Can it be in between? They won't all hit their ceiling, but only two? I don't agree.
Between Guhle, Xhekaj, Struble - could one of them be a top-3 D?
Could Slaf become a top-6 forward?
Between Hutson, Dobes, Farrell - could at least one of them become an impactful NHLer?
Between RHP, Heineman, Roy, Beck, Mesar, Kidney - might two of them be middle six forwards?
Between Mailloux, Barron, Engstrom, - could one of them be a top-4 D?
I think the answer to every one of those questions is more yes than no.
And thus that is a stronger than average pool, relative to the league.
However, i do agree with you that some of those guys could be made available if it is to get an established younger strong player. The refusal to consider moving Poehling to get O'Reilly was not a good decision if the goal at the time was to compete.
I don't count Guhle, Xhekaj, Harris, or Slafkovsky to be prospects. They're in the NHL, for better or worse. Counting them against our prospect pool only artificially inflates the reputation of the prospect pool. Similarly, Matty Berniers is not a Kraken prospect.
Of the prospects remaining I don't think any of them project to be impact players in the NHL barring Hutson and now of course Reinbacher. Roy, Farrell, Kidney, Roy, and Heineman all have flaws, mostly physical, which drag down their prospect profile. It's not impossible but it's unlikely to see Farrell thrive with the Habs given how small our top6 happens to be. Roy still seems to have a bad reputation in terms of speed and skating -- it's not impossible but unlikely he can make up for it and thrive at the NHL level. Mailloux has tons of criticism laid at his feet for his poor defensive play in the OHL, playing at higher levels doesn't make it easier for him to perform well. Mesar had, apparently, a brutal year in the OHL and while his career isn't over it is less likely he is on an NHL trajectory at this moment.
We can continue this exercise for every name on this list. The only player who is genuinely trending up is Hutson and he's tiny, hopefully not too small.
So when you bundle them and make off-the-cuff estimates you're actually making it seem
better than they are -- our forwards in particular. It's very possible not one of these prospects becomes relevant in the NHL.
It's more of the Timmins era style of prospect with "high floors" and indeterminate but ultimately low ceilings. Lots of NHL GP in that cohort but mostly in filler roles and journeymen like Beaulieu and Jacob DLR.
But to finish this off on a positive note "worthless" on the trade market does not mean worthless in all cases. It could be no other GM really values a certain Habs prospect but still that prospect can make the NHL and develop into a worthwhile player. But in context of trade-values we have a bunch of worthless assets in the form of all these prospects. Nobody is giving up anything worthwhile for the likes of Mesar or Farrell, sorry to say. So it makes the desired 'quantity-for-quality' trades even more difficult to pull off because our quantity isn't good enough. That's why I was surprised to see Hughes have to pay draft picks for Newhook instead some of our many, many prospects.
