In the interests of kooky theories during byes, I've got one for the over the top interchange situation.

He's done it with everything else, so I'm going to assume Mick Malthouse will take interchange rotations to a ridiculous level and force the hand of the AFL into making a rule change.

The players have to wear on their boot (or somewhere else if that's going to be a problem with kicking) that the ponces who belong to tennis clubs have on the laces of their sneakers which has in it the same thing that is in the train/bus smart rider thing.

For a player to run on or off, he has to swipe his foot past an interchange station. If a player goes onto the ground without a player going off, a big red light flashes so everyone at the ground can see it. Stopping the Swans from cheating.

It would also mean you could control things like, the number of interchanges made in a quarter.

Personally, if they were going to have rules, I'd like to see a maximum interchange for each player rather than the whole team. So each player could come off maybe 5 times in a match.

If you're not sold, down the track it could also be used to administer electric shocks to players crossing the line when they're not supposed to and, for those South Fremantle performance based types, you could pay the player by the minute they are on the ground.
