Sports are slow to adapt other codes.
League started the adaptation by brining in Union goal kickers to coach League Kickers.
Union adapted people like SBW and offloading....before that they adapted some of the Storm systems....and before that they hired League defensive coaches for NZ Union teams, the England team and so forth.
AFL would have lots of transferable skills.
AB's also had an ex AFL guy as a skills Coach, his name was Byrne, now with the Wallabies I believe.
