The NBL and their salary cap
A hint from someone in the know on OzHoops (I read it, to save you the time™) suggests that the NBL might start to take a closer (likely token, but at least it's something) look at teams' treatment of the league salary cap.
Sounded like anything up to $1.2m was a safe assumption for some clubs, but go over that and you're inviting trouble.
Why has it taken until now?
As someone rightfully commented on the OzHo boards, the NBL can approve all sorts of incorrect contracts (less than the player is getting paid) while half of the clued-in types of forums can list specific prices that are very likely accurate. The NBL don't even need to police it all, just take a closer look at the blatant cases and do a bit of research into the rumours.
