Considering their club also cheated the salary cap, they wouldn't have much of a leg to stand on.
So after they rorted the cap by $4 million in total, they have to play the next five years with a 10 million handicap? That isn't reasonable.
I'll save you the trouble, I'm sure you could draft a suitable punishment that would have been fair but even then with the talent at their disposal Melbourne likely would have still found a way. I'm sorry they didn't just roll over and die.
Sometimes you have to listen to your mates when you're acting like a petty red-headed jilted ex.
The best revenge is massive success.
