Nasser and Cooper have been way out ahead of the ARU, shaping this story in their interest from the start. Even this story today- note the author is a league journo. If it came from the ARU why would they give it to Brad Walter?
This was always going to be the case. The two sides are playing by completely different rules.
It would be completely unprofessional for the ARU to publically release the details of private contracts. The best they can do is refute the claims made by Cooper and Nasser but only in a general way that doesn't involve the release of specifics.
