We also have to acquire all of this while Karlsson, Couture, and Hertl are getting older and probably less effective and more prone to injury, or leave the team entirely.
If we're really, really lucky, Eklund replaces Meier (with a different package of skills - I mean in terms of overall impact), but that just gets us back to where we were nine months ago (the worst team in the league). Maybe we have two other top nine forwards and two top four defensemen in our current crop of prospects (say Bordeleau, Gushchin, Thrun, and Mukhamadullin), and maybe one of our goalies turns into a decent backup.
Two years from now, we look something like this (imagine roughly equivalent players in some cases):
Eklund - Bedard - XXX
Couture - Hertl - Gushchin
XXX - Bordeleau - Kunin
Gregor - Sturm - Lorentz
Knyzhov - Karlsson
Thrun - Mukhamadullin
Ferraro - Benning
XXX
Makiniemi
Even if you fill those slots with acceptable trade/UFA options (not superstars), this is something like a 225-250 goal team (we scored 233 this year) that allows 275-300 or so (we allowed 315). We'd need a legitimately good goaltender to bring this roster even close to acceptability, and this is almost certainly overly optimistic.
Maybe our prospect luck is better than that, maybe our draft luck is too, but we're just too shallow right now.
