Well mate, this isn't strictly true when you consider the variables are potentially different. The likes of Boris, Kawhi and Tiago will have a full training camp to become more acclimatised to the system. Our rotation could look different with Mills potentially getting the backup PG minutes instead of Neal. Green might be more consistent and allow for Manu to stay with the second unit etc...
There's other factors to consider such as matchups and injuries. OKC might get knocked off by another team before we play them.
Also, as The Cobra mentioned a few posts earlier the Spurs aren't necessarily done making moves.
