Danks declared his innocence in an interview weeks ago. Its naive to think IF the Sharks go down, he won't be going with them, and he won't be trying to minimize the damage to himself. Human nature means his first reaction is to fight, but when the chances of winning any fight are done, it will be deal time.
I'm still not sure what advantage there would be if Danks 'confessed all' (assuming of course there is something to confess).
From an ASADA perspective any penalty would surely end his sports science career at a club level.
Indeed it could be argued even if he were now to be completely cleared clubs would be extremely reluctant to have anything to do with him.
Therefore mitigating any potential punishment (from say a 2 year to a six month ban) would be relatively pointless.
From a criminal law perspective I would have thought any confessions would be some way off.
Hypothetically for example if an individual administered certain substances (without a valid prescription) then he may be in trouble or if an individual administered certain substances and told the recipient he was receiving a different substance, then again there may be legal consequences.
But at this stage even if the Sharks went down I'm not sure it would be advantageous for Danks to step forward and tell all (again assuming there is anything untoward to tell).
