What if he said he was desperately homesick (for Tassie/ Gold Coast/ Melbourne), that a family reunion (especially to play alongside his brother, just like Scott Selwood) was something he desired, that he didn't really like living in Freo? Then wouldn't he have a similar argument to McCarthy?
Here's a good opportunity for that 'reversal of attitudes' in the media that others have referred to before about McCarthy, ie we'd be nasty not to free him up, whereas GWS is quite within their rights to keep Cammac.
I sense we'd be saying - he loves Freo and the Club, he's a required player, and whatever else Leon Cameron suggests we say!
Overall, however, I agree with those who say let's put him up if it means we get McCarthy for pick 14 and next year's first round pick. Otherwise, let's be just like GWS.
