They've demonstrated they were by far the best team this year, the reason? They are the only team that has 3 players who can take over and carry the team when the other one is not doing well: Duncan, Parker and Ginobili.
They made the difference all along.

It was remarkable though, tactically speaking, how the Cavs played the last 2 minutes of last night game; there wasn't enough time nor they were lucky either but they were close; if you ever wondered how you would play the last minutes of a game where your team is down in the score but still with chances to win, they wrote a manual yesterday.
