If ASADA find good evidence that that he had knowledge I would suggest that a ban would be considerably more than 2 years. Subject to evidence Elkin and Flanno should be banned for life.
On the legal front, some players may sue. I think it probably depends on their personal makeup and their regard for the club.
Our club is not a big multinational business, it is an organisation that is made up of us, the fans, and I would like to think that the players recognise that.
If I was a player, I would go after the perpetrators not the club. Especially as it appears that the whole sorry saga was (is) a comedy of slapstick-like ineptness, with no real calculated intent.
Then again I've loved the place for nearly 40 years.....you don't sue family.
