There are two major differences in the above examples and the Pacers situation, which I'm sure you'd agree with:
1) O'Brien ran the pick and roll MUCH more frequently with Philadelphia than he does with the Pacers (hence the assists and extra penetration)
2) Both Allen Iverson and Paul Pierce were the star players on their respective teams. Darren Collison is not.
Of the many common threads in all of Jim O'Brien's offenses, one of them is that the star players, the focus of the offense, are the ones allowed to dribble until the clock runs out. Pierce did it (and Walker to an extent), Iverson did it, and Granger does it.
Other than that, there are very few rules/disciplines to O'Brien's offense, especially with his point guards (other than looking for the shot first and shooting lots of threes). I disagree with Count's notion in another thread that O'Brien had a different plan for each of our point guards. He doesn't have much of a plan..what we saw from Earl last season is exactly the way he played last year while Scott Brooks was early in his tenure as a coach. What we saw from T.J. and A.J. was non-disciplined play.
IF we play the same style of offense this season as we have in the past, we're going to see the same Darren Collison that we saw at UCLA under Ben Howland's non-disciplined offense. And that's a lot of dribbling.
A lot of this sounds negative, and I understand why. I like Collison and I've been one to suggest getting him over the other options. Read my past posts. I just think people should temper their expectations on what Collison will do this year. Maybe he'll surprise me and show me I'm wrong, but point guard is not a position where a player will flourish in O'Brien's current system.
