I don't see how that is so much better. Raymond can be replaced (and likely wont keep any sort of decent pace when Sedin gets back). I would take Miller over Bryzgalov just because of the team he plays on and I think they are pretty evenly matched skill wise. And I would definitely take Parise over Zetterberg, if not because he is a better player then because LW is more valuable then C. Really, I don't see how what you got is a lot better considering you still would have had to drop someone for Raymond.
Either way, I don't see this being a really bad deal for him.
