Spurs rely on hot shooting. They need Mills and Green to get going from 3. If that happens early the Thunder will be playing 15pt catchup the rest of the game. The TP/KL/LMA connection doesn't work very well when guys aren't taking the open look. All those passes are to get that open look, but they up fake, put the ball on the floor, get trapped, pass out of to a wide open shooter who hesitates, up fakes, drives in and looks lost again.
Pop's simple message should be "if you're open shoot the goddamn ball and we'll live with the results, I do not want to see anyone refuse to take an open look in their zone. Don't expect to get great looks, get good looks, shoot it, get back in transition."
