Aristotle observed that “We are what we repeatedly do. Excellence, then, is not an act, but a habit.” On opening night against the Lakers, the Warriors were beyond excellent. On offense, on defense, from the big plays to the little details. But in the post-game press conference, after praising his team from top to bottom, Mark Jackson talked about the importance of turning good plays into good habits. He nit-picked a little bit — mentioning blown defensive assignments and sloppy possessions by the third stringers in the depths of garbage time — because that’s what elite teams do. They search themselves for weaknesses, and they eliminate them. The Warriors were dominant in Game 1. If they make performances like this one a habit, we have quite a year ahead of us.
