The 2021-22 Columbus Blue Jackets will be an interesting case study in roster building.
After trading away Pierre-Luc Dubois and Seth Jones in 2020-21, the team enters the new season with question marks at arguably the two hardest positions to acquire: a number one center and a top-pairing defenseman.
To be clear, Zach Werenski is a number one defense pairing defenseman. But it takes two to tango, and the Blue Jackets could try a number of defensemen - Adam Boqvist, Andrew Peeke, Vladislav Gavrikov, Jake Bean, etc. - opposite the 24-year old Werenski.
Interestingly, for the lack of star power on the defense corps, the Blue Jackets boast up to nine NHL-caliber defensemen, as Dean Kukan, Scott Harrington, Mikko Lehtonen, and Gabriel Carlsson all vie to fill out the roster.
