Lets get this one thing straight, warriors once didn't had Durant and they were down 3-1 against okc tunders who had Durant at the time and won that series (even though lost to Cavs later on). So, when going to any series even if it gets 0-3 against warriors they wouldn't panic, they still have the bigger hand with all those great players. I am not saying they will win or lose these series but there is jut no need to panic for now. Last game Durant basically single handedly brought the game closer but didn't get any help, this time they got curry playing like he used to and that wasn't enough neither because including Klay Thompson nobody really scored so two wasn't enough. They will make sure to include Draymond and klay Thompson next game too and they will win it easily.
This will depends on the scenario and also the momentum of the series itself. The Golden State that time are hungry for championship although at the end, it was the Cavs who triumph that season. They were down by 3 and they told the Dubs Fans to go inside the arena as early as possible, as far as I remembered this is what they've done. They worked hard to get the momentum back on their side.
