Anaheim basically got better goaltending and more timely scoring. Definitely looking at a longer series if a few small variables swing the other way.
That being said, Anaheim was missing it's most relied on Dman in Fowler and another top 4 guy in Vatanen, with Lindholm also banged up. I think it speak volumes that they came away with a sweep regardless of how they pulled it off, and they should be that much stronger next round after some much needed rest.
