matches.

In professional football, the role of the coach or trainer is limited to the training and development of a club's "first team" in most countries. The coach is aided by a number of assistant coaches, one of which carries the responsibility for the training and preparation of the goalkeepers. The coach is also assisted by medical staff and athletic preparators.

Sport (or, in the United States, sports) is all forms of competitive physical activity which, through casual or organised participation, aim to use, maintain or improve physical fitness and provide entertainment to participants. Hundreds of sports exist, from those requiring only two participants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals.

Sport is generally recognised as activities which are based in physical athleticism or physical dexterity, with the largest major competitions such as the Olympic Games admitting only sports meeting this definition, and other organisations such as the Council of Europe using definitions precluding activities without a physical element from classification as sports. However, a number of competitive, but non-physical, activities claim recognition as mind sports. The International Olympic Committee (through ARISF) recognises both chess and bridge as bona fide sports, and SportAccord, the international sports federation association, recognises five non-physical sports, although limits the amount of mind games which can be admitted as sports.

Patrick George Duffy (born March 17, 1949) is an American character actor of stage and film. He is best known for his role on the CBS television drama Dallas, where he played Bobby Ewing from 1978 to 1985 and from 1986 to 1991. Duffy will return to reprise his role as Bobby in a new up-to-date Dallas currently scheduled to air its 10-episode first season in Summer 2012. He is also well known for his role on the ABC television sitcom Step by Step as Frank Lambert, the husband of Carol Lambert, played by Suzanne Somers, from 1991 to 1998.

In 1976, Duffy landed the role of Mark Harris in the short-lived television series Man from Atlantis. Following the series' cancellation in early 1978, he got his big break in the role of Bobby Ewing on the TV series Dallas. The show became a worldwide phenomenon, ranking in the top 3 for the first half of the 1980s. Despite its success, Duffy opted to leave the series in 1985 with his character being killed off onscreen. However, with both the show and his career on the decline, he returned in 1986 in the infamous shower scene that rendered the entire 1985–1986 season "just a dream". Duffy then remained with the series until its cancellation in 1991. He also appeared in several episodes of the spin-off series Knots Landing between 1979-82. Throughout the 13-year run of Dallas, Duffy directed several episodes of the series. In 1992, he began a role of the public announcing host and Pete's rival, Harold Hatchback (which is from Rob Paulsen's voice role) in the episode, "Buddy Building" from Goof Troop.
