I fully agree with this statement. New voices and opinions are great assets, but when the leader is young himself, I question his ability to fully extract value from those voices.
From my assessment, his experiment (thus far) has been an abject failure. Lots of money spent, great regular season success but still no playoff (though I give some credit for the TBL loss, but we're going to be a worse team next year).
He seems to be willing to go out on his shield on his top four (accidental five?) model, which hey, admire the commitment, but he's ignored some of the external factors that go into extrapolating models from more successful teams. When you can have Stamkos, Kucherov, Point, Hedman and Vasilevsky all making below market value because of a favourable state tax rate, you can't rebuild that model when you're paying out an additional 10-15% of your cap space to make it happen.
He's tried to play the analytics/puck-possession game, which I think has it's place, but he's put too many eggs in that basket. You can only put those guys on for 20 minutes a game, so hoping the rest of the squad can carry the load is a big ask when you're not given the same amount of talent depth.
