That isn't at all what I said.
Obviously, the rest of your post is just more Aardsy Conjecture, so there's no point in addressing it.
The blue line depth has been an issue for a while now - not just this season. Losing Myers only exacerbated that. Adding a depth piece via trade could've helped lessen load on the rest of the defense, especially when you consider the minutes being logged by the two top pairings. Case in point: the Flames gave up next to nothing for Stone (to a division rival, no less), who adds immediate depth to their back end.
When you consider how defensively poor the team has been (I'm not taking away from the forwards' issues there, to be clear), it makes little to no sense for a GM to sit on his hands. And the defensive depth within the organization leaves something to be desired not only now, but looking ahead.
How much do we have invested in D on the big team right now? Who can you trade for that will be an effective, affordable replacement for our injured D, and what do you do with them when our D gets healthy?
Players in the A are either development players, or backup, almost NHL level players. Last year we had Harrison, this year we brought in Strait for that role, to add to Stuart.
Our top 6 is supposed to be Buff-Enstrom, Trouba-Morrissey, Myers-Stuart. That is a salary (in $mil) 7.6+ 5.75, 3 + .863, 5.5+2.625 fort a total of $25.338,000 . You have to eat injuries with entry level contract players, players you are already paying.
When half your starting 6 are injured/suspended, you are going to struggle. Did Chevy miss out on Stone? Maybe, he is definitely the definition of rental player, but is he that much better than Stuart? Or Strait? Still surprised we haven't seen him up with the big club as of yet.
We still have Poolman, Stanley, Kostalek and Kichton on the Moose, looking to make the jump.
