What I would love to see is for the whole team to get on the same page and see the pass after the first pass from Rondo.
I still think some of the best offensive running PGs do not always get all the assists. Those are the PGs with the vision to see two or three passes ahead with a team they trust to make those passes. (I am not saying Rondo can't or doesn't do this)
Agree 100%. And in the past that has happened. Pierce KG and Allen were still making the extra pass for years. But Danny started to add players to the team where the ball got stuck in their hands. Players like Rasheed and Bass and Green and I think as Rondo grew as a player, Allen and Pierce started letting the ball stick in their hands because they wanted their shots too.
Since 2011, this offense has gotten worse because I think that extra pass is not being made.
No, during that span our offense has gotten worse because we took a smaller and smaller percentage of our shots 'at rim' and from beyond the 3PT arc. Too much reliance on long 2PT jumpers. I've done the plots - the correlation is extremely tight.
And the change in shot type corelates exactly with the absence of a consistent low-post scoring option in our personnel. We have given a lot of the frontcourt minutes to guys like Brandon Bass - who is good player, but offensively is redundant with KG's stretch big game.
We miss Shaq. 
Sully provided a small light in the tunnel last season. If he comes back 100% and regains his starting spot next to KG - that could be a big shot in the arm for our offense.
I'd love to see a fully healthy lineup of KG+Sully+Green+Pierce+RR. That unit should definitely be able to score on anybody.
I don't believe we ever played that 5-man unit even once last season - they just weren't all healthy and playing effectively at the same time.
So what you are saying is it can only be what you said and not both? If more mid range shots are being taken than 3's or post shots then the ball can not be sticking in the hands of players like Pierce or Green or Bass who do not go to the rim a lot and take a ton of mid range shots?
I'm not disagreeing with what you are saying but one of the reasons for the shots being taken where they are might be because of players who like taking mid range jumpers having the ball stick in their hands and do not make the extra pass.
What I'm saying is that that "extra pass is not being made" because there is no one consistently working down in the post to pass it _too_. And there is no attack on the rim by wings because there is no one working down in the post to push a body along the baseline or to set a baseline screen in order to expose a look at the rim for perimeter slashers. Brandon Bass just doesn't play a strong low-post or baseline game. He's always out, 12-15 feet from the basket.
Shots at the rim are generated mostly in fast break, post-up, p&R, baseline screens & weak-side cuts. We had our fair share of fast break points (we were ranked 15th in fast-break efficiency and 16th in fast-break points per game). But we had below-average share of the other plays, especially post-up & baseline plays.
Those are reflections of our lack of low-post personnel.
Note also that that lack affects the ability of guys like Pierce and Green to attack the rim.
Even with Perkins - who is not to be confused with a great offensive player, one of our bread and butter plays was the baseline screen. He was strong and could both push a defender out of the paint and pick defenders off. That probably accounted for 3 or 4 plays per game - very high percentage shots (~70%) for Ray, Pierce or Rondo. Replace those with instead taking 3 or 4 low-efficiency (~42%) jumpers and that difference eventually adds up.
