Yes, I understand, I didn't count on success. But Kulich looked good in the center, unfortunately it is unlikely that the Wild will be interested in Cozens and he struggled this season and has a big contract. Peterka is quite an interesting and young player for the top 6.
I don't think the Wild would trade him in season, point blank, period.
I think they would consider trading him in the offseason, but any deal would be contingent on them having a replacement for him as a top six center.
In terms of Buffalo, I don't know how Guerin would value Cozens. He probably loves the size and may think he's closer to the 68 point player he was a couple years ago than the 34 point player he's pacing to this year. I don't think we can completely rule out an interest in Cozens, but yeah, the contract might make it difficult.
If the Wild end up signing Brock Nelson or someone like that in free agency this summer, Rossi may be available for a Peterka+Kulich type package.
