Danny Ainge doesn't just want to win. He needs to win. One-on-one, regular season game, playoffs, major trade, choosing the right draft pick - doesn't matter. All the same to him - he needs to win.
To paraphrase Allen Iverson: Not a game. We're not even talkin' 'bout practice. This was just a friendly game of one-on-one basketball. But this was Danny Ainge, so let's take the "just" out and change the "friendly" to "competitive", and we have it right.
