If you look at how teams like Boston and Indiana are constructed, their offense is based on having all players being able to shoot the ball and move the ball. They still have their offensive leader, be it Tatum or Haliburton (or Siakam), but everyone on the floor can make an open shot or can put the ball down and pass off the dribble if they don't have an open shot. Doing this on a floor that's spaced out ultimately gets someone an advantage--an open look or an open lane to the rim. (Eventually, someone over-switches or over-commits.)
