If the Sabres are not going to retrieve a top 6 forward from a Bryan trade, then just keep him. With him, our blue line would be a quality unit with an offensive bent.
The hope will be that players such as Quinn, Kulich and Benson improve to compensate for the loss of Peterka.
This franchise created a toxic reputation that has foreclosed a lot of player options. So if you can’t get a fair value back in a deal, then accept that ugly reality and work with what you got and do your best to maximize it.
