The Utah Mammoth pulled off a blockbuster trade Wednesday night, acquiring JJ Peterka from the Buffalo Sabres.

Utah acquired forward J.J. Peterka from the Buffalo Sabres in exchange for defenseman Michael Kesselring and forward Josh Doan. Peterka, who would’ve been a restricted free agent, agreed to a five-year, $38.5 million contract extension ($7.7 million average annual value) with the Mammoth as part of the trade.

And so the latest significant move for Mammoth GM Bill Armstrong? Landing Peterka in trade, then immediately signing him to a five-year extension worth $7.7 million annually. Sinc
