just choose your team like you want, and buy a PG with no shoot ... Else no coach would say, don't shoot if you don't have a open look.
And for me a attack run like this, you could several oppurtunities to score combined with a probality to finish it succesfull. If you play outside Focus you get a bonus of finishing outside and maybe more oppurnities there, if you play a fast focus the players would take a more difficult shoot(and with less time on the clock). So if your PG can't shoot he would pass the ball instead of shooting it(look for veltins in my team, he has only mediocore attack which is crap in my league, and he takes nealry no shoots, but he rebounds well and makes good assist for an center).
So why let your go to guy shoot more unsuccesful shot then your PG does, when he is an better offense Player he would take more shoot or you could play a lower pace(when you think he has better oppurtunities to score, then your PG).
