It seems to be more common now that teams fluctuate from having a great year followed by a so-so year even with (mostly) the same roster. Hell, Tampa didn't make the playoffs a couple seasons ago and were basically written off, make it again and considered contenders quickly, shit the bed this year and probably next year will win the cup. Nashville was in the Finals 2 years ago, considered the ultimate contenders the year after, this year looks like a first round bust.
Whether that is league parity, other teams figuring out the systems and applying it the next season, weight of expectations etc etc I don't know. Probably a bit of everything.
Toxic fanbases, impatient fans and media over-analysis of slumps etc aren't helping much. 30 years ago we were ecstatic if the Jets made the playoffs 2 years in a row. Hell, we would have been 5 years ago. Social media and access to way too much information is making just about everything unenjoyable for all parties involved.
Lot's of things to be encouraged about, especially how Laine stepped up his game in the playoffs.
Better luck next year. I have grass to reseed in my backyard and chicken wings that need to be BBQed. Enjoy the summer everyone and don't let hockey get you down too much!
