That's not entirely correct. The Spurs primary P&R with Tim/Tony borrows a lot of off the ball movement from motion offense, especially the cuts. There's too many combos to put in one post, and they change depending on wether it's a straight P&R (Tony does the entry pass) or a 4-down (Kawhi does the entry pass). Action really starts once Tim is posted up. There's different variations, but for example, if it's a straight P&R, you'll normally see the SF make a hard cut to the basket, screened by the other big, finishing his run on the opposite corner. The SG who was on that corner will rotate to take the SF spot on the 3 point line. Now wether the SG gets the open look depends on a lot of factors: Tim having the passing lane, the defense actually collapsing and leaving the SG open, etc. If it's a 4-down, then it's a bit different, because the SF will cut baseline and then you get a bunch of new options: either stops the run under the basket and gets it back, runs to the opposite corner (in this case, the SG makes the hard cut to the basket, and the SF rotates). There's a lot off the ball movement (or should be, it's not always the case), some decoy, some legit options. But eventually it boils down to what the defense gives you. If they're not giving you a lot, then option 1A and 1B are Tony/Tim... that's not going to change.
