Would Buffalo have any interest. Trade centered around Fiala and Cozens?
Probably not. Fiala is likely the last player Adams wants to bring in to play under Ruff.
Cozens is also highly valued by the front office. He's being asked to actual play D under Ruff and he is having the usual growing pains of learning how to read the ice, getting ahead of the play and being in the right position as an NHL pivot. He will be fine, but it will probably take some time for him to figure things out yet.
Don't listen to the few Sabres fans who are peddling Cozens on these boards at the moment. Many are just numb from missing the playoffs for so long, and are not thinking clearly when it comes to evaluating young players and their development.
