I can't understand why people on, maybe not this forum,keep saying guys like Quinnlan,Cummings,Ryan & Shannon Crook are only 18-20 years old & probably a couple of yesr away from 1st Grade.A fairly astute football judge by the name of Peter Sterling has always said "if you're good enough,you're old enough".Have a look back over the years & see how many players made their debut whilst still in their teens.Is there any difference between young blokes making mistakes(that they will learn from)to that of old blokes making mistakes(from which they wont learn from).
