First, I guess I shouldn't have waded into a debate that didn't involve me.
Second, I'm just sharing a general worry I have--that is shared by others, evidently--that the window is going to be half-open or half-shut, depending on your perspective, but never fully open. Some of the young guys that we're going to be relying on need to be ready to take the step next season, while the veteran group is still in their prime. If it takes a couple more years for Kakko, Kravtsov, Lafreniere, Lundkvist, whoever else you want to name, to really hit their stride, that could very realistically coincide with the start of downturn in the play of the veterans. No, I have no actual evidence to suggest Panarin or Zibanejad (if he's here) or Trouba or whoever else will
actually decline, other than anecdotal stuff about players around 30, but I'm just stating a generalized concern.
Like, what if we've seen Panarin's best? Or Zibanejad's? What if Strome has that regression that so many thought he would? What if Kreider or Trouba slow down and become anchor contracts? That's all worst case stuff of course but not outside the realm of possibility. It feels like we're straddling a fine line with when that window is totally open as opposed to when it's fully open but simultaneously shutting because some guys start to decline. Now this isn't anything that it's a huge failing of JD and Gorts or anything, just a worry. And of course, as I've argued many times, windows can be reset and are fluid--like you could spin off Strome or Zibanejad or whatever for younger players and eliminate some of that worry about the "misalignment" of the youth development and the veterans' ability.
Your comment was that the window is totally open next year and would be for five years; my point was that it's totally possible that's not the case if the kids continue to progress at a deliberate pace and if the older core were to start to decline. In that case, your five year window could basically become like a one- or two-year window before you have to make big moves. That's all. It's not a huge criticism of JD and Gorton, but just a worry about what I see as a slightly tenuous roster construction.
EDIT: Just to further clarify, I was not opposed to re-signing Kreider or signing Panarin. I supported the former and was initially on the fence about the latter but came around to the idea. So, I'm not saying it was wrong to do either of those. But, some people did say, "Hey, if we're really rebuilding, maybe these aren't moves we should be making." I think that's what the other person was alluding to.
