of ancient Thai numbers, making identification by opposing teams virtually impossible. Will Greenwood, who normally played at inside centre, preferred to wear the number 13 shirt rather than the usual number 12 assigned to this position for superstitious reasons. During the 2003 Rugby World Cup Final he played inside centre wearing number 13 and Mike Tindall played outside him in the number 12 shirt. Diocesan College, the first school to play rugby in South Africa, has always played without numbers to emphasise that team aspect of the sport. Other South African schools such as Pietermartizburg College in Kwa Zulu Natal province adopted the same approach until recent years when they decided to use player identification numbers likely due to television coverage of matches and referees and officials needing to cite players by number.
