Do not ask Phoenix Suns center Deandre Ayton to watch the N.B.A. away from work. He doesn’t want to see other teams play. “I just can’t watch it because I have principles when it comes to this game,” Ayton said in a recent interview after practice. “And, you know, I’ve just seen too many principles and bad habits that it messes with me. So I don’t watch it at all.”
