Actually, if you watch the games, for the most part GS isn't helping on LeBron.
The #1 reason CLV is in this is because their defense has been incredible. And that's been a team effort. Curry isn't missing wide open shots. They are really into him. Even Thompson, who had a very good game was forced to make tough shots. GS has gotten very little in transition and easy, close-to-the-basket looks while in the half court. CLV has dictated pace and shortened the game. They have been masterful in this regard.
