A set play is designed to get a specific shot or to get a specific player in specific area. Sets are just the general motions that team runs. You don't go into expecting a certain kind of shot. The offense has an action, the defense reacts, and then the player has to decide what to do with it from there. That's how the Jazz offense works and has worked since Quin has been here. We have much better decision makers now, you could have seen this coming a mile away. Of course Hill and Diaw are going to be making better decisions with the ball than Neto and Favors.
The Jazz aren't developing a 4 out system as much as it is that they just have different personnel. You can't run a 4 out system with Favors unless he's the only big. The entire point of a 4 out system is to have 4 guys that space the floor and Favors doesn't do that. We play differently with him on the floor, it's just a fact.
At the end of the day, it's just preseason anyways. I don't know how you can make large judgements about our offense in 6 preseason games where we were missing our best offensive players for the majority of the time. I think you can say that Hill, Diaw, and Exum are fitting in nicely, but beyond that, I don't see much of a structural change in our offense.
Our offense wasn't that bad in the first place. You say that our offense generated a lot of long 2's, but the Jazz were 25th in the league in percentage of shots taken as long 2's last season. That's not a lot, especially when consider how many possessions ended up with Hood/Hayward having to toss one up against the clock. The offense certainly isn't designed to create long 2's.
In order to get the line, you need to have the ball first. Rudy is catching the ball in much better positions this year, and it's not because he turned into Jerry Rice over the summer. He's open and catching the pass clean. Once he catches it, the defense has to let him dunk it or foul him. If they were in position, they wouldn't have to foul him.
