For the main part it is true, but it depends on individual contracts. For example, Dangerfield is on roughly 850k a year, he's now on over a million.Sadly , I don't think that's the case. If it was reported right , I heard that min wagers are guaranteed a certain amount , but otherwise it's up to individual clubs , as to how they dole it out.
Adelaide on the other hand didn't have that clause in their contracts so will have cash to splash.
