He's still regardless of offense a ball dominant player. Within the offense he is BAY FAR the most ball dominant player.
And since Harrison Barnes was in that offense the context is what matters. Barnes wasn't getting many touches and he definitely wasn't holding the ball or taking dribbles.
You seem like a pretty sharp guy so surely get what I am saying here and would agree going form a 4th or 5th option at times in GS is a far cry from being the 2nd or 3rd option in Dallas.

Wouldn't pull for me just now. It's a massive database obviously.
And
context is what renders your application of the term "ball dominant" meaningless.
I was able to access the database and after looking for myself, I quickly realized you simply aren't painting the whole picture.
Only one team in the entire NBA dribbled less per touch than the Warriors, meaning, the ball wasn't touching the court much as it's being passed around (a notion supported by the fact they led the entire league in team assists).
You mention Curry's average number of dribbles-per-touch, as if it's an inordinate number, yet you fail to provide the context that he's ranked
93rd IN THE LEAGUE in that category, lol. He's also ranked
97th in the league in average time-per-touch.
Of course he's going to lead his team in those categories. Why? Because someone has to. As the PG, he's going to have his fair share of touches taking the ball up the court and dribbling. Even then, his numbers comparatively with the rest of the league aren't even in the same stratosphere. And if you look at Shaun Livingston's numbers, the backup PG, you'll see they were very close and not this huge delta you were making it seem.
In regard to Barnes. Yeah, Barnes wasn't dribbling much because he's evolved into a spot-up shooter. While his dribbling has improved since his college days, he's still not comfortable trying to create his own shot or take guys off the dribble. He's best in transition and as a spot-up shooter which limits his offensive potential.
