It's also silly to think of "pick-and-roll" as if it were just a single play or move. For example, saying that the most recent Spurs teams were "nothing more than a high pick and roll" indicates to me that they barely watched that team, or if they did they weren't paying enough attention.
"Pick-and-roll" is just an action on the court, that is used in dozens of different ways across hundreds of unique plays used by various teams. Every single team in the league uses pick-and-rolls in some fashion. Even the most basic possible pick-and-roll, you have endless variations, depending on what the other 3 players are doing, whether the player setting the screen sets a hard pick, slips the screen, flips the screen, rolls and passes, rolls and scores, sets a screen for a second player, etc. etc. Heck, most plays that begin with a pick-and-roll are using it as a feint for a secondary action. Boston fans should recognize this: it was one of Doc River's pet plays. A Rondo/KG or Pierce/KG pick and roll at the top while Ray Allen runs against a secondary screen at the baseline. The Rondo/KG pick and roll is designed only to attract player's attentions while Ray Allen sneaks open.
Teams like the Spurs do even more sophisticated things. For example, running double pick-and-rolls, where Ginobli/Duncan run a pick-and-roll up at the top of the arc, but Duncan slips the screen and sets a secondary pick for Parker at the elbow, and Parker curls around the pick into the paint, either scoring or passing off back to Ginobli.
Not only does every single team in the league run multiple pick-and-rolls per game, but most of those teams use pick-and-rolls in different ways in different plays with different end goals and contingency plays. And this isn't even taking pick-and-pops into account. I think it's useless to talk about an offense based on the "pick-and-roll" without also considering how and in what contexts they're used. The Miami Heat used Dwyane Wade/Lebron James pick-and-rolls to force switches and create mismatchs for one or another player to take in an iso or post-up. The Spurs use pick-and-rolls for misdirection and to initiative sophisticated multiple-action multiple-pass sets. The Clippers use pick-and-rolls to give Blake Griffin room and momentum to improvise in the paint (either with post moves, passing, or pure athleticism). The Golden Warriors use pick-and-rolls to give Curry open off-the-dribble three-pointers. All of these are variations of a basic pick-and-roll, but are all incredibly different basketball situations.
