And do what precisely? Forwards and defensemen are a bit different entering the league. Systems can be quite forgiving on a rookie forward as long as they produce more than expected.
If a defenseman is called up, and thrust in a top 4 role, and remember there is no Vis next year, if he can't cut the mustard defensively the impact will be massive. One or two vets go down with injuries, which is fairly commonplace for defensemen, and what's that leave you with? Defensemen take time to acclimate. I would agree with you that in the next 5 years guys will eventually trickle up and start earning the title of top four defensemen, but if you are trying to make the case Tryc, that Pedan or Reinhart, CdH, etc., are going to get some games this year and suddenly morph into solid top 4 material next year I don't know what to say. And asking you that question, I don't really think you think that either, so please don't take this as some form of assault on your hockey intellect. I just don't see the silver lining in waiting and not investing in at least one solid top four to get the team through the next few years. Other teams do go out and trade for needs on defense even with a youth "build" like the Avs have. How come they can do it, and we can't? One thing I notice on their defense... No shortage of guys over 6'1". Not that tall/big defensemen can't suck, but just look at what we have. Hamonic, and Carkner, and **** after that in terms of size.
