OK, I agree with you. But let's take this one step further. As fake GMs, we can't get caught in a bad situation, so we have to think this all the way through. Knowing what we know about the players involved (Bean, Fleury, Sellgren), and our team needs, what's *likely* to happen?
Given our depth and players coming on the left side and how they fit team needs, it seems likely that Fleury will eventually face the chopping block here. If that's the case, isn't it better to get out in front of it instead of being backed into a corner down the road?
To me this is the ultimate question, and I think I have a different take than you on it.
The fact of the matter is that when guys aren't full time NHLers, their value is skewed and lessened regardless of circumstances. Adam Fox is one of the very few exceptions, but even then it was due to a unique situation in which he made it clear he didn't want to be here.
Any trade of Fleury at this point, straight up, would get us what, a 3rd? If he's not an NHLer he's still a "prospect" in the minds of many, and prospects don't usually move for something useful.
So what's the value of getting out in front of it? The 3rd round pick we'd get for him?
Now, if we're playing the forecasting game (which, as I said, I 100% agree with you that we should and need to think about this all the way through to the end), there's another timeline in which Fleury starts the year in the top 6 due to TVR's injury. I think it was 6 months back at the beginning of May? So he'll miss a full month of the season which puts Fleury in the lineup (even if we don't move another dman out). So say he plays that month, scores an NHL goal or two, and generally holds down a regular shift. Now the narrative around the league (and as much as we'd like to give GMs and scouts more credit, narrative still rules the day in many cases) is that the Canes are getting TVR back and will have a logjam, and now they have a legit young NHL player on the block. Which, to be clear, is what many of us believe is the situation anyway (I personally think he's more of a non-prospect than many, but I bow to the hivemind for the purpose of the argument).
It'd be the same thing in Edmonton by the way. If Puljujarvi starts the year in Edmonton and puts up .5 PPG (even next to McDavid), he'd net them way more than if they traded him right now. Fleury's in the same boat, and when the difference between "getting ahead of a logjam" and seeing how this will play out is like a 3rd round pick, I'm more inclined to see how it'll play out. Even just the label "young NHL defenseman" vs. "NHL/AHL tweener" can significantly change the way he's viewed around the league, and recoup some value fairly quickly.
