Totally don't understand the fascination with Craig and head of sports science. Sports science is exactly that, a science, which means nothing is accepted until it is researched and published in a peer reviewed journal. There aren't many secrets in the sports science world.
In addition, experience means very little. What they were doing 10 years ago is ancient history, much of Craigs experience is completely irrelevant now. The science has changed and the game has changed. Best thing you can hope for is a head of sports science who can spot good young talent in the crop of PHD and Masters candidates that are lining up to join the sports science departments of AFL clubs these days.
It's these kids who are most on top of all the latest research in the field, not necessarily the crusty old farts who have been doing it for 30 years.
