May get shot down with this it is off season so excuse me.
The way I look at it is that once Warrington start producing and relying on the amount of talent through their own youth structure as Wigan, who have and continue to do so, you will find that a Paul Prescot situation turns up. I do hope you continue down this path as it will be good for RL. Injuries are part of the game, I would guess the more top level players you produce would lead to an higher level of names that you can mention who get injured?
Just going off Paul wood I think he had a bad run with injuries (you will know more than me) Would say four or so seasons he was at the top of his game but has tailed off since maybe not enough care?or as I think a % of players will get injured playing rugby. Morley played a lot from a young age and he was still strong three seasons back and you could say at a higher level with his NRL stint.
