Maybe I am slightly over, but I think you are underselling by a bit.
Going by your methodology, the third party endorsements and incentives must be quite high to have the team they have on the above-mentioned base salaries.
Remember that graph that got published last year showing the clubs so called 'Third Party' contracts?
Roosters were right at the bottom in terms of what their players 'earn' via third party contracts.
Again, not guaranteed source of truth, but reports had Cricton at $1m (Which is hilarious in itself as he is SO overrated) and while this might be inflated, I would have to think it would be more around the range of $800+. Keary I would also suggest is higher than $700,000.
And where is Cordner in this mess? Current NSW and Australian captain? Must be at a minimum $500k
Its a farce and everyone can see it.
