“ The flow. Yeah. Knowing you could step on the court and make it happen. You practiced, sure. But then, when you walked out there, you could just go. You could flow, that was it: you created and you didn't totally know how. You just knew you could, so you did. It wasn't thinking and it wasn't imitating somebody else's moves, though you always looked carefully when you watched good players play. But when you played... it was something you couldn't explain. Neal used to know. It didn't come from thinking about it. ”
