The fact that the Mets won(even in a sweep) doesn't make them a better team, if you believe otherwise you don't know what you're talking about.
And "pitching dominates in the postseason" is more nonsense btw, yes the post season allows you to get more starts from your aces but that's not what happened here. And also the Cubs trio of Arrieta, Lester and Hendricks is almost as good as Degrom, Harvey and Syndergaard. Why did the Cubs not benefit from this "pitching dominates in the post season" effect. Arrieta after all had one of the best non Kershaw seasons in recent years. Here are the xFIP's, 2.61, 3.06,3.25 vs 2.92, 3.24,2.91. You wouldn't know which set of starters belonged to which team without looking them up.
This is basically what bad punditry is built on, a lot of generalizations based on no evidence and post hoc fallacies left and right.
