Gary Cooper made his début for Featherstone Rovers on Wednesday 20 August 1958, he appears to have scored no drop-goals (or field-goals as they are currently known in Australasia), but prior to the 1974–75 season all goals, whether; conversions, penalties, or drop-goals, scored 2-points, consequently prior to this date drop-goals were often not explicitly documented, therefore '0' drop-goals may indicate drop-goals not recorded, rather than no drop-goals scored.
