Yeah, you guys are probably right that its just the sublevels. I forgot about the effect of rebounding on salary. Isn't it a little odd that rebounding bumps up salary by 2500 but passing does not raise salary at all? I forgot about that non-intuitive case with the guards in BB.
I copy pasted the salaries to the new salary calculator and player A must have really low sublevels to be stuck at that salary and player C must have really high ones on all the valued skills. I thought something like that would be unlikely which is why I asked whether there was some random factor to the salary calculation. But its certainly possible so thanks for clarifying that.
