If Manly can offer $1.1 Million then it's not a giant stretch to add $700k a year in endorsements and appearance fees as 3rd party payments.
One team cities ( especially Brisbane & Auckland) have a huge advantage over the Sydney teams as far as being able to offer a myriad of these deals.
I remember when Lockyer was supposedly getting $250k a year in his last two years , well he was on every second TV advertisment up here and there would have been a dozen different billboards with his image on them, and you can bet the real figure was closer to $1 Million a year.
So yes I reckon $1.8 is doable.
