If the Rockets get it to a game 7, I'm not betting against CP3 at home. He's money in the clutch, especially at home. However, I think the Warriors get it done in 6.
I think people are missing out on 3 key advantages that the C's have: homecourt advantage, coaching, and defense. The Garden is a hard place to win at, Brad Stevens is the 2nd-best coach in the league (behind Pop), and they have a couple of players who are capable of matching up with Lebron defensively. C's in 7.
