The Edmonton Oilers currently have ten defensemen who played NHL games last season. Most would agree the top five D-men are Evan Bouchard, Mattias Ekholm, Jake Walman, Connor Murphy, and Ryan Shea. Bouchard is their top-pair right defenceman, will run the power play, and he will play the most minutes. Murphy is the second-pair right D-man and will anchor the first penalty kill unit. Those are the only two spots in the lineup I feel are locks when training camp begins.
