Re: The rebuild.
It really depends on how you define rebuild.
We've completed the strip down and laying of the foundation (Eichel/Reinhart/Risto), we've supplemented that core with veteran pieces (Kane/O'Reilly/Okposo). However, I don't think we have a fully functional core group to contend with.
The problem is, the D is still severely lacking. Even if you consider McCabe a core piece (i don't at this point) we still need at minimum one more d-man to really have a foundation there. So, we've gotten, IMHO, the hardest piece to get, thats the #1 Franchise center. However, if Eichel is the foundation, then we still need structural beams in place on the blueline.
Nearly all contenders are a group of 3-4 core forwards and 3 d-men. We don't have that yet. So, IMHO, the rebuild is still 'active'
I have said it before on hear but if you look at the past, 10 years, each Stanley Cup Champion has had an elite center (Crosby, Kopitar, Toews, bergeron, datsyuk) and in many cases a top tier second line center. An Elite Defenceman (Letang, Doughty, Chara, Keith, Lindstrom) and finally an Elite Goalie (Murray / Fleury, Quick, Crawford, Rask, Hask / Osgood).
We could add coaching in there but I think 80% of this board would discount Dan the Man, but, I digress.
The only elite talent we currently have is a Center. That's not to say Lehner or Risto can not become elite players in the NHL. As of right now Lehner is not going to win enough games, by himself, to make a difference; and Risto is not going to carry the flow of a hockey game. Those are things you need, multiple difference makers.
Look at St. Louis, they are a very good team and have been for years. Yet, they can never get over the hump. They are missing that Superstar Center. In Washington its that Elite D. We can look at Nashville, they are missing that Elite Center, RyJo just didn't work out. The list goes on.
Well, that's just my perspective.
