After this year we have picks our starting center is going to be Jones and he's on a rookie contract.
Those first rounders are guaranteed contracts, there's no real way around paying the luxury when you have 4 guys that will take you over it by themselves.
Breh, Jones has played 10 games in his career, they aren't starting him. And there's also the prospect of Klay coming up for his max in 2 years too, at that point Curry & KD will be making 70-80% of your cap.
