John Service "Jack" Strong made his debut with one game as a 17-year-old in 1901 before returning to his school side in 1902 and standing out of VFL football for a year. The season he was the captain of the Grammar cricket side, and of the school itself.
A rover, Strong played his only full season in 1904 and never appeared in more than 13 games in more than 10 years associated with the club. He missed the first 10 games of 1905 due to pleurisy. His 1908 season was hampered by having to work on Saturdays, improving his output from five games to 13 when the shop began closing on the weekends in 1909.
In the 1910 pre-season he was linked to Brighton, but returned for three games with Melbourne. In Round 8, 1912 he returned to the side for his first game since 1910 and would go on to play six games before the end of the season.
He also played first class cricket for the University club.
After his football career ended strong moved into business, serving amongst other appointments as Chief Assistant British Trade Commisioner in Melbourne and Sydney between 1916 and 1925. He was also a director of the Austin Motor Company.
