I don't think the Warriors ever for a moment thought the outcome was in doubt. A series might be a 5 game gentleman's sweep.
I definitely disagree with your first sentiment, but not with the second. I've never been more confident in our ability to beat them, but it doesn't mean we'd be favorites.
Their flex half-court offense was not working. When we slowed down their game, they were forced into pick-and-roll heaves. Granted, Curry is the best at those, but there are even tweaks we could do to get them off the 3 point line there.
That's the second game in a row that our wings have held Thompson and Durant in check. I don't think we can stop them, but it does seem like we have a beat on what they are trying to do -- and we are making them uncomfortable when they are doing it.
After that, the only player in the NBA who can go toe-to-toe with Curry is Irving.
