I think you and Ink are making a big assumption that Robbie has not been financially disadvantaged.
As I replied to Ink on the page above, if Robbie's contract payments include an amount for interest on deferred payments, then he will suffer no financial disadvantage over the life of the contract.
If, however, no component of interest is included in his contract payments then he will have suffered a financial penalty for agreeing to defer the amounts he was owed to later years. For example, you can currently put money into good corporate bonds paying around 7%. Investing $400k in one of these would yield over $80k in total interest payments over 3 years, which gives a rough indication of how much Robbie may be out of pocket.
In a sense Mighty Tiger might be right when he speaks of Robbie taking a pay cut. If Robbie's contract does not include interest on deferred payments, then effectively he has taken a pay cut.
The fact that Robbie will be paid in full whether he stays or goes is true, but it doesn't diminish the financial sacrifice he may have made for the sake of the team.
I get what you are saying, but it's not as if the club owed him money that they withheld. It was an agreement to structure payments over a certain number of years, which he agreed to.
If I take a job where I agree to 25% payment in Year 1 and 75% payment in Year 2, I can't be complaining about lack of cashflow or capital in Year 1.
Robbie technically wasn't being withheld money he was owed, he agreed to put off the largest payments until last. Why would we pay him interest on those? He has not even provided the services of the last 2 years of his contract yet.
Correct me if I am wrong but my understanding is that he agreed to that so the club could remain under the cap - 2013/2014.
