In regards to the ball sticking -- I think you can excuse that because, as the C's are currently constructed, Rondo's penchant of passing for the assist (which is real) constitutes the best possible opportunity to put points on the board. The Celtics are really, really bad at scoring, and more ball movement, rather than more player movement, isn't necessarily the answer.
I'm into this thread pretty late, but I wanted to quote this for emphasis. It is dead-on correct.
The Celtics were a
horrific shooting team last season -- tied for second worse in the league at a miserable 43.5% FG%.
Yet, when taking shots off Rondo's passes, the team shot an excellent 49% FG% (slightly better than the Spurs' 48.6%).
And your very last words are critical. The principal behind a motion offense -- which is what the Spurs run and what Stevens wants the C's to run - is
player motion, not necessarily ball movement.
Finally, just to address the difference in touches per game - well, a big part of it is Rondo played in more _minutes_ per game (33.3) this season (in the games that he played) than Parker (29.4).
When you do the math, you find that Rondo and Parker held the ball very nearly the identical amount of time per touch of the ball and as a percentage of their team's possession time when on the floor.
Also, for what it's worth, when Rondo was on the floor, his team generated more shots per minute than the Spurs did with Parker on the floor (in particular more 3PT shots), The big difference being that the Spurs have a bunch of really, really, really good shooters taking those shots while the Celtics did not. As I pointed out above, the Celtics were much better shooters when taking shots off Rondo's passes. Unfortunately, he could not stop his fellows from sometimes taking (bad) shots independent of him.
