You don't have to like it because the Warriors will not lose game 5, mark my words, I will bet my life savings for the Warriors in game 5 (KIDDING!). But seriously, this is the best spot to back the Warriors as they are back home and their chance to win at home is bigger than in the road.
Actually, both of them have the equal chances of winning the Game 5 later. It doesn't matter whether they play at Chase Center or TD Garden, the chances are still equal as both teams have won in both road and home games. Of course, that's not where we decide where to bet and experience will always matter and the Warriors have that. I might bet live games as I'm still undecided where should I bet because neither have won 2 games straight.
