I do not know of any person who has gone to prison for breaking a sports contract. That is one of the most ridiculous things I have ever heard of. he could come back to Australia whenever he wanted with no fear of imprisonment. I would go as far as to sue the Dogs and the NRL for loss of income if their actions cause it. His is capable of earning at least 1.5 million a year just on match payments.
Sure, SBW could play out his remaining 4 years with the Dogs and receive his 450k as promised, but I would take to court anybody who restricted me from earning triple that. In other words, match the contract I am being offered now and I will play. Force me to sit it out and I will sue for loss of income that is anything over the original 450k contract. There is nothing fairer than that and to argue otherwise is to argue against somebodies right to earn what he and others believe he is worth.
