Again, he's still going to be battling for touches. Just because he's going to be running the offense doesn't mean he's going to be one of the primary offensive options - all the other players will need their fair share of touches to develop, plus Fultz, Saric and Biid all can create their own shots. It's not going to be a case of everyone stands and waits until Simmons sets them up on every possession.
The 76ers were #1 in passes by a HUGE margin last season (yes, that's partly because they didn't have a legit PG to run the offense), but I don't see a drastic change in method next season - the ball is still going to move regardless of who's playing PG. Brown's a Spurs guy, he's incorporated the same principles from SA into the system in Philly.
again: he's not battling for touches if he's running the show....for the most part, the offense is gonna be running through him, so he's gonna have the ball in his hands the majority of the time, setting up the offense, etc., being the primary option...and that's not battling for touches....and no, i'm not saying people gonna be standing around waiting to be setup by ben, just saying he will initiate a lot of the offense...which adds to his roy case....
as for them developing: the game aint the place to 'develop' players....that shyt is done in practice, workouts, training, etc...the game is the place where they gonna execute the shyt they learned, and again he's gonna be running that show....side note: as for them developing, i think it would be best they develop as a team, to push each other while getting that chemistry....
even running the spurs type offense, where the ball moves around, there is still 1 guy it tends to flow through....whether it was duncan, parker, ginobli (sp), and now kawhi....the same is gonna happen in philly with ben...they will move the ball around, but it will flow mostly through ben, then embiid....but even then, embiid has to have someone give him the ball, and in most cases that will be ben....
