Thompson, Green, and Curry alone are 40 million. Iggy and Bogut add another 22 million. Barnes is due for a big raise. Thus, they would need to have some fairly significant salary dumps to create the room to sign Durant and it might very well mean no Barnes. This is where a salary like Amir's becomes so valuable. Boston could trade Amir, plus some other asset for Barnes (sign and traded) or something like that. Could clear GS' salary problem and get Boston the SF it needs.
