Most of it is basketball-based, as Parsons often shoots and watches film with Carlisle in one-on-one sessions. But they also socialize some, having attended concerts together and shared many meals, occasionally with Carlisle’s wife and daughter and Parsons’ parents and/or longtime best friend/personal assistant, Pausha Haghighi. They’ve also played late-night ping pong on the table in the Mavs’ locker room. (Parsons and Carlisle both swear they won the three-game set, and Carlisle complains that “my table tennis brethren would be disappointed with his [illegal] serve.”)
