This stat represents what percentage of a player's total points come from the line. This stat obviously doesn't tell the whole story, for example, Lebron has far fewer of his points coming from the line than Curry, but Lebron's actually shot more FTA than him, he's just less accurate. Nevertheless, I do find this interesting.
