It's not.
It's just sexy on paper.
If we had Kane from 2010, Tarasenko from 2017, and half of what Lafreniere and Kakko were supposed to be, then yeah, we'd be the best team in the league.
That being said, I don't necessarily subscribe to the doomy "this is as good as it gets" mentality. We can and should put a better product on the ice.
We just need the front office to wake up and address actual problems that continue to fester. This organization desperately needs to get over the mentality of having a token PMD and everyone else is either Dan Girardi or a dump truck. Also, paging management: the Rangers were fast NINE PISSING YEARS AGO and have gotten slower every year since. I don't think you need to be the fastest team ever to win but we have nobody (like a Hagelin, just for example) who's gonna go in and get the puck in a game like this.
Again, I like Tarasenko as a player and Kane, analytics be damned, is way better than I expected, but were they addressing anything fundamentally wrong with this team? No.
