The Spurs have not always gotten the most bang for their buck out of the gravity of LaMarcus Aldridge’s post ups. Despite the fact that he consistently draws double teams, the Spurs have typically responded with very vanilla schemes to take advantage of the fleeting opportunity to play 4 against 3 on the rest of the court.
On their first play against the Knicks, though, Jakob Poeltl used one of the simplest ways to attack a double team in the post to get an easy layup.
You certainly wouldn’t want to show this defense in a clinic, and the Spurs exploit the mistake perfectly.
