Here's my piss-poor analysis.
1) The Hot Start: 15-1-0. The hot start was difficult to evaluate. The 5v5 numbers weren't great. The powerplay was unreal - converting at 42% during the streak, especially coming after last year's 19%. The goaltending was also unreal: .928 in all situations. In this economy?
Analysis: A few unsustainability red flags were apparent, but there was a lot of crazy stuff happening. I mean, I don't think anyone was expecting a 76-6-0 - although that was still on the table before the game on December 1!
2) The Slump: 6-8-1. The slump ran from mid-November to mid-December. Sure, you could argue that some of it was schedule related, but some regression chickens came home to roost at the exact same time. The powerplay dropped to a Lauerian 19%. Goaltending was an un-Hellebuyckian .899. The meh 5v5 numbers got worse.
Analysis: Tough schedule but some expected regression too. The real Jets are somewhere in between the two extremes. The only question was which end of the spectrum they're closer to...
3) Post-Slump: 15-5-2. In the month and a half since the slump, all-strength goaltending is back up to a .916 (3rd best in the NHL since mid-December), the powerplay is back up to 38.5% (!). 5v5 numbers are back up (xGF% is WAY up into elite territory).
Analysis: Goaltending is elite and it seems reasonable that it can continue, considering Hellebuyck. The 5v5 numbers are encouraging (and a big reason why a lot of power ranking models increasingly like the Jets). I'd say the powerplay is highly unlikely to continue converting over 30%, but regardless, it's still a pretty good powerplay. PK is the Jets weakest link...the results are meh, and the metrics/analytics are mostly bottom 10 - but the good news is that the Jets don't take many penalties, so that reduces the impact.
