Your whole argument rests on the unspoken assertion that the only standard by which the reasonableness of actions can be judged is whether they conform to the rules. Of course he's conforming with the rules. Of course the AFL can't compel him to take a medical examination. Of course there are reasons why it is undesireable that the AFL be able to compel him, even if they wanted to. None of this changes the fact that the way he's acting is designed to affect the outcome of the draft.
Some people would consider that unreasonable (NOT against the rules). I'm not necessarily one of those people. I just find it ridiculous the way you're trying rebut any criticisms by the self-evident fact that he's not breaking any rules.
he isn't breaking any rules. His manager has told him what to do. This would be the same if you got a lawyer to represent you in a murder case or divorce for example. He is being guided. He would have said "What do I have to do to get to Collingwood". His manager said "Do nothing and speak to no one, go into hiding". Ball is not at fault. He want what he wants like we want a new TV. We will still settle for the old one. Rules are rules. People will always try and push them.
