Sir Gareth Owen Edwards CBE is a Welsh former rugby union player who played scrum-half and has been described by the BBC as "arguably the greatest player ever to don a Welsh jersey".

In the game of rugby union, there are 15 players on each team, comprising eight forwards and seven backs. In addition, there may be up to eight replacement players "on the bench", numbered 16–23. Players are not restricted to a single position, although they generally specialise in just one or two that suit their skills and body types. Players that play multiple positions are called "utility players".
