Last game of the finals should go to the Golden State Warriors they have every advantage on closing this series and Cleveland Cavaliers gonna have a hard time in dealing with gsw on their home.
This is always the case when it comes to basketball finals. The major winning factor is the home court advantage. Once the crowds gets into it there is no stopping a team that is striving for the win more so for the final and deciding game which is game 7. 
Home team wins sometimes, not necessarily because of the audience, but they do have the potential to win it.
Yes, cheering helps in winning, but to what extent? Does GSW guys not have that will to win this?
But the bookmakers odds are against them to not win it.
Will just watch and look who will walk away with it. That's about all you can do.
but with the final winner its really hard to bet with. good luck guys.
