This is the first season since sloan left that Jazz have shown a positive direction, the begging of a turnaround if you will. We still don't know who QS is, but we have had a taste.
I don't know if at some point we add pieces, or if guys just get it and it "clicks" all at once, but I see the Jazz as in the middle of a process, not getting close to finding their potential. A lot of players are in the midst significant improving/learning: Trey, Rudy, Hayward, Kanter, and Favors. Maybe some others to a lesser extent. There will be also stretches when it looks like they are regressing, perhaps like Dante lately. I am highly encouraged that they are putting it together more and more consistently.
I think QS has a long term vision for this team. I imagine that he is implementing it in bite size pieces. He patiently waits for guys internalize one concept, and begins to work on another. I think all of the aimless passing at the top of the key is part of this. It probably has just enough use at this point in time to be able to sell it to the players, however that instinct to keep your head up is the first step to creating a highly efficient offense. I have been watching guys like Burks who had to entirely deconstruct his game so and rebuild his instincts. It caused him to become a worse player in the short term, but was begging to add more of a consistent 3pt shot to his arsenal and he was learning to play off the ball a bit making him more versatile. I have a feeling QS has a lot of things to implement that the team is not ready for. Because of the progress thus far I am comfortable with his judgement and look forward to the next rabbit he has in his hat.
Because we are learning/developing, we will not be running like a well oiled machine all the time because we are trying new things. There will come a time that the players start to know where there teammates will be before they make the cut, and will have exactly how they will defend each situation as a team. Then we will be one of the teams that others try to emulate. Right now we are on a journey to get there.
So to respond to the op, for all the passing we do, we really lack the execution (assists), but you have to learn to pass before you can get an assist. The assists will come.
