Durant ($51,179,020), Beal ($50,203,930), Devin Booker ($49,350,000*), Jusuf Nurkic ($18,125,000), Grayson Allen ($15,625,000), Nassir Little ($6,750,000) and David Roddy ($2,847,240) are all under contract for the 2024/25 season, without any option years to worry about. This is most of the top half of the rotation, and although the sizes of most of those deals will make them harder to shift if a substantial makeover is forthcoming, it does at least likely mean some stability and reduced roster turnover going into next season.
What becomes harder is finding ways to improve the team externally, given these self-imposed spending restrictions. It seems certain that even in the most generous offseason hypotheticals, the Suns will be operating far over the luxury tax line, far over both aprons, and far, far over the salary cap.
This, then, will prohibit much spending on new salary. The new NBA Collective Bargaining Agreement is deliberately punitive towards the largest spenders, both in terms of luxury tax payments and also in terms of what mechanisms are even available. The Suns cashed in most of their chips to get to this point, to the point that the Beal trade was cobbled together with a myriad of second-round picks and pick swaps to compensate for the lack of available draft capital. With so much of that gone and with so much salary already committed, the roster situation is illiquid, and will require free agents taking discounts.
