Wednesday night or early Thursday, depending upon the time zone, those narratives collided, with the Mammoth acquiring Peterka in a trade with the Sabres, with forward Josh Doan and defenseman Michael Kesselring going to western New York. Landing Peterka in trade, then immediately signing him to a five-year extension worth $7.7 million annually. Trades can often be about creating more options for a team, and Peterka gives the Mammoth quite a few. The most apt word one could use to describe what Sabres GM Kevyn Adams received in return for Peterka? In some ways, the Sabres were able to get that by receiving a pair of NHL players in Doan and Kesselring.
