JJ Peterka traded to Bruins after disappointing season with Mammoth
Summary

JJ Peterka has been traded from the Utah Mammoth to the Boston Bruins after one season in Utah. Initially acquired from the Buffalo Sabres, Peterka struggled to find his place and ended the season in a bottom-six role. His performance fell short of expectations despite a strong previous season in Buffalo where he had nearly 70 points. The Mammoth aimed to open roster spots for younger players, with general manager Bill Armstrong citing a need for competition among up-and-coming talent. Peterka expressed hope that his fit with Boston will lead to a resurgence in his performance.
