There is a massive difference between loosing your future starter to waivers and loosing a 3rd pair defenseman to waivers. There is no world where they will value Barron as high as they did Primeau
....... Not sure if you're just being ridiculous to not deviate from your argument, or just ignorant to Habs players (probably the latter). But I don't think anyone, including Habs management, see Primeau as a future starter. Heck, most don't even see him being more than just decent backup.
As for Barron, I've said this before, just because Reinbacher and Mailloux have surpassed him, doesn't mean he has magically become worthless. It's not MTL's fault they have one of the deepest defense prospect pools in the NHL. Put Barron in the Islanders, Bruins, Lightning, Penguins, etc. prospect pools, and he's easily their best or 2nd best prospect...
Barron has proven offensively he is a top 4 NHL dman, but definitely still has defensive issues, which is where the Nils Lundkvist comparisons come in. But, as you mentioned, Barron losing his waivers exemption (where Lundkvist still had 1 year left) will have an impact on his value.
