Guys, guys, the best thing you could do to hurt 'The Spew' would be to do something to damage the strength of the AFL, not necessarily one of the clubs (although I do see the irony in having the fat turd fine his old club

).
If you were mega rich you could do a Kerry Packer and start your own 'super-league'. If the clubs started to split from the league then they would make the spew irrelevant and put him down in history as the guy in charge when the current league dissolved!!!
If that was too big, how about running your own 'Challenge Cup' competition. Kind of like the NAB Cup but a private venture with massive $$$ on offer to the winners. Clubs could be invited to join but no group deal with the AFL. Some clubs somewhere would join up and imagine seeing some amateur club walk away with $15m in prizemoney etc. The next year all of the AFL clubs would be rushing away from any collective AFL agreement to sign up for the comp. It would be awesome to see the turmoil it created as clubs fought with the AFL to either remain united and face the threat, or be the 1st club to break away and take the $$$. I dont mean a competition to challenge the AFL, just an alternative NAB cup kind of thing.
The AFL would want to sanction, approve and collectively bargain with you as the competition sponsor or provider. You say:
"get stuffed, if the clubs want to enter into my comp they can deal directly with me".
Clubs could still be part of the AFL but be forced to make an individual deal with you for the one pre-season competition. Eventually they go back to the AFL. Imagine the divisiveness and bickering that the Spew would have to contend with amongst the clubs!! The fallout would be better than the games!!! he'd be trying to keep them together to face the threat united, they'd all be out individually for the money!! Spew would be tap dancing faster than Gene Kelly trying to stop the whole lot imploding!!
