The 2017 Houston Rockets have perfected the pick and roll. James Harden has mastered the action, and Daryl Morey has surrounded him with a repository of shooters and several big men willing to screen and dive to the rim. If you provide any help, you’re leaving lethal 3-point shooters open. If you double or hedge too hard, you give up a lob dunk to the rim. If you go over and have your big man back up and give Harden room to operate, he will needle his way to the basket and draw fouls. There’s no good options.
