Firstly, The best rugby player in the world (or believed to be) gets one million a season, This is the Jonathon Thurston/ Lockyer Equivalent of Union, So no way would SBW get 300k more than him let alone match his contract.
SBW has heaps of sponsors in Aus, He's a relative unknown in France = less sponsors if any at all for that matter, also less jerseys sold form his name like he would sell because of him here, so I don't see why toloun would pay him even 800k based on that.
Third, I think this has only happened because Nasser wasn't getting a cut of the pie so he brainwashed SBW into getting a new contract ala go to France.
So in essence, SBW chose nasser over The club the nurtured and made him what he is.
