Bah, RB, you aren't the leader. Inferno and I have been there for quite some time.
In all seriousness, the bolded point above is key. A youth movement is
not purposefully causing the team to become bad simply in order to move our picks up in the ranking; it's trading established vets for younger players and picks (and some dead weight) and allowing the chips to fall where they may. Will that perhaps (likely) lead to a worse record for a year or two? Sure. But you play through that and come back stronger. Classic example: the Yankees in baseball over the last couple years.
Also, it's not about getting rid of everyone over 25 just to get rid of them; it's about maximizing assets. Nobody wants to pay up for player X? Okay, you hold on to him rather than getting pennies on the dollar (e.g. Nash last summer), at least until the very last TDL before the player goes to UFA. So, if I were running this zoo:
Raanta: gone today before 3pm (due to Expansion Draft).
Stepan: gone before 7/1 (due to NTC).
Nash: gone, either now or at the TDL.
Staal: gone ASAP. If you can't make a deal (including retention/sweetener if necessary) over the next 12 months, buy him out next summer.
Zucc: gone sometime during the next two years.
McD: gone sometime during the next two years. Originally I was not as dogmatic here as RB - after all, this is a world class player in his prime (and on a sweetheart contract). But by the same token, that makes him the most valuable chip we have. You HAVE to handle/time this right, but he can be the key to the whole thing. Offered to the right team at the right time, and he should return a massive haul...
Kreider, Hayes, Miller: depends on the offers. I'm not in a rush. Make me a solid offer, and you can have them, otherwise I'm content to keep 'em for now. (Reevaluate in a year.)
Lindberg, Fast: solid organizational guys. I expect one of them to go in the expansion draft. The other can stay to provide organizational glue or go to help with a deal. No urgency here either way.
Skjei, Zibanejad, Buchnevich, Vesey: stay put, barring massive overpayment (ranked from most expensive to least).
Hank: most difficult of all. In the end, to me it comes down to what he wants. If he wants to retire a Ranger, he deserves that honor; if he wants a shot at the cup, you accommodate him.
