The NRL have handle this with distinction. They have maintained an arms length and allowed ASAD to run their investigation into the players, while the NRL ran their own separate investigation into the club and medical staff.
When ASADA hand down their penalties against the players, and there will be penalties, that's when the NRL's duty of care begins as they will have to manage the players through that process. Not while the invesitagation is still taking place.
Read Diablo's post above about the debacle the AFL caused trying to meddle in the process and influence the outcome. There were back room deals and under the table agreements, threats of legal action, counter threats, it was a complete shambles.
The NRL have handled this professionally. If that upsets Gallen, too bad.
Chook.
