I played as----
----'Left Prop' for my 'House' (Ebor) team when I was at AHGS, (Archbishop Holgate Grammar School), in York.
That was when a scrum had the scrum-half put the ball between the two opposing front-rows with the 'hookers', (small lads who were held with their boots barely touching the ground so they could reach-out with their boots and try 'hook' the ball backward to the Second Row who, in turn, 'hooked' it back for the scrum-half to retrieve and either 'kick-for-touch' or pass it to the line of 'Forwards').
The modern game, for reasons unknown, has the scrum-half 'insert' the ball directly into the Second Row which, to my mind, negates the whole idea of 'scrums'.
I much prefer League as a spectator sport. Phil
