Edit: no idea how this worked, but I now assume you meant how many games will be played to decide the winner? Not how many will one side win? Im guessing it will take 6 games, before one has the required 4 wins. Is this how it works?
Edit II: I noticed that when the Heat win, ts by a few points. When Spurs win its usually more than 10. They seem to have the upper hand. I havent seen the latest score, but did hear Spurs won it.
Ive changed my prediction to Spurs n the same 6. Heat will manage one more.
