Declining Kozlov? He had four 70 point seasons after he left Detroit, just two whilst he was a Wing.
But whatever, I think trading for arguably the greatest goaltender of all time classes as blockbuster.
I just think of a blockbuster trade as involving multiple players and being somewhat of a risk on both sides. To me, pulling the trigger on the Hasek for Kozlov deal was more of a no brainer. Buffalo wanted to get rid of the salary and Detroit had no problem spending money. Detroit was somewhat set with their top 6 and getting rid of Kozlov allowed them to sign Hull and Robitaille. Kozlov did end up finishing strong with Atlanta, but he had pretty much reached his full potential in Detroit. I think it was more of the situation he was in with an expansion team. Not in any way saying Kozlov was a poor player. I was a fan of his. But I don't think many GM's would have thought twice about swapping him for Hasek if money were no object.
Holland generally likes to play it safe when trades are involved. I like the idea of the Buffalo trade. Unlike most of the proposed roster moves, it's actually plausible and makes sense. Unfortunately, I don't know as though Holland would trade Quincey, because it would be pretty much admitting a mistake. In Holland's defense, I don't think anyone could have predicted how much Quincey would regress.
