You cite zone defense as though it's drastically changed the NBA - but it's rarely deployed.
You say most shots taken in games are three pointers, but they actually make up 18-22% (over the last decade) of them.
And you say KG and Rasheed take over 40% of their shots from three. Kevin Garnett takes 3.3% of his shots from downtown. For Rasheed it's just under 25%. Both are career stats....
