When you're losing 6-0, particularly the way they won, a lot of things had to go right for them. If one fewer thing goes right, a strike call in the 9th for example, and they lose, they're no longer the better team?
I will give you that they are the more fortunate team. Literally, fortune favored them.
5 games is not enough time to see who the better team is.
So you're the type that loses best out of 5 and insist to make it best out of 7 and on and on until you win.
Sack up and accept the loss.
