Why is it played great versus lit up? A jump in the average combined goals scored of say .75, is a large shift historically.
I don't understand your question. I'm not disputing the large jump in goals, I'm offering my opinion as to why it happened.
I'm of the opinion that most of the teams in the playoffs were not as good on the back end as playoff teams in most other years. I think that's a byproduct of teams emphasizing offense during the regular season, where it can be effective. Come playoff time the better defensive teams fared much better than the run and gun counterparts as I mentioned.
Let's go through the teams:
Washington isn't known as a good defensive team and had such bad goaltending they got rid of both this off-season. They were beat by a deeper offensive team in Florida.
Florida wasn't known for their defense or goaltending, Bobrovsky had a better year but certainly isn't viewed as being good/great. This team was known for outscoring their mistakes. They were able to do that in round 1 and were dispatched in 4 games by a defensively sound Tampa Bay team.
Toronto also isn't known for their attention to defense. Their goaltending was okay but is a weak spot for the organization. Despite all their offense they couldn't get past Tampa Bay
Carolina is a good defensive team but their goaltending is always suspect. Didn't they also lose one of their goalies during the playoffs? Who did they lose to? A team with a better goalie in Shesterkin.
The Rags aren't good defensively but had the best goalie in the league last season. They also had the fortune of going up against second and third string goalies for two rounds. Who did they lose to? A team with comparable goaltending and a better defense.
Boston lacks defensive depth and their goaltending is okay. Bounced by a better defensive team in the first round.
Pittsburgh choked away their series because they had a third string goalie playing and the Rags had Shesterkin. Neither team was good defensively.
Nashville lost any chance they had when they lost their starting goalie. Outclassed by Colorado, a better team offensively and defensively, just not in net.
Minnesota is a great up and coming team but they were beat by a hot goalie and the good defense from the Blues.
The Blues were playing very well and gave Colorado trouble until Binnington went down. I think they might have won that series had he stayed healthy. A good goalie was key to beating Colorado.
Calgary was good defensively during the regular season but lost a key defender and their goalie wasn't good and everyone knew it. They lost to a high powered offense that has the most talented player in the world on it.
Dallas gave Calgary all they could handle because of their goaltending. Unfortunately they severely lacked in both other areas.
Edmonton was defense optional and played two older goaltenders and an LA team without their best defensemen.
LA played hard but didn't have the defense to stop McDavid. I love Quick but he also isn't his old self anymore and can't steal a series.
I don't know, I'm looking at these teams and it's pretty clear that teams with good goalies and strong defense do pretty well. None of the high powered offenses were able to get get by teams with good defense and a good goalie. Colorado is weird because they don't have great goaltending but are so good everywhere else that it didn't cost them.
