I'm sure even a Sydney fan is capable of working out 9*1.1m > 5*1.1m ? Especially if 5 would have brought you to a believable retirement age. Crooked.
Irrelevant to claims about what's affordable. The claim was a massive contract "blew others out of the water" but clearly other clubs are capable of offering just as much per year. And since the salary cap is per year, it only makes sense to discuss contract sizes per year.
And furthermore, any club could equally try the NHL style super-long contract too if they wanted. If they'd thought of it first.
