 Rob Valentine played right-, i.e.number 12, and scored a try in Wakefield Trinity's 11-22 defeat by Halifax in the 1971–72 Player's No.6 Trophy Final during the 1971–72 season at Odsal Stadium, Bradford on Saturday 22 January 1972.Rob Valentine transferred from Hawick RFC to Huddersfield in 1963 for a signing-on fee of £4,000 (based on increases in average earnings, this would be approximately £160,800 in 2016), he made his début for Wakefield Trinity during October 1970, 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.
