I’m not sure of the way to research this, but James Harden is, I’m sure, the best player at ending quarters and halves in the NBA. No one is better at getting 2-for-1s, and he always attacks the basket when he can to ensure, at least, free throws.
With 11 seconds left, Harden got a pair of free throws. And after the Rockets allowed an easy basket (sigh), The Beard did the above. Example No. 5,000 of his basketball genius.
