You are right, but we have not demonstrated that yet. We are seeing promises. 1-2 games do not erase 35 games IMO.
As far as my understanding goes, goal differentials are not good predictors of future success, basically that is why Corsi etc are preferred.
The Ducks weren't exactly mighty in this game either. At least the Viasat commentator was making remarks about the poor play.
There was a lot of refreshing stuff in this game too though; ELL, 2nd PP, solid turn-around games from Little and Ehlers, good defensive effort were it not for defensive lapses at times.
1st PP had a generationally bad shift. That was a sight to behold.
