I don't think I've ever heard of a team adjusting their effort and ability to win games, based on trying to determine a playoff opponent.
I can hear the post series interviews right now.
“I thought we played well enough to win but we had small lapses of 3-5 minutes where we let our guard down each game and they capitalized and got a couple by us, it stings but we will learn from it.”
“We had a ton of chances to extend the series but their goalie was really on his game, we hit a few posts each game and if one or two of those go in we are talking about the next series instead of next year.”
“It’s a tough league, you need to score 5v5 and you aren’t always guaranteed to get a PP in a game, we didn’t get many in the series and we generate offence through the PP.”
“I definitely needed to make some more saves, I let the team down, I need to hold the fort when we aren’t getting goals in tight games. I’ll be a better goalie because of these playoffs, but it hurts”
