Game 7 For The NBA Finals

While I didn't make any formal predictions, I could have seen this NBA final going 7 games at the beginning of the season. 7 games equal more revenue for the NBA and I am very jaded with the NBA. They are just one step below the WWE wrestling in term of ethics.
So, who will win game 7, my hope is the Celtics.
And I predict that the next season NBA final will also go 7 games.
