I've never seen a consistently successful NBA team base their offense around the 3-pointer. What you do is implement sets that get you high-percentage looks at the basket and create the spacing and floor-balance so when defenses start helpingthen you can make them pay.
Perhaps I was watching a different Utah Jazz team, but from 2007-2010 much of Utah's oustanding offensive efficiency was based off the spacing that their ability to hit the 3pt generated - particularly in late-game situations. First Memo and then the aquisition of Korver really opened up the offense - and both sides fed off each other, the shooters created spacing for Deron/Boozer and Deron/Boozer created open looks for the shooters.
A free-flowing motion pick&roll offense with shooters from all spots could be used to describe the Spurs - if you have Tim Duncan, Tony Parker, Manu Ginobili and Greg Popavich, but it could also be used to describe any Don Nelson or Mike D'Antoni team as well.
You'll be more successful if you have players/system that consistently gets you high percentage looks at the basket with subpar 3pt shooting on the perimeter, than excellent 3pt shooting and nothing of substance inside the arc. If 3pt shooting was the cure-all that it's being made out to be, the Orlando Magic would've won a title by now.
