At the outset of this year’s training camp, DJ Smith made a declaration that piqued my curiosity: he would be trying Thomas Chabot and Artem Zub, his two best defensemen, together as the team’s first pair. For as long as Chabot’s been the Ottawa Senators’ top gun on the blue line, the Sens have been on a quest to find him a suitable partner. The only person who had been up to the task before this year was Dylan DeMelo, and he’s been gone since the 2020 trade deadline. Others have gotten a kick at the can, most frequently Nikita Zaitsev, but nothing’s stuck.
