It's all about routine. Pregame discussion, pregame snack, pregame stretch. Counting players on the court, talking with the coaches, talking with your partners. I do some self-talk to review PCA's and mechanics; go for a little run with 3 minutes left to get my legs working. Pop in the gum with 1 minute left.

Game time.

More self-talk: white is on defense, blue setting screens. Blue 12 set a marginal screen, watch him for next time. White 55 likes to bang in the post. Ball OOB off defense, point left. Ball off offense, point right.

The good news is you usually have a few possessions to get oriented before you have a whistle.
