Good Lord Curry looks ridiculous already.
The lead isn't that much, but OKC doesn't even look in the same league as Golden State right now. They're just flat-out better on each side of the ball, especially the defensive side at turning the ball over.
To beat Golden State, you have to have a defense that forces them to turn the ball over, which is already a weakness for them, puts pressure on their perimeter scoring, and turns their turnovers into points. I just don't see OKC being able to do all of those things.
