As someone who made his money in math/science, the first thing Cuban did when he bought the Mavs is hire a team of statisticians to revolutionize basketball stats. For example, every team charts 3 pt.%, but Cuban's statisticians broke down 3 pointers from the different areas behind the arc. They found that San Antonio shoots a very good overall 3 point percentage, but when they broke it down the Spurs shoot great from the corners and straight ahead, but shot 3 pointers poorly from the angles. So they started focusing on guarding the perimeter baseline and the top of the key, giving the Spurs the angle shots and the Spurs shot below their typical 3 pt. average in head to head matchups ever since.
