Sabrina Ionescu gets nervous. Too nervous to sleep. Lying in her bed, wrapped in her gray blankets, she’ll try to meditate. Inhale, exhale. Inhale, exhale. Doesn’t work. She’ll turn over right, then turn over left. Right, left. Right, left. Still nothing. She hardly sleeps during the season. Especially nights before games. The thoughts will just get louder in her head. What if we don’t win? We have to win. What if my shot’s off? How are they going to guard me? 2 a.m. … She’ll replay mistakes she can’t let go of, losses she’s still ticked off about.
