Your absolute confidence in mediocrity is impressively resolute.
What were Texier and Bemstrom a year ago? Texier was valued about where Foudy is now, and Bemstrom wasn't even on the radar, perhaps a bit above where we now rank Karlberg. If we had a similar debate a year ago his name would not have been mentioned. I think it's unlikely we'll have similar good fortune with the next cohort, but we don't know. Could be that we get NHLers out of Hjorth or Marchenko, or neither, who knows. Being unsure of what the results will be is not the same as "Noticable lack of forwards", it's just how prospects work unless you're drafting at the top.
My point about "replacements" is that what ultimately matters is the NHL roster. And if the NHL roster is overfull of young players such that the next group of prospects is blocked, then any shortfall in the number of prospects is just an abstract issue. Hockey's Future would talk about such a situation in stark terms, but how important it may be depends on what's going on with the NHL roster.
Firstly, stop with that over-dramatic commentary. I said the lack of prospects isn't as big of a concern due to the age of the NHL roster. Is it a concern? Yes, because a lack of prospect pool means we can't really pull of trades since we don't really have picks either.
Texier was near the top or at the very top of our prospect pool at the start of last year. I had him personally at
#5 because of his injury history. I had Bemstrom at 14, but as a potential riser. A lot of people wouldn't say Elvis or Gavrikov were prospects anymore due to their age, so if you want to go by that, he was 3rd.
Most of the prospects you mentioned (Hjorth, Voronkov, Karlsberg, Marchenko, I'll even put in TFW) are all question marks. Yes, question marks can go positively as well as negatively. I still don't know whether or not to believe in Foudy. So it goes. Almost every prospect pool has its share of questions and almost all players have their questions, but we're banking on at least a few of these very big question marks to become good. Which is my point about our prospect pool being bare in 2-3 years, because its already shallow and we don't have the picks to replenish it over the next 2 years as of today.
Completely agree with your last paragraph, because it's mostly what I said in the post where I was "confident in mediocrity". Our NHL group is young enough at the most important eras where we can survive a few years of a bad pool as long as we keep those guys.
