It really don't matter there will be so many teams that will go in the luxury tax next year that includes us due to this year big jump in salary cap. Anyway I believe next year is the year that the union can opt out there agreement with the owners I see lock out coming.
I don't know the answer to that, but ESPN posted an article talking about how likely GS is to break up their 4-headed monster after next year due to the lowered cap. Durant, Curry and AI are all free agents next year and at least 2 of them will command max money (in addition to Thompson's and Green's huge contracts). This GS experiment may be short-lived at best.
