Off-ball movement and pace seem to be the biggest differences to me on offence. Reminding me a bit of Golden State's offence over the last decade or so, with lots of double screens set for shooters. Either get an open shooter, or the defence over-corrects and one of the screeners flashes to the rim for an easier shot.
I always remember a couple of useful quotations from Chuck Daly, who was something of a quote factory:
"Defense can't guard two things in a row."
"Defense doesn't break down on the help, it breaks down on the recovery."
Your connection with the recent Golden State offense is a good one, I think. In fact, that reminds me of another Chuck Daly quotation:
"Offense is spacing and spacing is offense."
