Aside from Sterling whom I think is the stand out talent wise by far we've being a bit sparse for top top scrums halves.
Billy Anderson 216 games, 16 tries.
At only 5ft 6 and 11 stone he was considered to be a hard, wily bundle of energy, your typical 'old fashioned' scrum half.
Took us to 4, yes that's right 4 CC finals, 1907/08, 08/09, 09/10 (all losing) and then finally winning the big one in 1913/14. Missed out on rep honours despite shining in the trials for the 1910 tour down under. Playing 6 seasons over two stints with us & a couple of seasons at Batly he had just one game after the war.
Eddie Caswell, 401 app, 98 tries, 5 goals. One of the very few in the '400' club. Formed a great partnership with Stan Whittey in the 20s as well as playing off half for a fair few of his games.
he was another robust, speedy and crafty half that helped the great 2nd rower Bob Taylor to run in plenty of his tries as well as amass almost a century for himself. Missed out on international duty due to the likes of the great Jonty Parkin but rep'd for Wales 3 times. Won the championship in 20/21, Yorkshire Cup in 23/24 along with 2 CC final losses and 2 yorks cup final losses.
Tommy Finn, 375 apps, 132 tries, 1 goal. Originally spending 4 seasons at St.Helens with only 8 appearances his 11 seasons co-incided with one of Hull's greatest ever periods from the mid 50s to the mid 60s. Though not considered a 'great' he formed a brilliant partnership with JW and worked his magic especially down the blind side and ensured our 'Panzer' pack did its job. A prolific try scorer & brilliant support player scored the vital winning try in the 1956 championship final at Maine Rd and our only try in the defeat by Wigan in the '59 CC final. No rep honours but won 2 Championship medals and 1 losers, 2 losing CC medals and 2 losing Yorkshire cup medals
Honourable mentions to Chris Davidson and Kenny Foulkes, two top club men.
