One storyline last season was how the Buffalo Sabres' success brought about new and old rivalries. In the opening round against the Boston Bruins, tempers ran high in the Sabres' series victory. In Game 6, Bruins defenseman Charlie McAvoy delivered a slash with both hands against Buffalo winger Zach Benson. The Sabres will have a chance to play McAvoy and the Bruins the first time on Jan. 5, 2027That game will be in Boston. McAvoy and Benson may have an ice rivalry that is emblematic of how the Sabres and Bruins may be viewing their matchups next year.
