Basketball is not a democracy. Everyone does not get the same amount of shots. But getting everyone involved has advantages.
In the next Bob Cousy Basketball Concepts and Techniques, he shares a play for the 2.
Obviously, many plays have additional options. One obvious one would be 'scissors' action for the 2 and 3 (conventionally, the passer cuts first). A second, would be "triangle" action with the 3 cutting baseline and the 2 to the middle. If nothing emerged, 5 could reverse the ball to 1 and 4 go to the elbow...voila...pinch post.
