The Boston Celtics are two games from their third NBA Finals in five years, and for the first time in that span, point guard Rajon Rondo is the talk of the team. Rondo continues to make headlines with his triple-doubles and monstrous box score numbers, while something like Kevin Garnett‘s otherworldly 43-point efficiency difference while on the court has gone unnoticed.

And that shooting, as we’ve seen in the Spacing Effect, is an enormous part of being good offensive player. Consider the simplest measure of shooting, the open 15-foot free throw. Here’s where Rondo ranked this year among guards:
Even worse, he as an outlier of the worst kind. Among basketball-reference’s “guards only” who qualified for the free throw title, he was a whopping 13% worse than the penultimate player:..
