You may be right, but maybe not.
Missing the Nab cup, does that mean all of the regional games as well if they lose the first Nab cup game? If it doesn't it could be a one nab cup game penalty. Next, training with the Bullants is a penalty, but they are still training under club supervision just losing the interaction with their mates. If it happened during the year it would be a suspension from real games. It sounds a bit like the Michael Long penalty on Simmonds when he nearly killed him and ended up missing a couple of of pre season games. It wasn't a penalty. That was a disgrace. This may also, even though club enforced, be the same type of penalty.
The fact that the Casboult issuse has not been publicly addressed to me means the AFL will want to step in. The media ( non footy media ) ( public ) won't let this go without some action from the AFL. This is a big issue, don't take it lightly. If the AFL makes no comment as to the solution they will stand condemned. The AFL has a duty to each young recruit and their family to ensure a safe working environment within reasonable limits and will need to be pro-active on this matter. The last thing it will need is government interference.
