There's a difference between saying the Spurs aren't running good schemes to get him the ball and that the other four guys should have it in their heads to pass him the ball. No, the Spurs aren't running good schemes to get anyone good looks. I've been talking about this forever now. But in what the Spurs are running, the guys aren't getting the ball to him for a number of reasons, and a lot of those aren't about the personality flaws and lack of skill in the other guys on the court. And yes, some of it is the desire to break off plays to get "good" shots. Sean talks about it all the time, that plays are supposed to get guys open and if you see a guy open you should break off the play and give him the ball. That's not bad advice, but it comes with unstated assumptions that may need to be stated sometimes. The "open guy" needs to be in scoring position, and the pass needs to be high percentage enough to forgo a better pass that should come up further into the play. Like if the guys are setting up a PnR and Wemby is at the three-point line calling for the ball, why is passing to him the right move there? It can be, depending on where his man is and the general context of the game. But also a Wemby three isn't really the best offense the team can get right now.
Like we all can talk about times like when Vassell missed a wide-open Wemby on the break during the play that eventually ended with Wemby dunking on Sochan. That's obvious, which also means it's straight-forward to correct. What folks can often ignore are entry passes that result in turnovers because the pass was ill-advised or there wasn't a good target to throw the pass. That ignores how many entry passes wind up like 20 feet away from the basket, which is one of the worst spots on the court for contested jumpers. So yes, you need an offense to get Wemby the ball quickly and in good position, but making that offense work requires commitment by the whole roster, including Wemby. He has to learn how to time is seals and when to call for passes just as much as the other guys have to learn how to space for the entry pass and when in the rhythm of the offense their passing windows come up. I personally would rather their offense run like that for a while even at the expense of times when the defense breaks down prematurely. I think they need to retrain/train their habits to fit in a more organized system before they start free-lancing again. I don't know if Pop is going to try to pull the reins any, whether we're talking about this year or in general.
