I don't like the "finding a way to " win/lose narratives. We lost the game last night a lot because we turned the ball over a tremendous amount and a little because Marcus Smart got into a p---ing contest in crunch time with a better player. If you wanted to pick one single thing that swung the outcome of the game, I'd say it was the amazingly bad performance of Evan Turner.
Some extra turnovers should be expected when you are playing as aggressively and pushing the ball up the court as hard as we were, but we also saw some really loose handle and bad passing from the likes of Turner, Green, Bradley, Rondo, and Smart. Hopefully they can tighten things up as the season progresses, because all of those players (except for Turner) have a lot of good things going for them.
