Have heard a few whispers that with the ever changing league that is the VFL, with the changes for 2008 some of the clubs have some pretty big cheque books and are offering big bucks enticing ex-VFL types to go home again, more then they are getting from the SANFL.
Obviously makes it harder to recruit new players as well.
Also did hear of another SANFL (ex VFL) player who did not want to go back to his old VFL team as the clubs keep changing so much over there (with the AFL teams sticking their noses in all the time) he didnt know anyone at the club from only a few years ago.
