After reading the entire thread, I'll make a couple of observations/comments:
Tom Dundon reflects the team building ethos when he said shortly after buying the team, and I'm paraphrasing, "...our job as management is to find the best players and your job as players is to make sure you're one of them". What was different about this season was that the "best players" were the ones that best fit the system.
The difference in this year's Canes team from recent versions is pretty stark. They got bigger on defense (although all of their defensemen aren't big) and they simply scored more (2nd in the league after Colorado).
Related to both depth and scoring is the fact that the Hurricanes had 7 players who scored 20 or more goals (and 13 with 10 or more goals), yet none that scored 40 or more. They had 8 players with more than 40 points (and a total of 12 with more than 30 points), yet none with 90 or more. The "4th line" put up 30 goals and 57 points. Yes, the entire team forechecks like mad, but the offense came at teams in consistent waves.
Lastly, it will be interesting to see if there is a change in drafting strategy. The Canes likely felt they were exploiting an inefficiency in other teams' draft strategies by taking a boatload of Russians. Many teams shy away because of the KHL contract situation. Also, in the past, teams controlled Russian players forever. That last bit has apparently changed in the latest CBA update.
The Hurricanes are in an interesting situation as they have almost $12 million in cap space and only a couple UFAs (who may or may not be signed). Alexander Nikishin is really the only guy we have to sign (he's an RFA who is not eligible for an offer sheet). Down on the farm they have 3 or 4 guys who are likely ready for the NHL (Nadeau, Unger-Sorum, Legault, and Nystrom), but it is hard to see who on the roster they would replace. Suffice it to say, it will be an interesting off season for Carolina.
