I think Paul Roos basically agrees with you Hypen and he has been a long term advocate of simply raising the age by either one or two years.
It wouldnt stop everyone getting injured but would allow young athletes, many of whom are actually still growing to finish up and have a chance at it. Griffen Logue I think originally did a growth plate in his foot.
I could live with seeing Brayshaw, Logue, Cerra etc do an extra year at Peel.
Some of these guys dont even play in the seniors at WAFL level, they basically come straight in. I think Logue only played 12 or 18 league games!
