Travis Hamonic's position on the Senators' roster may be challenged with the addition of Calen Addison, who is vying for a spot as a third-pair right defenseman. The competition for that role is considered low, suggesting that even a replacement-level player could be seen as an improvement over what Hamonic has provided. Addison's puck-moving abilities offer a different skill set compared to Hamonic, highlighting the potential shift in team dynamics as they evaluate their defensive options.
