just standing around. Not very many. They will on occasion have a player camp in the corner but only when there is a ton of action on the other side trying to press the rim. Every single player is trying to set screens. Not just one player every possessions but its really whoever is closest to the action. They set picks and then they roll off the picks. They back cut off the picks and take whatever the defense is going to give them. Klay is a master of that back cut. Draymond is a master of that back cut. They run pin downs to free up Steph and Poole and Klay. When they are mentally engaged in a game it is a thing of beauty to watch. They can get mentally lazy but when they are engaged it is the beautiful game.
TL;DR
The warriors win with basketball IQ. Combine that with talent and they are very very very good.
