For eight seasons from 1959 to 1966, Motley captained the then dominating team of the SANFL, Port Adelaide, including a stint as captain-coach from 1959 to 1961. He was the only man to appear in all nine of the Magpies' premiership teams between 1954 and 1965. Motley played a total of 258 games for Port between 1953 and 1966 and also represented South Australia on 28 occasions.[4]
During his career, Motley was never dropped from the team, nor was he reported. In this era, not being reported for foul play was a rarity for a player as having a certain amount of mongrel or thuggery was seen as commonplace.[3]
Motley was named Port Adelaide's best and fairest player in 1958, 1959, 1963, and 1965; and won the Magarey Medal in 1964.[5]
North Adelaide coach (1967–1969)
Following his playing retirement, Motley went on to coach North Adelaide from 1967 to 1969, taking the club to third, third, and fifth place respectively. The Roosters won the minor premiership in 1967 but were unable to compete successfully against Sturt and Port Adelaide in the major round. Under Motley's tutelage, Australian Football Hall of Fame Legend Barrie Robran debuted and won his first Magarey Medal.
Honours
After retiring, Motley was bestowed with several honours including life membership of Port Adelaide and the SANFL, and membership of the South Australian Football Hall of Fame and the Australian Football Hall of Fame. In 2001, Motley was named on a half-back flank in Port Adelaide's 'Greatest Team of All Time'.[3]
